Will be doing over this weekend, followed your advice and bought a good quality baffled catch can... Also bought reinforced 19mm oil hose & the other bits. Fingers crossed now really haha.

[@Mikelectric]

hey, i did this this morning thanks to your vid, i was on the fence but ur vid made it clear

[@tandcris97]

It was unclear for me, thanks a lot !👌🏼

[@patrickmiller6474]

Nice job looks very neat

[@mrsmith4355]

Very helpful videos I wish a saw before hours of struggle 😂👌🏾

[@ricardogomezguerra4092]

great video man

[@kilgallon_savs4803]

Brilliant video, I bet this help a lot of people out. Top work keep up the work 👌🏻 on VAGS that is 😉

[@RedlineRevs]

Ryan Kilgallon thanks taking the time to comment. Have much more planned for the channel, it's just a matter of finding time.

[@kilgallon_savs4803]

Redline Revs alright dude, you know the L that come off the intake, what size is the pipe as going to buy a bung instead of a screw 👍🏻 cheera

[@RedlineRevs]

Ryan Kilgallon hey, sorry I don't know the measurement for that piece. I just screwed a bolt into mine. Let us know if you find out what size they are.

[@silestanix]

Have done this now, definitely much better than smelling the damn fumes! Thanks for the upload man.

[@RedlineRevs]

H Singh yes paaji, good work. Glad it helped and thanks for coming back to comment G.

[@pearldrums92]

Where exactly does that outlet from the catch can plug into on the turbo inlet?

[@RedlineRevs]

All the parts required are listed in the description of the video. I've used cable / zip ties on some of my connections because I'll be coming back to this and changing the cheapo catch can for a better one. Use jubilee clamps instead to ensure everything is tight.

[@CarlosDaniel-wl2iq]

Thanks for being the first person to put a decent video about doing this. What size are all your silicone hoses you used for this?

[@RedlineRevs]

Carlos Daniel thank you for taking the time to comment. As in the description you need 19mm internal diameter oil resistant hose to delete the pcv system. If you want to delete n249 valve and change fuel pressure regulator lines as I've shown in another video you need 4mm internal diameter pipe for those.

[@chrismawa]

Great informative video. I have a Golf GTI with the 1.8T AGU engine. Will the procedure be the same?

[@jayrobinson5818]

hi mate I've got a mk4 1.8t aum engine. do I have to take out the combi valve to delete the pcv and add catch can? not sure about what I'm doing with the 3 hoses that go into the end of the metal plate in front of the manifold

[@MRFROSTSHOW]

My son has a 2001. It was pretty cobbled together under the hood when he bought it. It pushes oil out under boost. Will sit and idle all day just fine. The "hockey puck" is gone. Seems to push the oil out of the oil fill cap. We've changed it and the pcv and it still does. Any advise? tia

[@jasonthrush4598]

Hi, where did you get the 19mm hose and T from? Looked on ebay and couldnt see it.

[@fabiogomes6487]

Hi. Do you have use one way valve to brake servo? Thanks

[@johnmar1622]

One question, can the filtered oil at bottom of the can tip back to dip stick holder hole.

[@joeyanderson9886]

That hose that connects to oil cooler housing - it has broken off when trying to remove it.. I knew it was going to crumble as you said and I bought a new one but didn't think part of it would be stuck in that area, I don't know how to remove it as it's quite tight in . Do you have any ideas? It isn't supposed to twist a certain way is it?

[@g-track5065]

what is the fuel regulator hose hook too if you get the 034 delete breather awm 1.8T?

[@martinsimmons4093]

where did you get the red pipes from mate? Cant find red anywhere =/ Thanks for the vid, light bulb moment from this lol

[@vinnyp8574]

Hi there have u still got on the cranck case valve like the blow off valve on the intake connected ?? Or just straight pipe to the intake to the turbo

[@johnmar1622]

10/10 thanks for the video, Please tell me if this is possible, at 2.04, my L pipe is broken and even i removed the clamp on the crack case, i still can not remove the old plastic brass bushings. Do you think i can block that hole. And the 19mm on the top rocket cover goes thru oil catch can and back to intake. Is this feasible??? thanks

[@richarddwaine3564]

Hola, eliminaste la manguera que va del cople que va del portafiltro al múltiple de admisión hermano?

