Nice one... i changed twice some pcv hoses that worn early..... i will apply this next time, for the other pcv components, cuz i dont want 2 do the bypass :P

[@jrenner2402]

You saved me a TONNE of money by posting this very detailed video, I thought the install was going to be easier than the removal....boy did I have some headaches working backwards but my car is running much better now and I don't have oil spewing in to my engine bay anymore! My car: -2004 VW Jetta GLS 1.8T

[@EXOVCDS]

+J Renner Good to hear things went well. After you've done a few... things get easier.

[@henryzr23]

Excuse me J Renner, but I happen to have the exact same car and I need to do this job as well; you think you can tell me what was the kit you bought for your maintenance project?, I´m a bit hesitant about what to buy as I've found that the hose setup for this car changed since 2004, many thanks.

What's your favorite engine to work on? In what platform? And what's the one vehicle that makes you cringe when you see it pull into the lot? Every technician has at least 1

[@EXOVCDS]

Touareg's come to mind... but then again, it's probably because we don't get that many. I don't like anything that I have not done / worked on before (or have seen more than a few times). So I guess if I worked on them more often, then they would also come off of my list. I like all (up to 2005) 4 cylinder engines... everything newer has too many gadgets / parts attached under the hood. Again... the more I work on the stuff, the more comfy I guess I will be. We don't do anything & everything and we don't see anything & everything in the shop. We are mainly a PM (preventative maintenance) shop... and seem to get more 4 cylinder customers than anything else. I used to like rebuilding aircooled engines (when I first started, we saw lots)... now a days, it seems that brakes, clutches, oil changes, timing belts etc keep us busy.

[@MrErikw26]

Any jeep up to 2005, Chrysler did not pay attention designing that that. Take the steering box out to remove the radiator that always crack. And like like you, anything I haven't seen/done before. Timing belts on Honda v6 can make me cringe. Love working on Ford, and Hyundai. We are mostly a PM shop as well. We don't see or fix everything and anything. It gets interesting though

Thank you for watching!

[@edwardgodoy3684]

Thomas EXVOCDS what is the part you removed and put on your work table 4 minutes into the video ? Great video

[@EXOVCDS]

At 3:54 ? That's the vacuum solenoid bridge or board. Vacuum solenoids for the Secondary Air Injection and for the diverter valve.

[@adub4279]

What tools were you using at 9:30? I’m having trouble getting the metal part of the elbow tube out and that’s the only thing that’s stopping me from completing the fix

[@EXOVCDS]

Something like this: www.amazon.com/GearWrench-84061-Panel-Remover-Black/dp/B007QV4L1A/ Twist the crap out of the metal ring and then remove it. Don't forget to vacuum out the / broken bits that fell into the breather housing.

[@jesperqwerty8481]

I just tried to replace the elbow hose, sadly it waa already broken by the joint and the plastic all fragile. While pulling the metall ring out, alot of pieces fell down that I did not manage to pick up with any tool I had, which left me quite devastated. But after googling around and founs you video, I will try to use our Dyson Vacuum with a smaller hose, HOPEFULLY it will get all the pieces out. If not, I'm screwed and have to take it to a mechanic. Passat 1.8T, AWT -04.

[@EXOVCDS]

There's a metal gasket between the breather housing & engine block (part #10 in the following link / image). Anything that falls into that PCV hole, will sit at the bottom of the breather housing. The gasket has slots that prevent stuff from falling into the engine / oil pan. A narrow vacuum tube should be able to suck up what fell in. Thank you for watching! img.7zap.com/images/oem/vag3/VW/Bilder_zgd/194/194115500.png

[@EXOVCDS]

The 3 oval slots are the pcv breather holes for the crankcase. The other holes are covered by the breather housing & engine block. Oil passages.

[@keirthomas3197]

You removed a unit which you placed on the bench. Has some hoses and what looks like a solenoid. Can you tell me what that does please?

[@EXOVCDS]

Pcv components...as the title says.

[@ar2crypto774]

damn that's a drive

[@jacobl1524]

The assembly of hoses that you removed at 3:50 is it possible to repair those if 1 joint leaks? Or do I have to get new ones?

[@EXOVCDS]

Some of those hoses have special bends in them (the hose was "molded" into that shape). If you try to replace one of those hoses with a regular hose, the hose might kink and not pass any air. Otherwise, any hose that is straight(ish) can be replaced with an equally sized hose.

[@johnarredondo6825]

After changing my pic valve on my VW Jetta 2003 than it started knocking not sure if I put the hoses in the right place?

[@EXOVCDS]

I'm not sure either... better double check what you did.

