I have a moderate oil leak on my drivers side valvecover. I bought the gasket set at Advanced Ato, but when I went to take the covers off, I couldn''t get clearance for the brake booster. IS this typical? There is maybe 2 inches of room, and I have to have atleast 4 inches to clear everything. I am really hoping that I don''t have to yank that booster, or hand it over to a mechanic.
