New to the site... I've got a 1988 Suburban, 350, 4x4... and a question about oil pressure. When the engine is cold, the oil pressure is fine. (have mechanical guage) When the engine gets up to temp, the oil pressure drops at idle... at a stop sign, for instance. There are no motor distress noises, and when I start rolling again, the rpm's bring the pressure right back up. I've gotten rid of most of the gremlins that have been plaguing me with this truck, and would like to keep it around for as long as possible. Any advice/input would be greatly appreciated. Thanks! I discovered the cure to the sagging front doors on this site today, so I can finally take care of that tomorrow.