[@mmafighter6355]

How would I install this way on a TT 225 bam I've got a pcv valve inline to run back into the nipple on intake most block off, but still not got the correct suction on my oil cap, it's like it's a pulsating suction it's strange

[@EXOVCDS]

The crank case has pressure pulses... that's normal: instagram.com/p/ywFjz7FDfW/?igshid=YmMyMTA2M2Y= (Press play). If your pcv has been modified... install all factory components.

[@ivanmiranda426]

I just got a 03 gls 1.8T and the breather hose is not in place. At 6:10 you removed a clamp and I don’t have that on my car. Is anything else supposed to be holding it? Inside the hole ?

[@EXOVCDS]

It's a "C" clip... the housing has 2 slots for the C clip to sit in. The C clip is what holds the plastic elbow in the housing. If there is no C clip, then the elbow should just pull out. Over time, the rubber seal (at the base of the elbow) can get stuck to the housing making it difficult to remove the elbow. Breaking the elbow into pieces and picking out the pieces from the housing is sometimes necessary when trying to replace it.

[@mgs090110]

Great video, the crankcase breather is putting up a real fight with me, disintegrating and the stupid copper part of the breather is now stuck in breather hole with disintegrated rubber around it. I have also managed to crack / snap one of the solid vac lines that are under the metal piece bolted to the inlet with x2 5mm Allen bolts. Oh and the 10mm bolt that holds the air pipe to the underside of this is rusted solid. So.. any ideas on part numbers for the hard lines and I'm thinking it may be an inlet manifold off job to gain enough access.. grrr cars lol

[@stuzman52]

Hey Thomas. On that very last item that you were removing, is that the PCV valve? If so, that's a lot of stuff to take out to get access. Those radiator pick pliers looks pretty good at removing hoses. Nice video... 👍

[@EXOVCDS]

stuzman52 The last piece that I used the long needle nose pliers on? That was part of the PCV Elbow that connects to the 2-way check valve (PCV valve)... the PCV breather valve is up at the intake hose between the MAF & the turbo. It is round and has a flat top. There're several check valves that control PCV flow... so I can't say which is THE pcv valve. LOL

[@Kidblurr02]

what tool did you use to get that broken breather hose out? im also worried about debris falling in.

[@EXOVCDS]

Debris falling in is not an issue... just vacuum it out. Use whatever you can to break & remove the pieces that are stuck.

[@ricardoj.6970]

Hi Thomas, can a bad PCV valve cause oil burn in boost? my passat 1.8t smokes a litle when the motor is hot and when i hit the gas after a stop signal.

[@EXOVCDS]

If pcv components are older than 5 years, replace them. If the problem continues, valve stem seals or turbo are leaking oil.

[@blurr1163]

At 1:08 what is that plastic hose called again, I accidentally closed the hood on in while it was hooked up to the bungee cord and it snapped lol

[@EXOVCDS]

It's an air tube for the secondary air injection.

[@Douknowgregg]

Hey so I've been getting an check engine light that has emissions workshop come on the dash on and off for months it comes and go as it pleases and has been off for a month and randomly came back two days ago it's never been a problem before except that my inspection is due in a month and I need to be able to pass emissions. Any idea what could cause it to be going on and off so infrequently?

[@EXOVCDS]

The fault code will tell you... could be a number of things. Why guess when you can scan it and read the code. Even if the light is off, there might be a code in memory. If the light is off for the inspection, it might pass. If the light comes on before the inspection, read the fault code and let me know what it is... then I can help.

[@mcrampton1]

Would this procedure be similar for a 2002 MK1 Audi TT 1.8T? I am having idiling issues and think that I have leaks in my vacuum system and have oil leaking out of the engine too. Thanks for the video.

[@EXOVCDS]

Yes... similar pcv design / issue.

[@CodemasterRob]

Hey Thomas, I'm video hopping here but I'm not seeing one of these for an AMB 1.8T found in my B6. Off the top of your head, are there any possibly brittle parts that would make doing it from under the intake manifold a risk, or would it be fine?

[@EXOVCDS]

This video shows most of the common PCV parts (under the intake) that fail. kzbin.info/www/bejne/qJvHhZl7icpoes0 This video will give you an idea for removal (you will have more room on your car): kzbin.info/www/bejne/lZOlZKGPZbOchpo The Jetta / Golf PCV components are similar to yours. I always leave the intake in place... some guys remove the intake (takes longer, but you have more room).

[@EXOVCDS]

LOL...I replied via my KZbin comments page and didn't realize you were watching / posting under the video that I linked. The first link applies to your car though and gives you can idea of the components.

