Great Americans,
I have an oil pressure issue that I am troubleshooting that I'd like to hear your thoughts about. When I crank my engine cold, the oil pressure indicates 10-15 psi. As the engine warms up and stabilizes at 195 degrees (perfect in range) the pressure slowly drops down to zero and stays there. I have new oil and a new oil filter installed and the engine sounds great. Based off of my experience, I'd say that the oil pump is probably working fine, but I have a bad indicator feeding poor data to my gauge. Second most likely issue is a bad gauge. Third most likely issue is a bad oil pump.
The book says 15psi min at idle, and 40-50 psi operating.
What do you guys think of my assessment based off of your experience and what you see in your trucks? One thing that I didn't do (out of consern for possible oil starvation) was to rev the engine and see if the psi increased linearly or not. I think that I might try that and see if I can get it in range if it's still sounding good this weekend.
