Well, now I'm beginning to think that maybe I too have a oil pump or related problem,besides the timing issue. How can I diagnose the problem of having air in the oil. Before pulling the pump I would want to have pretty good evidence of a problem. Also knowing what or at least one of the problems is would allow for a better remedy, rather than changing out the pump and still have oiling related issues.I have run the engine at different engine speeds up to normal temprature, shut it down and checked the oil inside the filter housing and I did not detect any air bubbles or see anything out of the ordinary. Does the get entrapped in the oil or is there air that is trapped in the heads that can detected by breaking one of the lines at the filter or at the 1/8" openings in both heads.
