oil in my spark plug hole

ight i went out to change the spark plugs on my car. got through 1 2 and 3 and when i took off the 4th wire there was oil all down in where the spark plug sits and all over the spark plug wire. people have been tellin me that it may just be a valve seal or the gasket. there is no blue smoke coming out of the exhaust there is just oil in the spark plug hole. and just to make things worse on that day i checked my oil and the dipstick registered that there was no oil. had to add 3 quarts. pleez help me and tell me what u think. '91 eagle talon tsi fwd.

Change the VC gasket and the plug well gaskets and torque to spec.

This should be in problem diagnosis.

i had the same problem on my 99 gs.replace the valve cover and spark plug gaskets.one large rubber one goes around the outside and small round ones under each plug.
