Hey guys.

I have a 2.8 ATQ. I had my VC gaskets done by a member on this forum 10k ago. They are leaking again!

I used the Blau parts premium kit. Including cam cap seals cct gasket and all.
I even got a new vented oil cap.

This person told me cap seals were un.necessary.

Question, could it be the parts or a faulty installation that's the cause of the leak?

Depends on where it's leaking. Were the nuts torqued to spec? How is your PCV system doing? Replacing it isn't terribly expensive now, with the availability of aftermarket stuff:

Walky,

They were tightened with a regular socket wrench, not a torque wrench, so that could be one of the issues. Do you know the recommended specs?

Pcv as far as I know is the original on the car, 90k miles.

I'd put my money on the PCV system.

Make sure you replace the hose that runs on the back of the engine also, from the crankcase to the intake or something, can't remember (part number 078 103 223). If you don't you could have this awful noise:

Holy shit! I have that same noise. And I thought it was coolant on the belts form when my radiator hose took a crap a while back. I'm assumint the same part or symptom woul dhold true for the ATQ?

You guys are lifesavers!

Edit: Question how would this affect the VC leaking though? too much air or pressure in the heads ?

Not sure on the 2.8, but on the 1.8t Audi specifies to use The Right Stuff on spots of the 1.8t head where it goes from being flat to going over something like the cams.

You can further see here in my technical diagram.

Just add the stuff in the areas that change from being flat, get it in the cracks, then put the gasket on, then valve cover on top of it, torque it down.

Something like that..

Next time your car starts making that noise, remove the breather hose from the passenger side valve cover. It should go away. If it doesn't, then that's not the problem.

Thanks for the advice guys, ill check everything out this weekend when I have some time.

So just to be clear the faulty pcv valve can cause oil leaks due to incorrect breathing or pressure?

Correct. If the PCV is plugged up, it can cause crankcase pressure to build and push oil out of the valve covers, etc. Your vented oil cap will help, but I'm not sure it would completely cover up a problem like that.

Now I know for a fact it's the PCV. I git the VC &CCT GASKET done with my TB @ 80k.

Prior to TB, oil leak was from CCT locations. Passenger side back and driver's side front of engine.

Post TB, leak is from front on both sides.

disconnected the breather hose from teh VC on the passenger side, that hose is definitely the issue. You guys think it makes sen to just do the entire system change? http://www.ecstuning.com/Audi-B5_A4-Quattro-V6_30v/Engine/Emission/ES1899536/ (ECS PCV Service Kit)

Do i have to do my VC gaksets again? and if so does that include CCT gaskets as well?

I would do the PCV first, clean the leaks up a bit externally, then see if you have redo any gaskets. You probably won't.

whole system kit or just the main hose?

I had a bad PCV system in my car and it ended up causing me to have to drop the crossmember and re-seal the oil pan twice because it created a leak. Once the leak was created, it had to be re-sealed.

So i guess its better safe than sorry and Im better off doing the whole system

Thread revival.
Hey guys, been traveling for work and haven't done PCV yet ;but was thinking of some alternatives to ordering the OEM plastic kit, especially since its $150

Would I be able to piece together a stainless steel line and fittings kit like the 1.8T guys do? I figured summit racing lines and fittings ;then just order the suction pump and check valve from ECS.

Is this possible, if so, anyone know hose sizes/measurements and fitting sizes, or where I could find that info?

Thoughts?

Stainless steel, eh? You can definitely cut off all the accordion parts, harvest the connector ends, and make up the rest with whatever you want. I'd suggest some simple rubber hose, but you can flush some cash on stainless steel stuff if you wish.
