Did this job on my audi A4 B6 1.8t. One of hardest parts was to open those clamps and remove rubber parts that has turned to stone becouse car is almost 24 years old. Your video realy helps. Thank You!
It looks like the hardest part of this job is just being able to get to those clamps and when you, being able to release them. Amazing how you can work through the runners of the intake manifold to get access to release clamps. Nice work Thomas!
I did this last summer, took the intake manifold off first. Made it much easier to get all the pieces of the plastic hose that fell into the oil condenser / cooler housing.
I recently replaced that plastic L pipe on my B5, it was cracked like that. I replaced it without removing anything, didn't even unbolt the coolant reservoir. I used endoscope camera to see what I was doing, a bendy Dremel attachment to cut the clamps, & a set of picks to remove the clip & hoses, I then used the camera to look into the pipe & vent hole & used the picks & a grabber tool to remove any broken off plastic bits of the pipe & clean the vent hole with a towel covered in brake cleaner. I did end up breaking the oil dipstick tube, bumped it with my arm & it just snapped off, at least it's pretty simple to replace without needing to remove anything else. I already had replaced the PCV valve itself a few months before that but was still smelling fumes in the cabin, then noticed that L pipe was completely cracked near the T fitting. I should of just did it all at the same time. But with the right tools & slim enough arms, you can do this job without taking anything else apart.
Thank you. I'm working on the same thing on my 98 Passat GLS with an AEB engine. The crankcase breather hose is cracked. I'm ordering that part along with the Tee and the PCV and a few more components upstream. Hopefully that fixes the idle roughness.
Sounds like a good start! At 22 years old, there are probably a number of things that are contributing to idle issues. Let me know if things change for the better. Thank you for watching!
@@EXOVCDS Thanks for the reply! I purchased a new crankcase breather hose, o-ring, rubber Tee and a PCV valve. That didn't fix it. But at the very least that part isn't broken anymore. The existing PCV valve looked okay. There was some oil residue on it, but i take that is normal. The rubber Tee connects up to the metal breather hose that wraps around the back of the engine and back to the front where the crankcase breather valve (?) - the hockey puck looking thing - is located. I didn't replace it yet, but after removing it, i see gunk on the inside. I don't know of a good way to see if the diaphragm in it is still good. I wasn't able to find a local source for it yet either. That's the next thing i'd like to replace, but maybe its also worth the money to have a mechanic look at it.
@@thomasng6870 thanks for the update. Have you got a scan tool? Can it view / show "fuel trim values"? If yes, what are the % values at idle & part throttle? How rough is rough? Misfiring rough?
@@EXOVCDS Its been a rough work week. I haven't been able to work on the car. I've turned it over to a local VW mechanic to have a look. I don't have a scan tool, though it sounds like i should invest the money in a the VAG-COM cable + VCDS setup. As far as roughness goes: When you release the accelerator and drop down below ~1000-1100 RPM, the car "revs" between 800-100 RPM. You can hear it go up and down for a few seconds until it somewhat stabilizes at idle. This is very repeatable. At higher RPM, the engine appears to run fine. When you do this, i can basically kill the engine if i rev it up to ~1100 RPM and quickly release the accelerator. The car has 94K miles on it. The water pump needs to be replaced (the bearings are loud); and the timing belt will be replaced as well. Maybe there is a possibility the timing is off at low RPM?
@@thomasng6870 The engine uses the throttle body to adjust idle... over time, the throttle body bore can get dirty. Cleaning the bore around the throttle plate (engine off, open the throttle with one hand and clean the inside of the throttle bore with your other hand and a moist rag soaked in brake parts cleaner or MAF cleaner) can solve low idle issues.
Yea, if you smell gas and fumes you just need to RUN! 😉... Running a 04 Passat wagon with the 1.8T which is pretty much same running here. Finally able to work on it now that it's road worthy new brakes and rotors all around and full maintenance it's time now to replace and upgrade these types of parts. Too much neglect on my "Granny Sleeper" unfortunately prior to me owning it.
I replaced all my b5 a4 pcv hoses with 034 motorsports silicone hoses. Should have changed the check valves to cause I still get the burning oil smell. Installing an oil seperater when I have time.
Check valves (unless broken) will not cause a burning oil smell. I guess if it's not allowing PCV to vent, then it could cause too much pressure in the crankcase... causing seals to leak. My guess is that the smell is from oil leaking onto the exhaust. Don't forget to check the camshaft seal behind the camshaft sprocket.
