Ok its a 90 gtu with about 100k on rebuild(think mazda reman), I keep finding oil on the ouside of the plugs(white part) Looks like oil from the fill tube, but it is very black, way darker than colour on the dipstick. Today it looked like it was going down the threads of the plug. The motor pulls hard and smokes a little on start up and on decel, if pushed above 6k. Burns about 1 quart every 1k, so nothing out of the ordinary on that note. So do I need to worry about a side seal or corner seal about to go? Thanks!
