Just when I thought the end was near... Last night, the Haneline oil pressure gauge that normally reads 20psi of oil stopped registering any pressure. I figured since I installed the sender a couple of days ago maybe it was the sender that was bad, esp since I didn't hear anything funny from the engine, so I did about an hour worth of test drive last night. Today, I was going to do the oil cooler + remote filter location kit install. However, when I took the oil filter off, it was nearly empty. Alarmed, I took off one of the valve covers and started the engine to find that there's no oil going to that area, so I guess the guage was right after all. First, if engine runs without oil, shoudn't it be seized up? It's a tired old motor so I wouldn't be very heartbroken if it did but it seems to be running OK. Second, where should I start looking to find the oil pressure problem?
