Hello----My oil pressure gage was running almost zero at idle in my 57 Hawk. It has a champion 185 engine. I unscrewed the Studebaker gage from the block & attached a good Stewart Warner gage directly to the engine. It pumped about 75 lbs or so cold, but at full temperature it reads about 10 pounds at a slow idle. When I rev the engine up to highway speed ( I'm guessing about 2800 rpm or so), the gage reads 30 to 32 lbs. I'm doing a compression test tonight.
Question: Are the oil pressure readings above typical for this engine? The 10 pounds worries me a bit. Note: I've only had the car about a month or so. I put Valvoline 10w 40 oil in it. Do I need heavier oil? Thanks in advance---Dan