@@EXOVCDS I'm sure every seal is leaking. When I changed my spark plugs they had oil on them along with my pistons. With fresh coils and plugs. My CEL turned off and passed emissions. Came back on within a month. Plugs have a little oil on them again. It's a 2000 a4 and I'm sure the previous owner didn't care about maintenance. Very old check valves.
@@EXOVCDS I've had it since 2012. For the most part its been very reliable after doing a whole timing belt kit back then and only putting 40k miles since. Getting an 08 or 09 now I found at good prices.

I saw some oil around that part and wondered what it was. I have a 1.8t Audi and this helped - I’m smelling the fumes from that area you were talking about. Time to check Rock Auto! Lol
Thomas EXOVCDS just ordered the PCV parts today and waiting for them to come in the mail. Changing the trans filter, oil and gasket maybe in two days - 03 a4 b6 1.8t Quattro. I also have quite a few codes I don’t know where to look to fix them also such as 16804 catalyst system, bank 1 Efficiency below threshold - sporadic... not sure if it could be the cat or o2 sensor. I have a reader but not sure how to look deeper into the system
@@JourneyedAvenger The ECM flags cats by monitoring O2 sensor activity.... monitor rear O2 sensor voltage. When at cruising speeds, rear O2 should be around 600-700mv. If it cycles lean / rich (100mv to 800mv) then the cat is no good. Keep in mind that at some times the voltage will fluctuate (when cat is still cold or when the ECM is testing the O2's)... but once the engine is warm and you are at cruising speed, you want to see a somewhat steady & rich rear O2 signal.
Thomas EXOVCDS thanks! Do you know what number to put into the measuring block to monitor that? I just got a new scanning tool equipped with VAGCom and know a little bit but not a lot with it
@@JourneyedAvenger I think between 30 and 40 you'll find front & read O2 info. if your scan tool defines the fields... simply scroll through from 001 to 255 so you can get familiar with the different groups.
The long tube with arms coming off of it that’s right below the intake, what is that hose called? It’s the hose you see first when flashing a light down. I can’t find the name of that part. Thanks
Whatever is easier... it's always nice when a repair can be done more than one way. Less chance of getting bored of doing the same thing over and over. =)
@@GodardScientific you need a long screwdriver or pry bar to push down on the plastic lip / ridge above the o-ring. Make sure that the o-ring is lubricated. Tint push too hard or the part will crack.
Thanks for the video. I just replaced breather hoses and valves to my passat 3bg 2004 1.8t AWT. I think that the plastic o-ring fell into the crank chamber - can it cause any damage? It was very soft and in many little pieces so i couldn't get it out.
One question. Do you know, if you blend off the pcv pipe to the intake and let the pcv breath out in the FREE air from the walvecover, would that result in poor gas milaged?
Have you been having issues on 2.8 30v engines that have vacuum leaks from the oil filler cap? I've gotten the redesigned cap that comes with a gasket on it, and the gasket that sits on the valve cover, and always has a vacuum leak unless I push down on the gasket sitting on the valve cover. I feel like I'm missing something here that's gonna make me feel dumb.
@@EXOVCDS Smoke test. Only comes out the oil fill cap. The gasket that sits on the valve cover though feels like it's a hair bit too small to fit on the ring too for some reason. It also has that vacuum leak symptom of having a low and jumpy RPM at idle but completely smooth with any bit of throttle.
Did the customer tell you they could smell oil? Most people wouldn't have a clue what oil smells like. That was kind of a tight spot to get into but you found the issue. Nice.
I am having a crazy tough time removing the T from the metal hose on the right (towards the car firewall). Got the hose clamps loose and the T spins, but cant seem to pull it off.
Use a long hose pick tool to go between the pipe and rubber T... pull up on the tool to stretch the T. It should then come off as you force it away from the pipe with the Pick. www.amazon.com/Lisle-80380-Hose-Remover-Set/dp/B0079GPYR2/
I just cant get the Clamp of on the T hose connecting to the PCV valve. I m losing hope here, I think the only other option left is getting the manifold off. which I really dont want to do as I am inexperienced. Any tips would be appreciated. Thanks
Thanks for the quick response. I have tried that but no result, have already spent hours on it in this heat. Do you have a video on taking the Intake manifold off. I have searched the whole intrnet including your channel. cant seem to find any... thanks again really appreciate your videos
Not sure if this will help: fkh161.ca/VW/Passat/anji/ Remove what you have to remove... take pictures of items before you remove them, so you can put them back in the same place. Don't drop anything down an open port of the engine!!
