I recently bought a 94 2 owner vette. THis car appears to have been babied all throughout its 69k miles. everything on the car works perfectly, my concern is when idling, or rolling up to a stop sign the oil pressure reads just above the hash mark. when driving normally it reads around 20 lbs, and when throttling it, it gets up around 40-55. My concern is the idling oil pressure, is this a concern or is this standard for an LT1 engine?
