Having problems with your 1999 Chevrolet Suburban ?
Oil Pressure Drops
\015 We were recently driving and when we apply the brake the oil pressure drops. When we completely stop the oil pressure goes all the way down and the Check Gauges light will come on. When we start driving again it goes back to normal. There are no codes being present and we already replaced the oil sensor and our mechanic can't figure out why it is happening.\015
Did the mechanic drive the truck with a mechanical gauge to check the pressure ? The engine bearings or oil pump could be worn enough to allow pressure to drop at idle after it warms up.
