Finally got to tearing down my 800 Indy motor. Has some miles on it and bought used. I bought it primarily for grass drag racing. Little behind on getting it ready. Working on asphalt sled and several races being cancelled, motivation to work on it has been lacking. Anyhow, tore the motor down and found the pto side full of new oil. I am used to working on Doo triples. They occasionally do this from a failed check valve. Is this the same thing? Are these known to do this? Or should I be looking at something else? Any way of finding out which oil injector might be leaking?
