1989 toyota supra turbo ---Oil in spark plug galley

There are 2 possible options as to where you are leaking oil.

1. Valve (Cam) Cover Gaskets
These are contoured rubber perimeter gaskets that fit into the channels in the Cam Covers. The bolts for the Cam Covers do not need to be very tight.

2. No 3. Cylinder Head Cover
This is the metal thing that is probably cracking and breaking that your spark plug wires seat on. There are several very large female hex bolts in this cover. These bolts are typically where the oil leaks from.

On my car, a friend of mine used "Permatex Indian Head Gasket Shellac" ( Part Number 20539 ) on the bolts as well as replacing my No.3 Cylinder Head Cover ( $45 from Toyota 2008 ) and I never had another problem with oil in the Spark Plug Galley

Indian Head Gasket Shellac comes in a small brown bottle and most parts stores have it in their Permatex section.
