I found that all the spark plugs were fouled with dried oil but no oil in spark plug holes. The spark plug threads have a little oil. The boots are dry and clean. Or did the oil in the wells just dried up? No oil outside the valve cover and I changed the valve cover gasket myself and I did change the gaskets around the spark plug holes. Strange. The spark plugs are pretty fouled up. Any pointers to what may be going on?
