Golf R Oil Catch Can Install ~ MK7, MK7.5 MQB

In this video we install the Racingline Catch Can for MQB cars. This catch can install will replace the OEM PCV valve and fine oil separator. I will show you step by step how to install a catch can for most MQB VW and Audi cars. Also the Golf R catch can installation requires relocating the top of the washer fluid bottle. We will also be testing how much this catch can ACTUALLY works to keep carbon off the intake valves. #humblemechanic #golfR #VW #MQB

Something I wanted to add about this can. I don’t really like the fact that you have to remove the engine mount bolt to remove the can. I think using the stud on the bolt would be perfectly fine to hold the bottom of the can. With this setup, technically you will have to buy a new bolt each time you remove the can to empty it. While the bolt is cheap, it’s silly to have to order a part, just to empty the catch can. I also think that if something like thread locker is required, it should come in the kit. Id rather pay $3 more than have to deal with getting my own thread lock. I actually feel the same way about the bolt and the seal too. INCLUDE IT ALL!

[@CarbonCopied29]

Encountered this same thing on the AddW1 can I just installed in my Elantra GT - now that you mentioned the torque spec I'm gonna go check it out. Also going to get an easy drain fitting so I don't have to remove it.

[@michaelblacktree]

I agree about the mounting bolt. But maybe they were following in the spirit of replacing hardware every time you work on your car? 🤨

[@Urbanmk7]

I was really surprized about it not including the seal.. pretty cheap part for an expensive item. Also agree about the SAE part and mounting of the actual can. Glad i went with spullen on this. As always, great video man!

[@TomCuthbertson]

When i finally get one I'll be getting one of these if they're still around. You'd think there would be a drain plug at the bottom. www.ezmods.co/product-page/catch-can-quick-release-drain-kit-for-racingline-catch-can

Super psyched you posted this video, as I just ordered the same can the other day and wanted to have a comprehensive reference. Here’s a solution to your bolt concern (ordered mine so it can be installed at the same time as the cam itself): industrialtecsupply.com/products/fumoto-b106sx-360-degree-rotatable-motorcycle-quick-oil-drain-valve-m14-1-5

Would absolutely love to have a mechanic like you working on my car...

[@alanrich1170]

You're right - there isn't much baffling inside the can. It's not going to do much for cleaning up a fine oil mist. On my Audi track car (similar engine), I tried 2 different catch cans from 2 of the big names in VW-Audi performance stuff. I based how well they worked on how much crud was found in the can, and also how nasty the insides of the intercoolers were when I took them out for cleaning. Neither big-name catch can did squat. So then I tried an actually engineered (German) catch can- the Mann ProVent. It has all kinds of functionally engineered innards including a high-oil-affinity gas filter. It frikkin WORKS orders of magnitude better. Downside - they don't come in kits - just different size units so you're on your own for fabricating virtually everything you need except the can itself. The other thing, regardless of what can you have, on my engine there are 2 ways for crankcase gasses to get into the intake, depending on what the PCV sandwich thing is doing, either into the intake manifold or thru the head down into the turbo. Both paths must be defeated to keep the intake 100% clean. Not even the Mann ProVent can clean with 100% efficiency, but the others were a joke.

[@busterscrugs]

I had no idea Mann made a catch can. Just looked into the ProVent 200 and it's a beast! The one Charles installed likely won't do a thing with the lack of any real baffling.

[@-CLASSIFIED-]

pretty sure your supposed to fill the can with steel wool

[@jasonmajere2165]

How much efficiency are the intercoolers losing from all the crud.

[@Ljbuddy12]

I installed one of these on a 2007 GTI with the FSI engine and based on my experience these catch cans do not help prevent carbon build-up on the intake valves! The valves still had to be regularly cleaned around every 60,000 miles. Just my experience

[@HumbleMechanic]

I Am expecting the same thing.

