I have a 2004 Suburban 5.3 which has an oil leak that drips on the exhaust header, but cannot see where it is coming from.
Changed valve cover gasket, then had to helicoil all four threaded openings for the valve cover bolts. Oil still leaks. I have a gut feeling it is a cracked head. Can a bad head gasket leak oil on the outer edge of the head and drip on the exhaust manifold?
Pretty bad leak too. When I stop at a red light smoke pours out the divers side of the hood.