Hey have you ever came across of a pesky camshaft code,the car is a 02 Jetta with the 1.8t,timing marks are aligned,replaced the camshaft senor too and no luck,any suggestions? Ecm went bad?
I've had many people tell me that they had the camshafts or cam & crank aligned correctly... only for it to not be the case. Were you trying to solve this code or did this code come up after a repair? Send TDC alignment pictures to fkh161@fkh161.ca so that I can see. Aftermarket chain tensioners can be non-reliable. OE are expensive, but trustworthy. If the engine ever had valve damage... check the cam pulley key to see if it is cracked (cam sprocket could be moving on the camshaft). Oil pressure is also a variable. Lots of things to check / eliminate as the cause.
PCV delete can fail emission inspections in certain states / countries... so be aware of that. The only benefit to PCV delete (the engine no longer receives PCV fumes in the intake) is a clean intake passage. No more engine oil will accumulate on the throttle plate, inside the intake manifold and on the valves. A catch can "catches" oil and "reduces" the amount that is fed into the intake. Venting the PCV fumes to the atmosphere via a small air filter, can cause unwanted PCV / oil fumes to get into the fresh air intake of the interior... which causes oil smells inside the car. Depending on the type of filter & the location, it can cause oil deposits / staining in the engine bay.
Remove the vacuum line from the fuel pressure regulator and check for wetness. Could be a bad pressure regulator or a leaky fuel injector. How does the engine start when warm (after sitting for 10min)?
Hi Thomas, I have an Audi A4 b7 1.8T, I have the same bad smell coming into the cabin, Also when the engine is warm, it has a hard time starting and when accelerating hard it misfires but I get no CEL, I had a look under the intake at the pcv system and nothing seemed to cracked or broken but I replaced the Breather valve anyway which seemed to be clogged, when I take off the oil cap it rattles also. Any advice ?
Oil dripping on to the exhaust manifold will cause oil smell. I use a smoke machine to find PCV leaks. I can only suggest to keep looking... look for wetness / oil moisture, that can be a sign of pcv leak.
i did all that including manifold gasket , engine gasket and exhaust manifod gasket sttill smells like oil from the area that you are working on, why, everything has been changed wtf@!!!!
Sometimes the engine & exhaust has to be washed, to remove the oil that had leaked out. Some pcv leaks are small and can only be spotted with a smoke machine.
Hello. My name is Robert. I am from Romania. I'm watching the videos you post. I would need the vag nominal values for a 2003 Passat 1.9 tdi 131 cp engine. I think somebody walked to these values with the car not working properly. Thank you very much
Shortly, I will be addressing the issue of a leaking PCV on my car, VW Passat 1.8T 2004, motorcode AWT / 3BG / 3B3, 150 PS. I am uncertain about the exact extent as I have not started a detailed investigation into where the leak(s) are located. Does anyone know the dimensions and the respective number of clamps needed? Much appreciated if anyone could give me a hint! P.S. If anyone also has tips on an affordable repair kit for the PCV, I am open to such suggestions.
I’m late to the party but god damn bro.... you make it look easy 😂 had to do this myself about a month ago, didn’t take me 2 hours, honest 🙄🤣 I also left manifold in place.
I've never done it with the manifold removed... yes, there'll be more room / better access, but more things will need to be / may need to be replaced. It wasn't that bad to do... was it (with manifold in place)? Thank you for watching!
There are many "best places".... best place is someone local, so you can see / match up the parts in person. Web order can be convenient, as long as you are sure you get the right stuff. Deal with someone you can talk to (on the phone) and who knows his stuff (VW specialty parts store) to eliminate some of the possible risks with ordering online. ECStuning.com Germanautoparts.com many many more (google search).
Guys, can i just eliminate all pcv sistem from my audi 1.8t awt? Can i just connect low and upper breather with hoses and put them below the car? I have done this on many cars before, just dont know can i do it without consequences on this engine?
Need me a GTI. What have you seen with the EA888 engines? I know the cam ladder/valve covers leak, causing the water pump to leak, and timing chain tensioners fail, as well as front cover sealant, which requires a new front cover, because you bend it removing it. Am I missing anything?
