You didn't find oil in the pistons, you found oil in the spark plug tubes. This is fairly common on older engines. Over time the seals in the valve cover begin to leak around the spark plug tubes. Oil then works it's way into the tube and settles in the bottom.
There is an easy fix. Simply replace the valve cover gasket.
Yeah, kind of. The valve cover gasket needs replaced. The seals around the plugs go first because of heat. If the oil mark was near the top of the plug boot, replace the valve cover gaskets/seal. If it was near the bottom, slap in the plugs and wires.
The fault is due to the valve cover gasket passing oil into the spark plug wells. There are circular seals under the valve cover around each spark plug well opening. These spark plug well seals come with the valve cover gasket set.
Yes the oil can cause the car to lose spark, the oil leak could be caused by the valve cover gaskets around the spark openings, but 9 times out of 10 it is the spark plug tube "O" rings. The top of the valve train comes off of the head, the "O" rings are between the two halves, that will fix the oil leak.
If oil was just around the plugs you have a oil leak somewhere . If the tip of the plug that goes in the motor is covered with oil it is either worn valve seals or piston rings. If it leaking oil look at the valve covers this is on of the most likely place for oil leaks.
not really the valve cover needs replaced get a valve cover gasket kit it will come with the gaskets that cover the spark plugs .if you let it go after a while it will contaminate or spark plugs wires and cause a misfire or your car will start missing.please rate this answer thanks.
i also have the same problem regarding the oil leak. this is due to the spark plug gasket leaking and you will need to replace them. they are circular gaskets about 1.5 inches across that fit to the underside of the rocker covers and prevent oil from seeping down the long spark plug hole. when i investigated my leak i assumed it was just the rocker cover gasket that was leaking but once everything was removed it is obvious.