[@Lucas-ck1po]

Depends on the internals of the can, its efficiency and if there's a secondary breathing outlet from the head into any part of your intake. Speaking from experience too. I've been dealing with a few projects myself and from what i can tell is that the majority of catch can systems out there will prevent thick oil from oozing at the intake system but they don't stop fine particles suspended in the air. Not to mention the cylinder head breather, than normally goes into the unpressurized end of the intake, just before compressor. I've dealt with a car that had issues constantly with black gunk forming around throttle which caused idling issues and MAF errors constantly. The catch can helped but didn't resolve it all, i was still having gunk forming around the throttle but it was taking twice as much time to happen. I've seen another project with a small volume industrial coalescing filter after the catch can. The can was retaining the big oil flow but the coalescing filter after it was picking a big flow of a black, oily water. And the flow wasn't that minimal, it was considerable. Also, another coalescing filter added to the head breather would help but in that case it wasn't neccessary.

[@raoulrr]

@@HumbleMechanic I can guarantee you won't see anything in the catch can from street driving, BUT you'll definitely see oil if you track your car. When I was on the track without a catch can, threshold braking with track pads & sticky tires would get oil to overwhelm the stock PCV and puke in the intake, leaving behind me clouds of smoke to the point where I had the track marshalls ask me about it.

[@chrisselke449]

Install water/methanol system. My 2013 CC was just scoped at 42000 miles and there is ZERO build up. It’s all clean inside the engine. Water/meth has also enabled me to run APR Stage 2 104 octane tune. I run this tune 100%. The W/M is controlled by the MAF. It only sprays when I drive aggressively. Has never caused a single check engine code in almost two years 20000 miles. Just add a couple bottles of yellow HEET to -20 washer fluid and use the washer reservoir as dual purpose. 40-50 degree cooler intake air temps, super clean engine internals, ability to run 104 octane tune. And for not much more money than a stupid catch can.

[@mercury0214]

Less blow by at higher rpm is worth it though

[@miketeeveedub5779]

Entertaining video as always Charles - you manage to detail the entire process clearly and succinctly without it sounding like a lecture. BTW - Someone should make a retrofit kit to have a 5th fuel injector tap into the air inlet tube downwind of the MAS to act as a de-carbon valve/runner cleaner. Almost like a Mk1 CIS cold start injector. It would require a reprogram of the engine management software to run at certain intervals and a modified fuel curve as to not run rich. Sure beats a +$1000 service every few years to clean the engine. Probably a liability and warranty issue, but still just a thought. Cheers!

[@raviolisauce103]

Woah, I thought I was gonna watch a video you've already uploaded but, apparently this is a new one. Sweet!

[@UltraGamma25]

Same

[@jerryx2000]

Any update on this? How are the valves & did this prevent carbon build up?

[@HappyDude1]

Hello sir Could you tell me if the audi s3 from 2016 also has a lot of carbon build up ?

[@blueridgerennsport]

I've been disappointed in some of the "baffled" catch cans that I've installed in customer cars and even my own. A long time ago I came across some no-name heavy-duty steel "pot scrubbers". Not really steel wool, but much thicker. Anyway, the stuff was super cheap and sold in bulk so I bought a bunch of it and have been using it to stuff into non-baffled and poorly "baffled" vapor catch cans. It works especially well with cans that have a tube on the inlet side. I've tested two very different motors with and without the steel media in the catch can and having it made a big difference in both applications with a lot more liquid collected in the same number of miles driven.

[@Tall_Pauly]

15:36 Reusing the front engine mount bolt until you have to take it off "next time" eh? Upgraded Engine mounts video confirmed???

[@HumbleMechanic]

:)

[@IRico_chetI]

Bei einer solchen Modifikation erlischt leider die Betriebserlaubnis und ihr Kraftfahrzeug fällt durch die Hauptuntersuchung. Guten Tag.

[@BigDaddysGarage]

Rico Rodriguez that's exactly what I was thinking!

[@yah5o]

I thought that there were some catch can sets "with TÜV" that are actually street legal. IIRC this might have something to do with "open" systems that vent the gases through a small filter into the atmosphere (illegal) and closed systems that route the gases back into the intake manifold. But don't quote me on that (probably wrong)

[@Me-sb3mx]

Bro can you make video about DSG , How reliable is that , is it better than simple automatic , what disadvantages DSG's have if we would compare it to automatic trans. And about common problems , what problems did you meet with DSG working as a technician ,thanks

I hate it when imperial sizes get snuck in there.

