First off, let me start out by saying, thank you all for the hours off strange entertainment I have had reading the large amounts of threads. Now on to my question. I have noticed a small oil leak, and have not found any spots of oil nor has the tip of my exhaust been "greasy". So I went hunting to see where the common placed oil leaks occurred on a 2.8 30v. I have found that to be the valve cover gaskets and cam seals. I also found a page on blauparts where they talk about the oil breathing system and how it can get clogged up with sludge and increase the oil pressure causing oil to leak out of the weakest spots. Here is that page http://www.blauparts.com/audi/audi_breather_hose/audi_a4_breather_hose_crankcase_hose.shtml So today I checked my oil breathing hose and low and behold I found this http://i746.photobucket.com/albums/xx108/Thunderwuss/IMAG0099.jpg?t=1289693667 now just out of curiosity I checked my timing belt and I found this "mushy" type stuff, which my dad said was belt residue... which scares me. I have 137,xxx miles so I know I'm not due for a new belt for at least another 15k miles, heres that picture http://i746.photobucket.com/albums/xx108/Thunderwuss/IMAG0104.jpg?t=1289693667 I did see oil on the driver side heads but not the passanger side heads so I am going to take a guess and say that is due to my spilling a little oil when I change it cause most of the oil was in the "4" spark plug well, but I guess its also possible that one valve cover gasket is leaking and the other is not. I am thinking about getting a new oil breathing system and replacing that, but have come here for your knowledge and wisdom. Do you think replacing my oil breathing system will stop my small leak? has anyone here ever even replaced theres?

it's def possible to have just one valve cover bad

keep in mind if you have oil leaking you really wanna do the cam tensioner seal also

I'm not sure what your using for mileage interval for your t-belt though, when was it changed last?

it's hard to tell in the pic but looks like your getting lateral cracking and if so i would look into changing it soon

I am going to say it was last changed anywhere from 80k to 100k miles. I bought the car with 122k miles on it. If the timing service was never done I doubt it would have held up. I didn't see any cracking on the belt when I was looking at it. Do you know anything about that oil breathing system?

can u get a pic of the belt without flash? it def could've lasted this long, if your guessing on when it was done i would count odds that it hasn't been

as far as the breather the hoses are notorious for deteriorating clogging, and cracking, best bet it so replace them but they can get expensive

the a6 that i was driving for awhile had around 125k on the original belt, i drove it from 100k to that point, so yes you NEED to change that belt, 99% chance it hasnt been done, if you have no proof its been done then its time to do it, while your doing the belt do the valve cover seals and the cam chain tensioner seals at the same time. the breather hose issue is very common and ussually needs to be completly replaced

When the breather system clogs up it will start leaking oil out of every little gasket on the engine. Start by replacing valve cover gaskets and breather hoses (ecs has a kit that's pretty good here (http://www.ecstuning.com/Audi-B5_A4-Quattro-V6_30v/Search/Breather/ES1899536/))

Like others have said NEVER EVER EVER assume your belt was changed. Even if the belt looks ok the water pump might not be and it is usually what makes the belt break.

First of all, way to go for reading up and searching and knowing what your talking about before you posted. Alot of the new people don't do that, and us regulars really respect those that do.

Like others have been saying, get on replacing that belt. Even If it was done around 80k, your due for another, and you can never be too safe with that belt. It breaks, your screwed.

Can you get the breather hose off to clean it up? I tried and broke mine in half. Ecs charged me about 100 bucks for the stupid ass hose, so be careful if you do pull it.

Good luck!

Thank you for all your replies. I will be going to the dealer tomorrow to see if they have any records of the belt being changed at a dealership. If not... looks like I'm dropping $400. I just always assumed mine was done because at almost 140k my water pump has had no leaks and has never made a noise. I will obviously be changing my cam seals and my cam chain tensioner seals (Thank you 99blueb5) while everything is out and open, but I am going to hold out on the valve cover gaskets and try to clean up the breather hoses and see if my leak subsides. Is there any other things that should be done while I have her face torn off?

Ok, I have a couple more pics of the belt. The guy at the dealer wanted to charge me $50 to check my timing belt because they said it takes them 30mins to remove the plastic decorative pieces.... o.0 A screw driver and 5 mins is all I need... anyways, they also said they can only check if my car was serviced at THEIR dealership. I thought that they could check if it was done by any VW/AUDI dealer, hmmm. Anyways, here are the other timing belt pics. I can see the the teeth are not rounded, which is a good sign, but I will let you knowledgeable fellows decipher yourselves. :)http://i746.photobucket.com/albums/xx108/Thunderwuss/IMAG0109.jpg?t=1289863337http://i746.photobucket.com/albums/xx108/Thunderwuss/IMAG0111.jpg?t=1289863337http://i746.photobucket.com/albums/xx108/Thunderwuss/IMAG0110.jpg?t=1289863337
