Hi to everyone, I'm new to this forum, but I've been consulting it for a while, nice place.
I've got a 92 240sx, about 50k miles on it. When I changed my spark plugs while doing a tune-up, there was oil in the spark plug well (mostly in one of them) and it wasn't at the bottom of the plug (where the tip is), but on the top part of the plug. What do you think it could be? Valve cover gasket is what I think. Anyone encountered this before?
Thanks for helping.
