Hey, my guess was closer than DB's! I was lucky! I was ready to mention here that an overheating engine could partially seize as DB said, sometimes without permanent damage. The pistons (made out of aluminum) expand faster than the block, and can "grab". When the engine cools, it may start just fine again! This should not be directly related to oil pressure though. Heat can only affect oil pressure through the loss of viscosity, but this effect cannot be enough to damage the engine. The oil cooler is usually needed for high speed driving when the oil is sheared heavily in the bearings and pistons. At idle, the only temperature loading to the oil is through piston cooling, and based on my experience on my 440s, the oil is fairly cool at idle.
