im fixing a sled for a guy i work with. He told me that it wasnt running and he thinks it was getting to much oil. So i try to do a compression test, had both plugs out. Go to pull the motor over and oil comes shooting out the spark plug holes. I pulled the heads off of it and it had about a half an inch of injector oil in the cylinders..... anybody know why there would be all that oil in there, and how it woulda got in there?? Im thinking the crank is full of oil as well and ill have to pull the jugs off.