My PCV has been removed by the factory. LOL.... Just some commentary humor. I am so not video savvy. I uploaded a couple vid's of my doggies a few years back at the peak of my skills. However I wanted to send you some photos, but I think that cannot be done. VIVA the technical revolution!!!
Thomas EXOVCDS I will send the pics. My search has excluded many things. Spark, fuel, emissions, previous hacks. The only constant thing I have is a cam code and a limp mode. When I clear the cam code it clears up the idle for a couple seconds. Right back. The limp mode happens equally frequent. The one constant is if I start up the car and put it in drive many times no limp. But if I start up and drop in Reverse, always limp mode. Over and over. No other codes. It’s got to be the timing is actually off a tooth on the belt or the chain tensioner. I’m going to check the crank timing mark with the exhaust cam wheel mark. If those are perfect then it has to be the chain. Any last thoughts. Thanks Thomas.
From the PCV Box in the block? The one I used a vacuum on? Large broken pieces will stay in the bottom of the PCV box and "might not be an issue". If pieces are sitting in the round mounting area, the new "plastic elbow" won't seat / sit correctly and you won't be able to get the retaining clip to sit in place... smaller pieces that fell to the bottom of the PCV box could get sucked up and jam-up the PCV check valve. Send me pictures of the PCV box, so I can see what things look like. Click the fkh161 link in the description and then click "tool request" to send me pictures.
Sorry... Thomas. I missed some of your vids! I was travelling to Berlin for work...so this is not the time to extensively watch ;-)) My apologies!! :-)) Aaand by accident you talk about city trips here! ;-)
Loss of oil how? You notice oil dripping onto the ground under the engine? You have to add oil every 1000 miles? Bad PCV can stain the engine with oil... but not really cause an oil leak. If you have actual oil leaks / dripping oil from the engine.... clean the area so that you can see where the oil is coming from. Once you know the source, repair the leak.
Year & model? Fumes are from the PCV... unless it's oil from the valve cover that is dripping onto the exhaust. Oil consumption is probably more due to oil getting past the rings and burning in the cylinders.
If it's a 1.8T, did you replace the chain tensioner gasket as well? Could be residual oil on the exhaust. If there's smoke... follow the smoke to the source (exhaust or pcv tube)... then you can determine if it's oil dripping on the exhaust still or PCV fumes.
@@EXOVCDS Are you based in the UK by any chance ? only asking because my B5 nobody knows what there talking about near me that includes so called VW specialists because they say they have never seen one like mine before haha AEB engine
A true story! A good customer of our was always arguing with his wife over which one was farting in the car until the Son drove the car and asked the parents what the bad smell was in the car.

Use a long hose pick tool to go between the pipe and rubber T... pull up on the tool to stretch the T. It should then come off as you force it away from the pipe with the Pick.

@@EXOVCDS thanks, I am going to try this tomorrow. Will keep you posted.
Awesome skills Thomas Thank You!
Thank you for watching!
Happy New Year!
I just cant get the Clamp of on the T hose connecting to the PCV valve. I m losing hope here, I think the only other option left is getting the manifold off. which I really dont want to do as I am inexperienced. Any tips would be appreciated. Thanks
Use a long screwdriver and wedge against the clamp... if you find the right spot, the clamp will split open / off of the the retaining clips.
Thanks for the quick response. I have tried that but no result, have already spent hours on it in this heat. Do you have a video on taking the Intake manifold off. I have searched the whole intrnet including your channel. cant seem to find any... thanks again really appreciate your videos
Sorry... don't have an intake removal video. I can look for some service info / parts diagram, that's about it.
THANK YOU so much
Not sure if this will help: fkh161.ca/VW/Passat/anji/
Remove what you have to remove... take pictures of items before you remove them, so you can put them back in the same place. Don't drop anything down an open port of the engine!!
Hey have you ever came across of a pesky camshaft code,the car is a 02 Jetta with the 1.8t,timing marks are aligned,replaced the camshaft senor too and no luck,any suggestions? Ecm went bad?
Bad tensioner or stretched chain?
Thomas EXOVCDS I replaced them too,does the camshaft tensioner has anything to do with it you think?
I've had many people tell me that they had the camshafts or cam & crank aligned correctly... only for it to not be the case. Were you trying to solve this code or did this code come up after a repair? Send TDC alignment pictures to fkh161@fkh161.ca so that I can see. Aftermarket chain tensioners can be non-reliable. OE are expensive, but trustworthy. If the engine ever had valve damage... check the cam pulley key to see if it is cracked (cam sprocket could be moving on the camshaft). Oil pressure is also a variable. Lots of things to check / eliminate as the cause.
