I'm trying to track down a recent oil leak on my '03 3.0 B6. There's no evidence of a leak at the usual spots (plug and filter)...and I just changed the valve cover gaskets, no leak there either. As I was changing the valve cover gaskets, I noticed oil on both of the timing belt covers.

Any ideas on what the source of my leak might be?

 

camshaft seals?

 

^^ Either that or the head gasket itself. More than likely the camshaft seals, someone on their 1.8 had the same problem.

 

Thanks guys. I'll hope for the cam seals over a head gasket.

How's the repair job for the cam seals? Reasonable for a DIY or is this one of those disassemble half the motor for a $6 seal job?
