Having problems with your 1996 Toyota Avalon ?
Oil is leaking into the spark plug tube of my 1996 toyota avalon xls
You could try to tighten the plug or plugs .You see some plugs have a gasket and some seal to the engine block where they thread in to the cylinder block. The olny thing that could cause is the plug being lose or if they have been removed a lot of times and there is a gasket at the base of the plug that has been over compressed or the worst thing that the threads in the cylinder are striped in witch case you can get what is called a helicoil to repair the thread in the cylinder block. But i would try tightening the plug that is leaking this is the most likely thing that could be happening
Had the same thing happen to a '94 grand am that i owned. If the car still runs and it's not leaking that much, just leave it. That's what I did. Didn't to any further damage. It'll be expensive to fix. Can't remember how much.
