I have a 97 chevy 3/4 ton with a 5.7 vortec v8. It has just short of 170,000 miles. When I am stopped at a light idling the oil pressure drops almost zero. The pressure has always been below the 40 midpoint. The engine doesn't chugg or idle rough and I can't smell anything unusual. The pressure comes back when underway but stays lower than normal. What is the cause and cure for this problem?
have the same problem?
