Check to see if your pcv valve actaually works, there should be vacuum at idle. The hoses go soft on these and suck together on the inside. Check to see if your oil pressure switch hasn'tdeveloped a leak, it's by the dist in back. If you can't see the leak take to a car wash and wash the engine to see where it's leaking as well.
