I pulled #2 and #3 spark plugs out of my h23 prelude today and was rather suprised to see oil on them. I am not seeing a lot of smoke from the engine, or the exhaust and im not loosing oil from when i change it. I'm 2500 miles away from hitting the 200,000 mile mark and am concerned if my engine is going to make it. Basically i want to know if its worth trying to save this engine by replacing possibly damaged piston rings, when its probably new h22 time. thanx.
