I bought a big gasket set for an engine rebuild on eBay however, I am trying to figure out which oil o-ring is meant for what. I really need to replace the rocker arm shaft cap bolt which is four bolts I think and I looked at the orings on my engine are green but it could be a mistake from the previous owner? I also have no idea where all the other orings and the weird green things go. Is anyone able to help me?
