Evan F 0 Posted March 1 Have been working on my 92 SLC over the winter and decided to pull the plugs and take a peak with a bore camera and all but one cylinder looks fine. https://imgur.com/a/hlhVfa3 Wanted opinions on if it looks bad and possible solutions. Thanks in advance. Quote Share this post Link to post Share on other sites
oneohtwo 8 Posted Monday at 01:38 PM Not really sure what's going on with the piston - it's bit hard to see from the photo. Could just be carbon deposits? The spark plug looks normal to my mind though. In terms of possible head gasket leak, other things to check or look out for: - water in the oil (white sludge or "mayo") - oil in the water - exhaust gas in water - blue or white smoke in exhaust (blue for oil in the cylinder, white for coolant) - loss of oil/water with no other obvious leak If water was getting into the cylinder you might expect to see the piston look clean where the water vapour steam cleans the piston, so possibly not that. If it was oil I'd have thought the plug would be fouled up, and that doesn't seem to be the case. But as above have a look for the other signs. Which cylinder looked bad? The VR tends to have issues on cylinder 1 and 6, although that's the 2.9l, as far as I am aware the 2.8 you'll have in the SLC is a bit more robust.
