Previous history (just in case) :
I bought the motor with HKS 555's on it. They had no O-rings on them flooding the intake manifold, and cylinders, up to the spark plugs. That's fixed now.

Problem : The car will start... with fresh plugs. But, the plugs will get oil on them, and on the start of the threads. I have to use sandpaper / buy new plugs to get it to start again. Cause / Solution?

What I mean when they have oil on them, I mean the electrode, and beginnings of the threads. The oil doesn't come into the actual spark plug well.

Maybe the valve cover gasket is leaking? The inner part with the 4 rings...

I thought about that, but I wasn't sure. I thought if that was leaking it would maybe go into the actual spark plug wells?? Someone correct me here.
