I suddenly got this problem where at cold start the oil pressure is around 40psi. As the engine warms up, the pressure drops. Finally to zero. But the engine(304) still purrs like the day I had the rebuilt unit installed. The engine has ~7k miles on it. Tried two new different brand mechanical pressure gages, same result. Installed a new bosch filter and 10w30 oil as I've always run and noticed the oil smelled heavily like fuel. Installed a new mechanical fuel pump, oil and filter again. No change. I'm thinking the rod/cam bearings were ruined. What do you guys think? Anyone dealt with this scenario? Anything else that would cause this?
