With the tensioner , what is the proper way to set? When you take the cap off and remove the spring inside, does the inner part not just screw in all the way to a stop on the threads. The spring doing the automatic tensioning to the chain? I have had another possible cause given to me of sludge build up blocking oil flow or oil pump losing prime causing lack of lubrication and cam breakage! either way I was told that I now have a boat anchor!! This is not been a good day!