[@briancoakley1524]

Does this mod cause a check engine light? I have a 2016 Passat 1.8L turbo.

[@user-dq5pk6km6r]

In connecting in this way you are applying full turbo suction to the crankcase. It would be better to install the catch can immediately after the crankcase one-way valve, with both the one-way valve to the inlet manifold and the regulating valve/"hockey puck" to the turbo intake connected to the catch can outlet.

[@k114NS]

Hi mate got 2007 golf gti with pcv valve delete and oil catch can the car dose Smoke alot at idling but when you start driving it disappear

[@d.i.yautomotive2212]

So what did you do with the pvc valve??? That's what I want to know cause I'm having a hard time trying to figure out how that works... if I take the pvc valve out and run it straight to the can and valve cover it would run like crap

[@fabiogomes6487]

Where its going the pipe from outlet catch can?

[@mrsmith4355]

You will definitely need a new crankcase breather pipe and I would just get complete with spare clip Just in case you loose it somewhere in engine bay like myself & also round seal cause mine went totally melted,its a real nightmare to get out as he said after years of welding into place by heat oil & old age rotting wow,good luck😫👍🏾

[@MFullaStyle]

Where did you get the 3/4 fittings ??

[@colindickenson642]

Hi redline revs awesome advice on various mods on lcr's I've done a few of your modifications on my LCR with no problems at all really happy with results so far 👍 next week I'm going to attempt to do an oil catch can looks pretty straight forward to be fair one question I want to ask you bud I've heard mixed reviews on removing the hockey puck some say you need it for controlling the back pressure and that it could damage the engine if removed & some say it's fine with out it ? I'm stuck on this one I just wanted your opinion on this have you had any problems at all or heard of any issues on this ? Thanks redline

[@matk22]

I know this is a year on... but the hockey puck is on the inlet side so there won't be any back pressure. When the turbo is on boost there will be negative pressure in the intake pipe. Hope this helps any one that has read this with the same question.

[@danielholbea]

Hi ..can i do this on mk4 golf 1.6 16v bcb? Cheers

[@peterkou2682]

The t joint will have dirty gas back into the top cover ?

[@genuinestyle4872]

this is a 180hp?? with wich turbo? k03s or k04? thx

[@PetruFilip_ptm]

u have more photo with the vacum???

[@dieseld4281]

What does the pic delete do for the car

[@gsus9287]

top man, very helpful videos! ive got a 225 BAM TT if you ever wanna do a comparison video

[@RedlineRevs]

GSUS thanks for your comment and yeah I would be up for doing something like that. Where are you based?

[@Barbarbarclay]

Hey Redline - How'd you go from elbow into oil resistant hose?

[@Barbarbarclay]

dont worry i've found it - www.ebay.com.au/p/Engine-Crankcase-Breather-Hose-VW-Seat-AUDI-SKODA-06a103213f-EAP/750324828

[@jayaez3887]

What is the part number for the item you mention replacing in at the 2:09 mark. I don't see the part#. Thanks and great video! Liked.

[@emcfarlane1591]

Good video simple enough going to do it to mine now I've watched this what did you use to connect it to the tip though?

[@RedlineRevs]

Khai Elliot thanks for commenting. I had a used red silicone TIP which already had a 19mm straight pipe connector where the standard pcv system would lead to the TIP following the 'hockey puck' accumulator valve. If the original inset for PCV valve into TIP doesn't haven't that just get a straight pipe connector, should be 19mm, and clamp with jubilee clamps.

[@kashv2500]

Hi mate, good video. Do you get any oil smell in the cabin with a catch can setup?(windows open and closed)

[@levimoffatt680]

I’d say he wouldn’t because it’s plumped back into the intake if you vented to the atmosphere I’d say you would

[@johnmar1622]

awesome, i got same car as you , one question can i use exhaust fiberglass buffor??instead of steel mesh?

[@RedlineRevs]

Great cars, thanks for commenting. People have used the steel dishwashing things and they've worked well. Not sure about the fibreglass I'd stick with what's been tried and tested myself.

[@swannyswanson7398]

How'd you get that orange hose?

[@edgarrodriguez9422]

Do you have a lot of blow by ?? I noticed ive had to replace 3 valve cover gaskets cuz it might need more vaccum in that system maybe a one way check valve that would also connect to the hose after oil catch can?

