I've driven my Riv somewhat infrequently and decided to take it out last weekend. It worried me greatly when, what appeared to be oil shot out of the tailpipes. I immediately decided to pull the plugs and do a compression test. I let the engine warm up and, pulled the oil cap to see if there was anything spitting out of there, nothing that I could see was blowing out. Pulling the plugs they were all darkened somewhat, but to me they don't look that bad. I'm not sure when they were changed last, but I will obviously be putting in new plugs now. A compression test showed: #1 175.5 #2 176.5 #3 165.5 #4 168.5 #5 169 #6 173.5 #7 173 #8 175.5 To me this looked really good. The engine is modified slightly and has always run like a champ. Now when starting it up for the warm up there appeared to be condensation in the pipes. The pipes also have black powder on the insides...so I'm wondering the car just isn't running way to rich perhaps? Is there anything I should look at to be safe? I DO not want to drive the car if I could be stressing something out within the engine. The car sounds fine, purrs for the most part. Thank you.