[@eldom20]

They're AN (Army-Navy) fittings and bolts, so you'll definitely see imperial sizes there

[@neobieneo9319]

Hi sir. Can u teach me where and how to install an oil catch can for EA211 1.4tsi?

[@therealderjett]

This was a great video! In Ohio using a catch can is based on how much time you have to maintain it. If you are running it year round it needs to be checked weekly if the temps are below freezing and hitting negative numbers at night. After I got married I got rid of it because it took way to much time to check and empty it or verify nothing was freezing in the lines.

[@AkerMehanik]

Cool, Bro. Perfect video end performance. I am sorry my England 😊

[@Viages]

Over priced product , hoses and accesories “look” cool BUT the main goal which is the can itself and the filtering process is shit !! It doesnt have any bronze filter

[@dorkultra]

wouldn't this mean that you need to dump it every few days when it fills up with water?

[@eppyz]

These are all automatic fail at a smog check here in California. ANY modification to the emission system in California is an automatic fail.

[@acefighterpilot]

Such a great experiment. Frankly I think the cyclone separator that is on the stock car is more efficient. I'm eager to see the result though we all might need to get used to walnut blasting every 30k miles or so. Because the rate of carbon build up is likely linear, when you clean the valves again if you measure the thickness of the coating first you can project how much carbon it might have at a particular mileage. Hopefully you put miles on it quickly.

[@Eli07K]

Last month I bought CTS Turbo Oil Catch Can Kit via ECS Tunning. Similar kit for a 2016 Audi S3 8V. Installation was pretty straight forward just like this kit. The kit looks great. After I installed the kit, the next day Check engine light on, rough idle and misfiring on cylinder 1 and 2. So I started troubleshooting, Coils were new a week old before catch can install so as spark plugs. Reverted back to OEM spark plugs and coils same issue, finally EPC light on, car when into limp mode. That's when I finally decided to remove the kit. I returned the kit back, ECS Tunning send the kit back to CTS. By the way I attempted to contact CTS and got no response. CTS costumer service sucks. After several weeks waiting ECS contact me and they issue a full refund. ECS Tunning told me it's rare for them get full refund from the manufacturer and no restocking fee. I almost bought this kit that you install. But I was concerned to have the same issue. Audi's seems to be very picky and sensitive with vacuum. I'm convinced the issue was cause by a poor design of the PCV Oil valve replacement plate. And so I bought ECS Tunning Oil Catch can that retain the OEM Pcv valve in place. Been running it over a week with no issues so far. My only complain with this kits. Is that they don't have a petcock valve for drain. That would be great to have. To avoid removing the catch can. Just like in this kit the mounting bracket does not let room to install a petcock valve. I would like to see a manufacturer coming with a bracket solution for it. Only kit I have seen with a petcock valve is Spulen oil catch can system.

[@HumbleMechanic]

That’s odd. I would have loved to check crank case pressure on yours. Lol

[@Eli07K]

Charles, I just started watching your videos because I am considering the purchase of a Golf R. I have to say that I'll continue coming back to your segments. Thanks for all of the details that you provide and the additional comments to help make sure the projects go smoothly. GREAT JOB!

[@HumbleMechanic]

Awesome!!! Thank you. Can’t wait to see your Golf

[@eldom20]

I like how you're so careful with the AN fittings. In the USAF, we just snug them up with open-ended wrenches, safety wire them, and call it a day 😌

[@eronan03]

eldom72 because safety wire, when done properly, is amazing.

[@Randy245850]

Is this kit really worth 540.00? Do you really need this?

[@HumbleMechanic]

It’s the nicest kit on the market. I struggle with these kits because they are all $$$. But this is not something you NEED! For many people I really think it’s just under hood decoration

[@christophergomez2381]

Man, you are da best... keep it going 🙏💪

[@ABeans07]

So I don't get these kits. Where is the actual valve now that the OEM unit is gone?? This is just a plate, hose, can.

[@ABeans07]

This isn't just the racingline kit. Seems like most of the ea888 aftermarket.

