Hi guys,

My car has an oil leak in front of the engine.

The car has 76k miles with 3.2L 2008.

I suspect the valve cover but 'cause there's also an oil pool on the top of the engine I'm not sure where it's coming from. I feel a little bit of vibration from the cabin but Audi told me this engine tend to vibrate.

Here's a schema of what I see :



Thanks for your help

Well valley pans can leak and fill the middle of the vally and spills over the front or rear, old Audi v6s were known for head gasket oil leakage doing this. And yes Valve covers can do it to. With the miles valve cover is probably the cause.

my 4.2 leaked from the valley gasket and the oil filter housing and flowed the same path, however, the 3.2 may be different in design, could be valve covers but my experience with valve covers has always been very small trace leaks

I think this is the valley pan it makes sense. Should I try to tighten the bolt or replace the entire gasket? I take a look at this post as reference : https://www.audiworld.com/forums/sho....php?t=2764902



The valley pan should be the bottom metal thing where 3 tubes are connected right?(2big 1small)

It doesn't seems too hard to replace am I wrong?

So I did order two valve cover gasket and one crankcase gasket. We'll see if it will fix anything.

I finally remove the intake to see what's going on and I'm really not sure the crankcase gasket is due. You can see on the picture there's oil near the oil filter and breather hose. Anyone know where It could leak from. There's a lot of carbon deposit on the left side below the two hole
