Question about 1998 Audi A4
Oil is leaking onto exhaust manifold on my 2.8 quattro 1998, the leak is on the left as you look at the engine from the front, I had the valve gaskets replaced but the leak remains, any sugestions would be greatfuly received
It's very possible that the gaskets weren't installed correctly. Unlinke other cars I've owned, my 99 A4's valve cover gaskets are actually somewhat longer than they need to be (about an inch or so), and you have to be very careful when installing them that they don't get pinched outside the "channel" that they're supposed to sit in. I'd be willing to bet that the installer bumped the gasket when replacing the valve cover and knocked it out just enough that it's allowing oil to leak past the gasket. I'd pull the valve covers again and verify that they're seated correctly. I would bet they aren't - there's really nowhere else on the 2.8 for the oil to leak where it could hit the manifold.