[@martynemery5299]

Did changing your valve cover gasket sort out the blow by issue you had?

[@lhgof7002]

Hi redline revs !! Sorry I didn't reply to your comment on the other video I lost it some how !!! Have a few questions about the oil catch can and other things is there any way we can private message? Cheers mate top work !!

[@mmafighter6355]

Have you removed your hockey too?

[@SizeableBush]

Hi I need to do this to my car I’ve found all the parts on eBay, it’s hard to see what you used to mount the catch can, do you have to drill a hole? What bracket did you use etc?

[@RedlineRevs]

Sizeable Bush sorry forgot to mention how i mounted the catch can. It came with a bracket and I heated a screwdriver then pushed it through the battery cover housing to make holes for the bracket.

[@SizeableBush]

Redline Revs thanks for he reply mate I’ve already done it now!:)

[@ivanmoreno5374]

Qué medida es la manguera que se usa para esta mod

[@user-ok2vd2vs8s]

What mm are you’re vaccum pipes

[@LookUpTheKalergiPlanWhitePeeps]

@ 2:10. . . I HATE that damn pipe with a purple Barney passion! Lol. The very lowest part of that ridiculous brittle plastic pipe that goes into the block had pieces stuck in the block itself, I had to fish it out with a flat head screwdriver and then used a vacuum cleaner with a homemade attachment to get any fallen pieces out of the hole. I have a 2004 B5.5 Passat GLS, of course with the 1.8T, mine is engine code AWM, Wheat beige with beige leather. My car is 4 MOTION (Audi's Quattro drive train with famous center diff) and is mated to a 5 speed manual transmission. It's a unicorn here in the US. It only has 114,500 miles. I *LOVE* *LOVE* *LOVE* my car. I've replaced more parts on this car in 4 years of ownership than I've replaced on every car I've ever owned *combined* ! Most were Japanese, 02 Camry SE V6, 05 Corolla XRS, 96 Mazda 626 ES V6, 1988 Mazda 626 LX and many more, all cars were manual except the Camry. I bought my Passat because my brother once owned a 1988 Audi 90 Quattro 10V, light Beige with blue leather. (I also bought my Passat as a nonrunner for $750 dollars and since purchase, have just breached the $5,000 mark in total dollars spent.) Of all the cars either of us have owned we have the fondest memories of when we were young driving his 5 cylinder Quattro with locking rear diff. That's been about 25 years ago now. I'm now 48 and little brother is 44 and since those days we've both been through hell. . . so hopefully, if everything goes well, in the next few days I'll be purchasing a low mileage 3rd gen EA888 2018 Audi A4 Quattro with the 6 speed manual, the last year of any stick shift Audi sedan here in the US and as such, another Unicorn and when I do I'll be passing my treasured Passat on to my little brother, so he can make more memories. I've already replaced the timing belt, water pump and peripherals along with a new Victor R, MLS head gasket in the driveway with hand tools. Thanks so much for the video, I enjoy watching any content about my highly celebrated 1.8T 20 valve engine. I'm unsure if I'll do the delete yet but probably will just for my brothers sake, because he isn't mechanically inclined like I am, so I want to eliminate any and all parts with the potential to cause issues. Thanks much for this!

[@jafinjohn7367]

Got a question I got the 1.8t on my audi tt. Just installed a catch can and a pcv delete. I'm still having blow by also there is milkey colour in my catch can.

[@lilburnzee]

Jafin John I get the same thing in my 1.8T AMU TT. My hoses are ran pretty much identical but I getting some crazy blow by on a freshly built motor. (I have the ECS Tuning Baffled Catch Can, and it fills up with the milky color water your talking about in 3-4days.) im honestly considering trying to repurchase the 034 kit again for our cars and hooking up the PCV Tee back into the vacuum port on the intake manifold, but leaving out the “hockeypuck” or PCV Regulator to see if that helps. If you figure out the problem with yours please let me know and I will try to do the same if I make any progress.

[@Koetan4]

Condensation. Move your catch can to a hotter area in the bay and will have less water

[@androidloid2191]

can you do this to a 2.3 V5 engine or any NA engine?

[@tt-rs1457]

Of course.....for the VR5 and VR6 it's more simple.....

