Default Oil in spark plug hole, 91 2.2???

This is the original 2.2 motor where the plugs are at a severe angle and do not go thru the valve/rocker arm cover. So there's no seal there. There appears to be no oil anywhere else but enough accumulated in 2 weeks to short out the plug and cause it to miss. Where is it coming from? TIA.

Saw your post on the USMB. It has to be coming from the valve cover gasket. I don't know where else it could come from...

But the valve cover gasket is lower than the spark plug hole! And there's no sign of leakage on the top or sides of the cover. I'm totally perplexed.

Which side is it leaking on? If it's the Drivers side, Usually the o ring on the Oil Filler tube causes that. If it's on the passenger side, the only thing I could think it would be is the Power Steering Pump.

how does oil cause a miss ? The outside of the plug is shorted to the head, by way of being screwed into it. Also is the compression healthy in that cylinder ?

You can get a miss because the oil fouls the plug between the center electrode and the grounded prong.

I forgot to add that it could be coming from the PCV hoses on either valve cover. I have had to put hose clamps on them before because the wire type spring clamp could not seal well enough. Just another idea.

This plug boot is not real tight and if I hose down the engine, water will get in there and cause the same problem. I usually sop the water out (but if you don't it will eventually evaporate or boil out, the oil won't).
