I recently replaced my spark plugs and noticed oil on both sides of the engine where the middle spark plugs are located. Is this a relatively easy fix or am I going to have to wait for warmer weather? Any thoughts would be great. I'm guessing the intake has to come off at the least.
Leaky spark plug tubes, requires removal of the valve covers, upper plenum, and upper engine harness, which can be pushed to the side, then remove and reseal the tubes at the bottom (slight coat of RTV will do the trick), and replace the valve cover and upper spark plug tube gaskets.
Only reseal the tubes that are leaking. This is one of the few instances where you dont want to do them all, "while your there".