[@Honky_Konky_Phooey]

In the uk we make drain kits, banjo bolt for the bottom of the catch can a small valve and rubber hose, no more removing the can to empty it 👍

[@HumbleMechanic]

I like that a lot. The BFI can I installed had that too

[@siralexu]

I'm really looking forward to the before and after catch can result but i guess we are going to have to wait a while for it

[@luisitolasvegas]

Question: That drain plug seems a bit tight and/or hard to get to. Would I have to take out the tank each time to empty it, or how would that be emptied out. I have a Mk7 GTI and want to add this same catch can, but am wondering about your experience emptying it out. As Always Great Video, Thank you.

[@itsarthy]

Hey man, big hello from Oregon! You inspired me to buy a mk7.5 golf R honestly and I’m picking it up later this month. The quality of these videos is amazing, definitely the best golf R owner on KZbin.

VAG/VW use 18 mm metric bolt. It is typical for example in EU.

[@Krispy95]

I installed mine a couple months ago and the hardest part was taking the pipe off the turbo inlet and trying to make the gasket stay. Lol the rest was easy. Already see it collecting oil in the catch can. Probably going to dump whatever is in there now soon.

[@Zozert]

I just received my cts catch can for my mk7 gti, nice surprise to see this video drop today.

[@HumbleMechanic]

awesome! I wonder how the install will go vs this one. I liked that their kit ran the one hose around the backside of the engine

[@jtsherri]

Great content as always, Charles! Do you happen to have links you can post for the PCV gasket and engine mount bolt you recommend replacing?

[@dorkultra]

$540 for a catch can, hmmm, i'll just bring it in to get a valve cleaning every few years

[@georgedanilopoulos3023]

You are SOOOO right. Also at 21:30 look like it is a cheap one in an expensive box

[@mercury0214]

Yeah but if you run at higher rpm that extra pressure is not gonna make your engine happy.

[@chrisselke449]

My 2013 VW CC has 42000 miles and ZERO CARBON build up. A catch can will not prevent it. Water/Methanol injection keeps the engine very clean! I installed it at 22000 mi. I will install a Mann Provent 200 oil/water seperator to properly catch what people think these catch cans do

[@Nultic]

Do you prefer this style of catch can? I installed a 034 Motorsports can on my car with the "Africa" plate and found I was having massive amounts of blow by to the point I'd probably need to empty every week. I actually am looking at re-doing my setup so that it piggy backs off of my Mk6 GTi PCV and just putting a can between the PCV and inlet. Have you found this to be the case with this style of catch can? Thanks.

[@MauriceEllerbee]

Oddball question but curious. Would this possibly fit on a 16 Jetta Sport 1.8T manual? Looks pretty swappable but possibly may have a washer fluid location issue if I remember correctly.

[@CarbaCars]

Any idea why when I go on spirited driving and the catch can is installed I get errors from the car. Such as the car goes into a limp mode because the the car starts misfiring from 2 cylinders, the two cylinders where the catch can is located above.

[@ultimate1576]

AN fittings (Also called JIC, 37 degree flare, etc) is an SAE J514 standard, so if you want to use AN fittings you're going to have to live with imperial dimensions. There are metric flare fitting standards but are far less common.

[@HumbleMechanic]

but I don't have to like it. LOL

[@corradokid90]

Question Charles..... why would you need the special AN wrenches when you solved the problem of not having them so simply and cheaply??? Just wondering. I agree with the non metric bolt on a metric bolt using car.... but I'm picky like that as well. Lol

[@HeathRS]

So is this an actual PCV replacement or PCV removal and a baffled setup to redirect to the catch can? It's pricey and I'm just trying to decide if this is worth it for my setup, especially for a car that is also daily driven.

[@peanutbutterisfu]

Idk if ur familiar or not but the best way to clean the valves it walnut blasting cleans much better and faster then trying to use brushes like you were in the beginning of the video. I personally just tape off the intake ports and just leave the one open that I am cleaning at the time and I have a shop vac running while I’m blasting. You can buy these foam inserts to block off the intake ports or even make them urself out of foam but I just use tape. After I’m done with whatever set of intake valves I will use a brush with some spray solvent to get the last bit of crap out and use a blow gun, then tape that port off and move on to the next one.

