Question about 1990 Toyota Corolla
1990 Toyota Corolla, I took a spark plug wire off and oil jumped out the hole. Why?
If Biggy1 has described it right, I think when you remove the WIRE to the spark plug ( not the plug itself ) and oil jumps out, there is a cylindrical seal that needs replacing and one does not need to even remove the cylinder head.
I have the same problem with my corolla. On the other hand if Biggy meant when removing the SPARK PLUG oil was on the contacts....

An oil fouled spark plug indicates an engine with
worn piston rings and/or bad valve seals, allowing excessive oil to
enter the chamber..you need to change the piston rings....
