1993 Audi 100 Question: engine leak
If you replaced the valve cover gaskets, make sure that they are not leaking. You can do this with a mirror. I would also look at the head gaskets as well, on German cars they can leak oil when they get old. Clean the area off with some spray brake cleaner, ( with the engine off and cool ) then start the engine and watch where the oil comes from. - dandd
Problems with air leaks and the fuel injection may cause starting difficulties.
An External oil leak may develop from the valley pan gasket (under the intake manifold) and/or the head gasket.