[@jaywillsey6797]

Would you explain how this vents crankcase pressures since you are replacing the PCV. I have a CTS with an Africa plate and don't know how it vents pressure to prevent excessive blowby and engine damage. Thanks

[@dramchaser1022]

I installed the Black Forest catch can on my MK7 GTI about a year ago and the catch can is always dry. Not even moisture accumulates. Have you ever come across on something like this? Is the catch can even doing anything? Thank you and as always I enjoy your videos. Keep it up.

[@lexioncombine9403]

The banjo fitting is SAE because they are trying to use up stock made in 1950. It's 2021, nobody uses banjo fittings now. :p

[@lang9872]

I did also install sn oil catch can in a VW 3 cylinder 999cc TSI that was bought new in January 2020 with direct injection but after 10.000km the catch can was stil empty. It was installed well so I do not understand why... Do they use some sort of new oil or what could it be?

[@rossbowman202]

The kit needed more triple squares. 😂🤣😂 Why can't they just design the can to drain the oil back into the engine? On old aircraft with wet vaccum pumps they have catch cans and the oil drains back into the engine. It is 50s technology.

[@YT-kh1sl]

Bro, if this is such a problem why doesn't vw preinstall this. "A top engine clean" is not scheduled maintinence on a mk7.5 gti. What gives, is this a problem or not?

My guess is, it will fit. But I have not installed it so I can't say 100%

[@JasPlun]

I chose Toyota no catch can needed they provided a real salution with D4S duo injection no more carbon problems. Why has VW not adopted this approach as of yet?

[@jamesengland7461]

Ah, the good old days of $2.99 PCV rattle valves...

[@davidwright1653]

Why didn't you use a universal adjustable metric wrench on that standard bolt?? How do you drain the can once it's full? Do you have to remove the whole thing and pour out the liquid? Or undo the bottom drain screw which hopefully is accessible from below? Might need to install a petcock valve on that can?

[@S54VR6]

I don’t even have a golf r or a mk7 gen for that matter but I always appreciate these great videos

[@TrueBlueEG8]

Could some other manufacturer please show VW how to make a proper crank breather system for their engines?? They are seriously sludgy , especially here in Ireland, with the amount of moisture in the air. The stock pcv systems have been a problem for the last 30 years.

[@alexlong6103]

So what do you do for crank case pressure?! You should really tell people that drive with spirit that these closed loop systems create pressure. I installed this on my Audi TT and kept blowing out main seal. Took it off and made my custom setup so I can catch blow by and still release the crankcase pressure. No problems.

How is possible carbon build up in golf r if there should be a dual injection system...direct and the mpi ..so the second one should clean valves when its work.....great canal...best regards from europa

[@mkefayati473]

I maybe a bit late, but if you empty your catch can in COLD temps, and that means every time you drive and you stop. it sucks, but its better than taking it off or on! BFI ( Black Forest Industries ), have threaded the bottom of the catch can so you can install a valve before you install the catch can, a valve with a tube attached to it, open it, empty it! volla!

Hi Charles....is there a catch can kit more cheap? Why you must remove the oem cover on the head engine ?

[@CFG39]

I’m shocked how bad the carbon build up was on your R. My old 2011 MINI Cooper S didn’t have that much buildup at 60K miles. Whatever BMW/PSA changed on the 1.6T engine for 2011-2013 models drastically reduced the carbon accumulation problem that plagued 2007-2010 models. VW still seems to have substantial carbon accumulation issues. I know all DI engines suffer from this to some degree but at only 10K miles you don’t see that much buildup on Ford, GM or Mercedes engines. I wonder how much carbon had accumulated in my GTI before I sold it with 45K miles. One thing I learned recently that also shocked me: VW, in their cost cutting pursuit of recent, has completely ditched the dual injection system GLOBALLY. No post-WLTP EA888 engines have MPI and DI. I was really hoping we’d get that here in the U.S. with the Mk8 GTI, but it appears that hope is gone forever. I wonder if we will get GPF or if they will leave those off US spec cars. I also wonder if VW/Audi will switch to an all aluminum 2.0T (maybe based on the EA211?) or if they’ll keep that only for the smaller

[@drazgul1]

I know you don’t get these but SEAT Leon Cupras with 300hp included dual injection (these are 2018 models) And it’s the one I’m getting due to this whole issue with carbon buildup

[@CFG39]

David No I know all about the Seat Leon Cupra, it is just a FWD Golf R essentially. It’s a shame the new VW Group engines (Post-WLTP) have gone back to only offering DI (NO MPI) and to comply with EU PM2.5 regs they’ve added a gasoline particulate filter. IMO, just one more expensive thing to fail. So now you’ve got all the old direct injection problems, your car no longer sounds good because the GPF acting like a super restrictive muffler and catalytic converter and if anything goes wrong with the GPF it will likely cause the engine to go into some majorly reduced performance mode or even force a shutdown like diesels with DPFs. At least here in the US our cars won’t have GPFs for now.

