No engine mods, 40 miles daily highway driving. No racing (other than traffic!)

Out of the blue I'm getting oil smoke at stoplights from under the hood. I take it in to the dealer and after taking it apart they say "leaking valve cover seal right side and leaking cam seal". It's covered under warranty and required 3.5 hours labor. (Must be a pain to get to?)

Get the obligatory warning of 'residual oil make take a while to burn off', etc. It's been another thousand miles and I'm still got oil burning on the exhaust manifold. Going to take it in again next week.

This seems really strange to me that an engine if having seal problems at 36k. Dealer said "seals just dry out". I've been trying to imagine any scenario that could have caused this and only come up with 2:

1) Oil was possibly overfilled at the last service (35k, same dealer)
or....
2) I had it smogged around 36k just before this happened at a regular smog shop. The dips**t that ran the test revved it to 5400 RPM for almost 20 seconds before I ran over to beat the crap out of him. The test calls for 2500 RPM for 60 seconds; I saw my tach before he quit. He hadn't set up the test right and was having trouble finding timing for the computer. I don't know what prompted him to rev it so high but I was not pleased. Would high revs with no load overpressure oil?

In either case, this will likely end up fixed. I'm not too happy about having the engine pulled apart multiple times and am curious if anyone else with a V6 ran into leaky seals.......

This is not an uncommon problem on the V6s. Valve cover seals especially, though I've heard crank shaft seals are an issue more often than they should be on both 1.8T and V6.

Sorry, but VW doesn't make a dry engine at this time. The V6 is probably the worst about it.

Get used to replacing the seals every once in a while or get a different car.

And next time, when you're paying, you can bet it won't be 3.5 hours of labor they charge you. :)

That's what I was looking for; a 'yes it happens' or 'wtf did you do to your car!' answer. Thanks!

About changing valve cover seals -- I know it wouldn't be as cut and dry as doing it on my Studebaker. But if I need to to this at 70K or so, is it "user servicable"? I'm not deluded enough to call myself a mechanic -- new hoses, belts and a carb rebuild is about the most I can do. With that skill level: Avoid it, try it, no comment...?

My 2000 V6 started leaking in the same exact manner at 45K. It made a horrible smell as the oil leaked all over the exhaust manifold. To make a long story short, I have had over 6 repair attempts on it. They have replaced the valve cover gaskets (5 times) and have replaced the cam tensioner gaskets once (or so they say) - all of this under warranty. Problem is, it is still leaking and I still have the smell. The leak is not coming from the valve cover gaskets anymore, but is running down the back of the engine. I suspect the cam tensioner gaskets are leaking and that they never replaced them like they said they did. :mad:

To make things worse, I have since left the state where all of these repair attempts happened and moved to a different state. VWOA says the original dealer is responsible because it was faulty repair work, and if I want it fixed, I need to return to them. Of course, this is not possible since it is a 17 hour drive! I am still fighting this....I hope your attempt to get it fixed goes much better.

To do it right, the cams come OUT, and everything rubber in the head gets replaced.

Not for the novice.

Valve cover gaskets are not the real issue, but the cams are.

Took mine to one dealer said the cam tensioners needed to be replaced.
Got a 2nd opinion at another stealer which could'nt find the leak. took it to a German car specialist and they changed all the seals at a very reasonable price. No leak after 4k miles . I don't trust VW dealers.

could it be related to the relatively low miles you have? 36000 in 4 years, wow. I guess I spend a little bit more time in mine on average than you do seeing that mine is a 99 with 96000

Thats what I think too. Also you do need to rev your car once in a while to clear any deposits on your valves and keep the engine healthy. With the low miles I am guessing you never rev your engine enough, may be you do, I dont know. I have heard of the same problem on lot of other cars. They call it the :Grandpa cycle syndrome when you have so many failures with valve cover gaskets. Do you also have a problem with engine knock by any chance?

Good grief!

With that logic, we can expect to hear "...that's Wolfgang's (the fellow at the assembly line who puts the rumpets and muffler-bearings on) problem -- he put them on incorrectly".

Sounds like VW is taking the Bill Clinton approach to accepting responsibility.

What poop!

My leak was diagnosed as "Needs both sides cam tensioner seals". This will be covered under warranty, but just curious what the repair process entails. Is it the same process as getting to the timing belt? It's time to replace the timing belt so I'm wondering if I can piggyback some of the labor cost onto the warranty work.

The belt has to come off the pulleys, so ya, some of the labor is duplicated.

To do the seals correctly, the cams come out. It is not light work.

I'd have them throw on a new belt while they're in there.

I Think I fixed it.
I added some kind of sealant.
It's been three days, and so far it didn't smoked :lol:


I'll wait couple more days, if everything going to be alright, I will post what sealer it is. :wink:

You guys are freaking me out about the oil leaks :mad:
I have a 2001 with 21K and so far no leaks or any problems at all. Knock on wood. The car is driven usually on the weekends or may be once every two weeks. When it is driven however, it does relieve a lot of gas :oops: :lol:
