1990 Chevrolet 3500 Pickup Question: engine knock
maybe try a thicker oil with some STP oil treatment - Valleyautotech
Engine is making a knocking sound, and oil pressure light comes on and oil pressure drops.
it does this when the engine is warm. after a few minute it cranks right up.this happens repeatedly
Where is knock sensor
Are thare any anti-knock sensors on a 454 chevy engine?
