i understand what you are saying matey but i just rushed in and openened her up, maybe i should have DONE THE COMPRESSION TEST. To be totally honest i know there is no cracked block, the coolant is perfect and the oil is still clean because it was changed. There is not a single oil leak as every seal has been changed on the engine. I am also sure its not the oil pump and this is purely coz i dont want to believe it having changed it just recently for a genuwine ford one. I have heard from various people that the genuwine ford pump is far better then any high pressure pumps, alot of tuners will say standard ford one all day long. To be honest i am going to take the sump off today and this will confirm everything as i believe the shells are gone.