Good comment about the oil pressure. The little screen could be clogged also. Happy new year Thomas
Thomas EXOVCDS would do,thank you for your help,happy new year!
What are benefits for doing a PCV delete on a non turbo engine and would you use just a breather filter or an oil catch can?
PCV delete can fail emission inspections in certain states / countries... so be aware of that.
The only benefit to PCV delete (the engine no longer receives PCV fumes in the intake) is a clean intake passage. No more engine oil will accumulate on the throttle plate, inside the intake manifold and on the valves. A catch can "catches" oil and "reduces" the amount that is fed into the intake. Venting the PCV fumes to the atmosphere via a small air filter, can cause unwanted PCV / oil fumes to get into the fresh air intake of the interior... which causes oil smells inside the car. Depending on the type of filter & the location, it can cause oil deposits / staining in the engine bay.
Changed the oil on my bam 225 got a smel of fuel in the oil dont think my rings are bad any pointers what i shud look at
Remove the vacuum line from the fuel pressure regulator and check for wetness. Could be a bad pressure regulator or a leaky fuel injector. How does the engine start when warm (after sitting for 10min)?
hey, my project car that has 1.6l engine in it, will it be located at the same place?
Will what be where? Year, make, model? Engine production code? The more I know, the better I can help.
Hi Thomas, I have an Audi A4 b7 1.8T, I have the same bad smell coming into the cabin, Also when the engine is warm, it has a hard time starting and when accelerating hard it misfires but I get no CEL, I had a look under the intake at the pcv system and nothing seemed to cracked or broken but I replaced the Breather valve anyway which seemed to be clogged, when I take off the oil cap it rattles also. Any advice ?
Oil dripping on to the exhaust manifold will cause oil smell. I use a smoke machine to find PCV leaks. I can only suggest to keep looking... look for wetness / oil moisture, that can be a sign of pcv leak.
i did all that including manifold gasket , engine gasket and exhaust manifod gasket sttill smells like oil from the area that you are working on, why, everything has been changed wtf@!!!!
Sometimes the engine & exhaust has to be washed, to remove the oil that had leaked out. Some pcv leaks are small and can only be spotted with a smoke machine.
Hello. My name is Robert. I am from Romania. I'm watching the videos you post. I would need the vag nominal values for a 2003 Passat 1.9 tdi 131 cp engine. I think somebody walked to these values with the car not working properly. Thank you very much
I don't have values for programming, sorry.
How much do you think a shop will normally charge for something like that I have the same problem
Depends on how many parts... the hourly shop rate, currency etc. Parts alone can be over $200.
All VW audi pcv systems are failure prone. Did this have any cel lights on?
No, just oil smell.
Happy New Year & all the best to you & yours!!!!
So will this cause a oil and gas smell In a mk4 jetta with a 1.8t? I do see a rip in my pcv breather hose lol either way I have to replace it
Oil smell... if you have gas smell, you have a more serious issue.
You’re like the 1.8T surgeon. I’m going thru this job right now myself. I’m afraid I’ll have to remove the intake for clearance.
It's always better to remove more items / make more room... to make a job / access easier.
Shortly, I will be addressing the issue of a leaking PCV on my car, VW Passat 1.8T 2004, motorcode AWT / 3BG / 3B3, 150 PS. I am uncertain about the exact extent as I have not started a detailed investigation into where the leak(s) are located. Does anyone know the dimensions and the respective number of clamps needed? Much appreciated if anyone could give me a hint!
P.S. If anyone also has tips on an affordable repair kit for the PCV, I am open to such suggestions.
I’m late to the party but god damn bro.... you make it look easy 😂 had to do this myself about a month ago, didn’t take me 2 hours, honest 🙄🤣 I also left manifold in place.
I've never done it with the manifold removed... yes, there'll be more room / better access, but more things will need to be / may need to be replaced. It wasn't that bad to do... was it (with manifold in place)? Thank you for watching!
Where is the best place to get these replacement parts?
There are many "best places".... best place is someone local, so you can see / match up the parts in person. Web order can be convenient, as long as you are sure you get the right stuff. Deal with someone you can talk to (on the phone) and who knows his stuff (VW specialty parts store) to eliminate some of the possible risks with ordering online.

