One more question ? The oil has oddly traveled up into the intake a little:dontknow:
Could it be possible that the new valve seal is leaking? If that was the case I would think the oil would be more strait down the valve and out?
Look at your old gaskets to see if you can see witness marks for any oil seeping/leaking. NEVER clean your old gaskets before checking them. You can learn alot from reading them.
Look at the old gaskets in the area where the oil was leaking and see if you can see where the oil was leaking through the gasket and leaving marks...
