Message I have a really bad boost leak in the back of my engine, near the middle of the plenum. While doing a boost leak test I sprayed some soapy water back there and the leak seems to be coming from the intake valve cover gasket! Is this even possible? The only way I can think of is if I have really bad valve seals. Has anyone ever seen this before?