Guys, can i just eliminate all pcv sistem from my audi 1.8t awt?
Can i just connect low and upper breather with hoses and put them below the car?
I have done this on many cars before, just dont know can i do it without consequences on this engine?
Yes, there are many DIY "PCV delete" articles that can be found via Google search.
VW seems to have a pattern with PCV valves, the FSI PCV valve made all kinds of fun things happen though. Lol
Consistency is key!
Need me a GTI.
What have you seen with the EA888 engines? I know the cam ladder/valve covers leak, causing the water pump to leak, and timing chain tensioners fail, as well as front cover sealant, which requires a new front cover, because you bend it removing it.
Am I missing anything?
Sounds about right.... from what I have heard. Haven't seen any of those issues yet first hand.
My PCV has been removed by the factory. LOL.... Just some commentary humor. I am so not video savvy. I uploaded a couple vid's of my doggies a few years back at the peak of my skills. However I wanted to send you some photos, but I think that cannot be done. VIVA the technical revolution!!!
Things didn't work out with my Mom's car today... sorry. You can send pictures to:
fkh161 @ fkh161 .ca (no spaces)
Thomas EXOVCDS I will send the pics. My search has excluded many things. Spark, fuel, emissions, previous hacks. The only constant thing I have is a cam code and a limp mode. When I clear the cam code it clears up the idle for a couple seconds. Right back. The limp mode happens equally frequent. The one constant is if I start up the car and put it in drive many times no limp. But if I start up and drop in Reverse, always limp mode. Over and over. No other codes. It’s got to be the timing is actually off a tooth on the belt or the chain tensioner. I’m going to check the crank timing mark with the exhaust cam wheel mark. If those are perfect then it has to be the chain. Any last thoughts. Thanks Thomas.
What if you can't get the pieces out?
From the PCV Box in the block? The one I used a vacuum on?
Large broken pieces will stay in the bottom of the PCV box and "might not be an issue". If pieces are sitting in the round mounting area, the new "plastic elbow" won't seat / sit correctly and you won't be able to get the retaining clip to sit in place... smaller pieces that fell to the bottom of the PCV box could get sucked up and jam-up the PCV check valve. Send me pictures of the PCV box, so I can see what things look like. Click the fkh161 link in the description and then click "tool request" to send me pictures.
Sorry... Thomas. I missed some of your vids! I was travelling to Berlin for work...so this is not the time to extensively watch ;-)) My apologies!! :-)) Aaand by accident you talk about city trips here! ;-)
No need to apologize... we are all busy people.
You don't have to watch all of my videos. =)
Do you use new oetiker style clamps?
Charles David No... worm gear / screw style, so they can be reused.
Thomas EXOVCDS I understand the practicality, but they don't look as nice imo.
Charles David you are right. They are also more bulky. For the most part, the hood is closed... so you shouldn't see them that often! ROFLMAO

For you... anything!
Would this cause loss if oil?
Loss of oil how? You notice oil dripping onto the ground under the engine? You have to add oil every 1000 miles? Bad PCV can stain the engine with oil... but not really cause an oil leak. If you have actual oil leaks / dripping oil from the engine.... clean the area so that you can see where the oil is coming from. Once you know the source, repair the leak.
Thomas EXOVCDS no dripping on the ground. Just have to add some oil every 500 miles. Also has the fumes in the climate system
Year & model? Fumes are from the PCV... unless it's oil from the valve cover that is dripping onto the exhaust. Oil consumption is probably more due to oil getting past the rings and burning in the cylinders.
Thomas EXOVCDS 2004 Passat. We got the valve cover gasket done recently but still smells inside. Also does the cap dancing thing Ive herd of.
If it's a 1.8T, did you replace the chain tensioner gasket as well? Could be residual oil on the exhaust. If there's smoke... follow the smoke to the source (exhaust or pcv tube)... then you can determine if it's oil dripping on the exhaust still or PCV fumes.
a lot easier job on fwd 1.8t's thanls for the video tho!
This passat is front wheel drive... difference is position of the engine (longways instead of sideways).
B5.5 not a B5 right ?
Yes, technically a B5.5, but getting at these PCV components is the same for all the B5 Platform 1.8T's

A true story! A good customer of our was always arguing with his wife over which one was farting in the car until the Son drove the car and asked the parents what the bad smell was in the car.
At least all 3 noticed the smell!
Makes you wonder what the Family eats.
