[QUOTE="e34_lover, post: 619887, member: 16259"] Had a feeling my valve cover gasket was leaking Removed my spark plugs Found oil on the threads but I am not really sure if its there from a previous repair or if its a new problem. Tips are carbon fouled because the car has been running rich. Culprit would be the header flex joint leaking, header to cylinder head leaking as well as the O2 sensors being old. These leaks cause the O2 sensors to adjust the air fuel mixture because of the excess oxygen. Probably why I am down on power!