[@Joe_Rebel]

I'm getting low MAF readings even after cleaning it, and low boost. I've replaced SJP, the 3-way check valve next to it, DV, lots of hoses under the manifold, and made sure my N80 is working along with a new check valve after it. Cold start is a bit rough but, no high idle. Also I can feel blow by pulsating out of the oil fill hole when I remove the cap during idle, and I hear a quiet hissing sound under the intake manifold which I can't track. Do you know if it is PCV, PRV, or maybe a leak somewhere else? Been trying to track down this problem for months and it's really bothering me. Thanks

[@EXOVCDS]

Normal oil filler cap dance at idle: instagram.com/p/ywFjz7FDfW/ Smoke test the engine for leaks... if you can't see the leak, smoke might help find the leak / the source. If you don't have access to a smoke machine, remove the intake manifold so that you can see all of the PCV hoses & plastic tubes.

[@GuZtavo11]

Thomas EXOVCDS I have a 2001 jetta 1.8t. I've noticed that smoke is coming out of oil filler cap and oil dip stick at the same time. Car doesn't run bad. Do you have an idea of what the problem could be? Thanks in advance

[@EXOVCDS]

Depending on engine & ambient temperature, it is normal for the PCV system to smoke... when removing the oil filler cap or dipstick tube. If it smokes as soon as the engine is started (cold or warm), then you might have piston ring problems (compression blowby). Does the oil filler cap dance when you leave it loose? instagram.com/p/ywFjz7FDfW/ Press the play button.

[@EXOVCDS]

***** The bits can't fall into the oil cooler... just the block PCV vent chamber. I'm sure that's what you meant. Just clarifying for others that might be reading this.

[@rajsoni3603]

Thomas EXOVCDS what's the tool your using at 9.27 called

[@rajsoni3603]

Thomas EXOVCDS thanks for replying. really struggling to get the last bit out doesn't seem to move

[@EXOVCDS]

You pretty much have to break / bend the piece to get it out... then, use a vacuum cleaner to suck the broken pieces out of the PCV chamber in the engine block.

[@henryzr23]

Hi there Sir, excuse me but I have a vw jetta mk4 1.8T 'late' AWP and I´ve been told that the AWP engine has a different hose setup since 2004, could please confirm me if this DIY is for the late AWP version or the early one? (99-2003), thank you very much for your time.

[@EXOVCDS]

The process is similar... just the parts are different. Buy the parts that are correct for your vehicle and then follow this video... as a general guide. A parts store that specializes in selling VW parts, will sell you what applies to your engine. If you would like to check for yourself, you can do so by using this online parts catalog: volkswagen.7zap.com/en/usa/jetta/jem/2004-270/1/ Select the vehicle, year and then Engine 1... look for "ventilation for cylinder head".

[@whitey1594]

The piece that u attached to the bungee at 1:15 what is that called?

[@Pablomcdubbin]

I dropped a small piece of plastic from the elbow inside..i tried to vaccum it out you think itlp clog something up or the pick up tube filter will hold it back

[@EXOVCDS]

There's a gasket between the block and the pcv / oil flange housing. Most likely, the piece will stay in the housing (#1 of following image). Yes, worst case, it will get stuck to the oil pump pickup tube screen. img.7zap.com/images/oem/audi/Bilder/194/194115500.png

[@Pablomcdubbin]

@@EXOVCDS thanks for the reply and photo..I was worried it would get sucked up and lodged in the turbo..if worst case it gets stuck in the screen thats not bad. I can drain the oil see if it comes out or drop the pan. Id say odds are its going to be pulverized by the crank if it makes it that far lol

[@V10PDTDI]

It's a good time to do the thermostat if the car needs it usually I go with the scan tool for a test drive and see if the temperature reaches at least 90 deg C. Before taking it apart theses days I like to offer the silicone kit the only thing I seem to get issues with figment for 2004 and 2005 car one hose seems to be too small and I have to put a stock rubber hose. Don't you think that they made too many of theses parts for the 1.8 T engine. engine codes years models etc it gets confusing.

[@EXOVCDS]

V10PDTDI Our customers are usually of the "only do what is needed / what I am in for" type... meaning that once we tell them they need more (even though it is easier & cheaper to do while we have everything apart) they usually pass on the suggested repair, since there are no current symptoms to what we would like to add to the repair. Yes, those 1.8T's have way too many versions & part!

Hello Thomas quick question why or how would coolant be getting in the intake threw intercooler on a 1.8t jetta im loosing coolant every few days i have to put coolant in the bottle and engine stumbles from coolant thanks

[@EXOVCDS]

You verified that coolant is in the intercooler? The turbo is oil & water cooled... it could be that the turbo is leaking coolant into the intake. I have not seen this happen before. Are you sure that there are no external leaks? Coolant flange at the side of the cylinder head is a common leak source... as is the water pump, radiator and heater core flanges.

[@jasoncameron34]

@@EXOVCDS I took the hose off the throttle body and it was wet with coolant not alot but had a film of coolant.

