I have had the car for 5 years now and its been running the same boost since day, i cant believe that the oil pump could be gone as i have recently replaced it and its not really a highly technical thing that can fail once it has been working. Its a genuwine ford pump and it was primed with fresh oil and fitted with new gasket following the correct procedure. I did think maybe it had spun a shell as shane said but who knows. I am going to whip the head off now and see what everything looks like. BIGLEE how can you be so sure its the pump mate you are making feel this sense of hope but i cant be as sure as you. I dont wana change the pump again and descover it was the engine anyway, but everyone who has replyed: i do appreciate it and thanks alot