[@drazgul1]

@@CFG39 Agreed, both changes sounds like more problems to own one of them. Retarded decissions, I don't even mention the new generation of VW group cars, and it's not even because of engines, something as simple as having everything on a touch screen is a big argument not to buy one. I am surprised you even heard of these cars by the way.

[@CFG39]

David No i have owned more VWs than any other brand. All have been Golf GTIs. I was like you in not really appreciating the large touchscreen in cars, but after using a Tesla Model 3 I can say if done properly, it can make things quite simple, less cluttered and the biggest bonus is being able to have software updates remotely beamed to the car remotely. I haven’t been able to see a Golf Mk8 in the flesh to see how it’s infotainment systems work so I don’t know if it’s good or not. I really wish VW offered SEAT in the US. I think their cars are more stylish than the VW alternative, but we will NEVER get that or Skoda here. I honestly think SEAT would be more successful than VW, but that’s just my opinion!

[@drazgul1]

F C I do think SEATs would be pretty successful over there too haha. I can’t agree with how touch screens are implemented in the latest Golf (or Leon, too), that said I have not tried them but I can’t shake the feeling a physical knob or button will always be in a specific place, where I don’t have to take my eyes off the road just to put the AC. But that’s probably something that could be debated and that would eventually be a non issue when cars drives themselves

Hi! I have some questions about the design of the Oil Catch Can that you use. The hole at the bottom left (when you see the inner side of the original PCV) is actually linked to the crankcase, and the hole at the right side of it is linked to the position behind the throttle to generate negative pressure. So, based on the design of the Oil Catch Can, since they do not have a hole on it, it seems that the pressure in the crankcase is not easy to go out.

[@grahamek86]

Couple things... why not reuse the spring clips off the old N80? You cut that N80 hose a bit short. 15:00 That's an aircon hose, not a coolant line. It's also worth clarifying that you're not getting rid of the washer bottle, just reducing it's capacity by removing the secondary bottle. The lower bottle remains.

Thanks for posting HM. Stay safe and healthy. ✌

[@HumbleMechanic]

You too brother!

[@fernandoromero6336]

I have a 1.4 Jetta and with 20k miles the valves were caked in carbon, I followed your video on how to clean them. Now on my EA211 I have to oil catch cans, one from the PCV to the turbo and a second for the oil separator under my intake. Idk if you my have one

[@ronwalsh]

I have used catch cans from Billet Technology on three cars, a Mercury Cougar 3.8, and my 65 MGB. I installed one when I purchased my 2010 Dodge Charger and I can tell you they work great. No need to remove the can to empty it, just screw off the bottom part, and dump out the oil. The BT cans utilize stainless steel mesh to catch the oil. I would recommend one of these cans, even if you have to make some mods to make it fit properly. Just my $.02 of course.

[@1state152]

@HumbleMechanic can you tell me how I can install a catch can on a 2020 Audi q3 2.0t? I cannot find any reference for these newer engines. I have a universal baffled catch can. Thanks in advance

[@LazyRASHO]

I know it's the worst for emissions but venting to air is BY FAR - The best method for protecting your engine! I did it to my MK3 16v GTI Golf way back and when I got my 2.0 Tfsi Eos I looked into these catch cans and just by looking at them I knew they're just useless and as you know those gasses are way more harmful to the TFSI so I just got a PCV Delete plate and ran both hoses (the one from the engine cover and the one from the oil pan) into a Y-pipe, then down and back to the rear wheel.