I did a compression test all 4 are 120 not great but the same. Its weird once car cools down i take the cap off the coolant ball its like theirs vacuum because the coolant comes rushing back in is that normal? Thanks for your help i really appreciate it

I have a 2003 VW Jetta my engine shake every time I start it for the day. Once the engine is hot the shaking stops. Could it be the pcv ? It has not yet turn off on me while driving

[@EXOVCDS]

Shaking as in running rough? Is the check engine light flashing? If it is, then the engine is misfiring... and that could be due to PCV components that are bad / broken. Open the hood and listen to the engine... listen for hissing sounds (air leaks). If the engine is not misfiring, it might me shaking due to bad engine / transmission mounts. Which engine? 1.8T? Check for fault codes (even if the check engine light is not on) and also check "fuel trim" values (if the scan tool is able to read them).

[@kostasbakos749]

May i ask a question? I have the same engine and i have a fault code P1176. Is that hoses the reason to showe this fault code? Thank you

[@EXOVCDS]

Broken PCV hoses usually set a different code... I can recall ever running into P1176. Code info can be found here: wiki.ross-tech.com/wiki/index.php/17584/P1176/004470 Checking PCV components would still be part of "checking intake system for leaks'. Also check the exhaust for leaks (ahead of the rear O2). If your scan tool can view "fuel trim" values... check those, as they can point to a leak before or after the throttle body. MAF sensor, cleanliness of throttle body bore, coolant temperature sensor and even correct thermostat operation can play a role In fuel metering / O2 sensor operation. Unfortunately there's never just one cause for a specific code... well, some codes have specific causes.

You can eliminate the PCV... but you have to keep it open at the engine with a small air filter, so that the crankcase can breathe (not build up pressure, which causes oil leaks). Google Search "1.8T PCV delete".

Thomas EXOVCDS Enjoy your videos and subscribed. I wonder if you could help me where to start with my jerky 1.8t AUM Golf/Rabbit 2002 model. It jerks from cold at low revs (under 1500 rpm) like a mild kangarooing. You can feel the power almost doing a little surge and then cutting out. It's pretty much ok once warm. Is this likely to be a vacuum leak? If I drive fast the power and boost seem fine. I've cleaned MAF, renewed N75 valve, new diverter valve, cleaned throttle body but only allowed car to reset that by waiting to start the engine with ignition on for a minute. Where should I check/renew next? Pcv hoses, pcv valve or throttle body alignment? Something else? Thanks for any advice!

Hello Sir.I have a 1.8t jetta 2002 and im getting a lot of air in the engine. my oil cap is dancing on the cover when unscrewed.

But Im still getting lots of air in the engine. any suggestions?thank you

Bro these cars have fixed alternator pulleys, not freewheeling ones, and that doesnt mean they are bad.. The car still runs smooth, as it is supposed to. The freewheeling alternator pulley can reduce vibrations when a heavy mass alternator is installed. These are fixed from the factory.

[@EXOVCDS]

Bro... not all. As can be seen at 0:13, only clutch pulleys have plastic covers over the face of the pulley. A non clutch pulley does not have a plastic cover... and in that case, you will see the 24mm mounting nut for the pulley.

Performance loss how? Just lack of power or is clutch slipping? wiki.ross-tech.com/wiki/index.php/Fuel_Trim_Info Are all the splash guards in place in the intake camshaft? How many km's? As engines get old, they will have more blowby gasses in the crankcase... when then goes through the PCV system. Check for excessive oil at the base of the intercooler at every oil change. Check the turbo shaft for excessive freeplay. Check engine compression & leakdown and the spark plugs (to see if all cylinders behave the same). How much oil do you have to add at every 1600Km? "I think" VW says 1/5L for every 1600km is ok.

[@EXOVCDS]

If you don't have oil leaking on to the exhaust, then the only place "oil smell" could come from, is from the pcv fumes. A good sniff around the engine bay while the engine is running, should result in finding the cause. Pcv fumes will also cause smoking... an aid in finding the source.

[@GiorgioJeep05]

I have just completed the procedure you described in this video, if the smell has gone away by just replacing these plastic stuffs, I'm going to be extra happy... Otherwise I'm thinking it could be the turbo.

[@EXOVCDS]

Higher speed / air flow through the radiator can push PCV fumes in the engine bay towards / into the fresh air intake... otherwise, if oil is forced out because of higher speeds (engine) from some place... once you smell it inside the car, pull over and have a quick look under the hood.

[@ninjakeyon123]

What up og would a clogged pcv system cause a oil leak and that last piece u took out mines is completely broke in half thanks for the great vids u do a good job

[@EXOVCDS]

Yes, if the PCV system / fumes are not vented (into the intake system)... pressure in the crankcase / oil pan will increase and oil leaks can develop. It's a good idea to check / replace all those plastic PCV components every 5 years or so... or replace broken plastic pieces as soon as you spot them.
