i have a mild 350 that once hot, has only about 13 pounds of pressure at idle. the psi starts off great when i start it but as it warms, goes down to 13. Upon acceleration, it climbs mormally to about 35-40. Would it be wise to install a moroso oil accumulator to keep the pressure up at idle or would i have to tear into the engine and see what the problem is? i have been running this engine like this for a while now. Do you think anything is severely damaged? I do get oil to the rockers but 13 psi is pretty low!!