[@leftisnal]

After using all kinds of catch cans on my mk7 tdi without results ,i pluged the pcv turbo inlet and rerouted the pcv to the back of my car venting it to the atmosphere using cheap 19mm silicone hose . cost: 10 euros + 30 minutes work.

[@AP9311]

I watched the video.... I'm not sure of the washer relocation,....i really don't like the tiny black bottle. But I was thinking about a "modified" washer bottle in front of the engine, by the fans. Like have a plastics company measure, injection mold plastic to form a redesigned washer bottle.... just my 2 cents idea lol. I like the catch can idea. I want that in my sub. Soon.

[@Mulhim966]

Why can't we install universal catch can on mk7s ?

[@gmax985]

Hi Charles, when do you plan on checking to see if the catch can made a difference. Also, if there is a difference, I plan on doing this to my car, a 2015 Audi A3 Quattro. Do you think it's fairly similar to your engine?

[@HumbleMechanic]

I wanted to be sure I get a good amount of miles. Maybe at 20k

[@badboysweetheart1]

Hey man great video as always, removing the bolt every time def sucks but it looks really good...I have a question un related.. I have my mk4 GTI and swapped from 5 to 6 speed also from dmf to smf.. It shifts fine if not running.. When started it wont go into any gears.. I was wondering if there is anything else to add during this swap or is it most likely air in the line..??? Any insight I appreciate..Thank you ...Love your videos

[@brianpearson2532]

And exactly how does that factory PCV valve work anyways? Was it designed to prevent gunk from traveling back into the intake or is it only meant to vent the crankcase? Could VW redesign it and make catch cans unnecessary? So many questions... 🤔

[@arthurrodesiler3109]

BTW were did you get that pump for draining the wiper fluid? Also I hate plastic crap on the engine as it gets older it crack's so easy. Guess I can find one on Amazon I guess. I always used a Holley red gasoline pump and used fitting and made my wires with a clamp's for the battery and hoses I bought..

[@JosePerez1973]

Arthur the pump looks like a YaeTek (amzn.to/3lLKGWQ) that he is using.

[@SeanBZA]

SAE tooling for that banjo bolt because they are still an imperial thread, and you will never be able to change that, as it is a 1/4 inch pipe fitting. Just remember your caliper bolts, brake fitting threads and all hydraulic fittings are a metric equivalent fitting, because the old stuff was changed to nearest size. 2.5 and 4mm hex keys, very common in industrial machinery, though I will tell you that, if they do get seized fast, the easiest way to get them out is to have a few of those ultra cheap 30 piece 1/4in hex driver sets, and look for the Torx bit that will just not fit in, and tap it into the damaged hex head, so you can turn it out. Will get it out, and if you do not have a replacement capscrew, you can put it back in again with it, and wriggle it with a pair of pliers to get the bit out, making it into a Torx head. Done that very often, because you might need that machine to run right there and then, and driving to get a new one, adding an extra hour of breakdown time, is often not an option. Make a note to keep that size as spare parts, for the next visit. I go through a lot of those size, M4 and M5, as they are a common thread, and you find often the stainless steel will gall fast to the aluminium parts if you do not use a thread sealer on them, especially if they get hot. I also have the thread repair kits for those sizes in various lengths, and the extractors for the broken screws, though you really burn through cobalt drill bits doing that, especially for the 8.8 high strength variant, and the left hand thread version drill bits are stupid expensive, even in plain HSS. Ridgid do make a really nice extractor set, but sadly the lifetime warranty does not apply by me, so I have had to buy some replacement sets along the way, because I always break the smaller sizes.

[@IanHoltzhauzen]

Hello, why should we replace the engine mount bolt? I had done about +-20 vw golf gti timing chains/cylinder heads without changing the bolt and never had a problem🤔

[@HumbleMechanic]

Per the repair manual, the bolt is one time use. Now I can confirm you can reuse the bolt with no issues. But I want to be sure I am recommending people replace hardware when required.

[@sammyd7857]

A motor with so much blow by is a piece of crap.

[@Javservice]

I worked many years as a tech for Volkswagen. The carbon build up in the valves is also a problem in Audi which I also work for. And it’s cause by direct injection design. A catch can may alíviate it a little but I will not make it go away.

[@3_L_mafia]

Would this cause your car not to pass smog in California?
