I have oil on all my spark plug threads but no oil on spark plug socket end. Ik the plugs are under and away from the valve covers so idk how oil got on plugs threads unless its can still get it that way if cover gaskets are bad. Idk if the valve seals are bad because I get no smoke out if exhaust or oil on piston head (I used a scope car been sitting for a week) anyone know before in pull the valve covers and replace the valve seals

Also PVC system is ok. All new

Sorry my english isnt...
