Steam cleaned engine with power washer while engine running. Observed car started sputtering an hour later then almost died coming home from work. Lacking power and acceleration. Next day checked spark plugs and distributor pack. Tried starting vehicle and could not get it to turn over. Did observe minor oil at base of 3 out of the 4 spark plugs.
Still exists at 142,000 miles. Simply replaced plugs/wires twice previously and the car runs great.
(Valve cover gasket and two o-ring seals) Oil in two spark plugs driver's side! Noticeable when car is heading downhill!