[@ImranKhan-dk8bo]

I could do with coming to you do delete n249 for me ?

[@RedlineRevs]

Would be happy to help you can message me through insta @RedlineRevsTV

[@kdotktimetopurge8549]

Can u tell me them.sizes of all pipes please

[@carterandrea1994]

hey do i have to connect the PRV (hockey puck thing) back to the T I P ?

[@carterandrea1994]

my hose broke today and i cant find a replacement i don`t have the Y split i have single hoses that run from a metal line, i just connected the PRV back on pluged the hole in the T I P and put a little filter on the open end of the PRV (hockey puck thing ) is that ok to run for now until i find a new hose on the scrap yard ? P.S: I have an AJQ engine if you need this info

[@RedlineRevs]

OL BAG it isn't ideal but probably okay as a temporary measure.

[@carterandrea1994]

Redline Revs k thx love your vids

[@ryszardwitek2563]

nice mate i juat wanted to ask please what happens with the hocky puck valve do i leave it going into the intake? thanks

[@RedlineRevs]

ryszard witek hi, you can throw away the hockey Puck as the oil catch can will take over its job.

[@azman29810]

You need to leave that hockey puck in between the turbo intake hose and catch can other wise you create back pressure in the rocker cover and damage the engine, unless you vent the catch can to atmosphere. That’s what it’s for trust me.

[@Sublimewales80]

Hey.. Could you tell me where you got the pipe from please

[@RedlineRevs]

Sublimewales80 ebay 19mm Id oil resistant hose on ebay. Don't get the soft one like mine it has subsequently split in a couple of places and I've replaced it with REINFORCED / BRAIDED hose which you should look for.

[@Sublimewales80]

Redline Revs cool thanks.. I will have a look on ebay. Been thinking about doing this for a while

[@FalkensteinSoma]

Is engine better than before? Is there any change?

[@RedlineRevs]

Soma Falkenstein my pcv system had splits and leaks in it which were causing me to loose boost. Since doing this the car is much better to drive and all the pipe work is simplified so future boost leaks will be easier to find.

[@FalkensteinSoma]

Thank's :)

[@alesiodonalpachino740]

nice)

[@mmafighter6355]

Guessing you don't know this, but you should keep the pcv valve in by routing another hose back too the intake nipple you blocked off, I done mine how you done yours and there was too much pressure in my crankcase smoke out of dipstick tube and valve cover

[@Becker_ga]

Hello mate, can you help me out? I've rerouted mine as shown in the video have the same problems as you cited, would you be able to send me a picture for better clarification of how should i route it? Sorry for bad english.

[@dteague7037]

my engine is in the other way so how can i do that do i have to take off the plentum?

[@RedlineRevs]

D Teague hi, which engine do you have?

[@dteague7037]

1.8 T i have a 2002 audi A4

[@RedlineRevs]

Should be exactly the same engine just positioned differently. I don't have any Audi engine to explain exactly the differences I'm afraid.

[@himaforlove]

👍👍👍👍👍👍

[@dollydehart4813]

How's it run without the pcv vavle

[@RedlineRevs]

Dolly DeHart it runs perfectly well without the pcv valve. And of course if your valve was leaking like mine you will eliminate boost leaks and have a better running engine.

[@MrRochaAndrew]

Please, can someone tell me if I delete the PCV system, will my check engine light turn on?

[@AudiGang413]

No

[@Darcstartv]

Removing pcv removes the assembly to help the brake booster recover quicker so is not the best idea. And removing the puck PRV completely is also a very bad idea.... now your turbo can suck from the cam cover and the PRV isn’t there to stop that which is what it does. Sorry dude so much is wrong in that. The PRV needs to be there last point into tip, catch can is fine before that valve! N249 delete is an anti lag device so removing that is also bad advice from the internet.

[@theonlynafester]

Hmm.. an oil leak over the battery seems like sort of a bad idea ngl

[@gerryr1893]

What a mess

[@adriandicu]

You speak much and don't say anything. Definitely that catchcan isn't installed well. It will get full of oil which won't be recirculated into they bay...

[@matk22]

Could you make your own video with this guide so you can show us how it's done. He spoke about everything you need to do amd explain what each part does and where it goes. So not sure what video you watched.
