What kind of oil pump does a Pontiac use?
A note from Rocky: The Butler Performance Pro-Series oil pump is an excellent unit that we use in our own Pontiac engines. I highly recommend them for the reasons outlined in the story below. If you’re interested in purchasing one for your build, Butler offers 2 versions: A 60 lb pump and an 80 lb pump.
What causes oil pressure to fluctuate in Pontiac?
If there is a weakness within the Pontiac oil pump, Butler believes it’s the ball-type bypass valve. “If some debris or a small metal sliver gets lodged between the check ball and its seat, the ball may stick open. That can cause oil pressure to fluctuate, also routing some oil flow back toward the inlet side of the pump.
What should the pressure be on a Pontiac V-8?
When dealing with a typical Pontiac V-8 and production-bearing clearances, pressure at the gauge is usually 60 and 80 psi, respectively. Melling’s Select Performance oil pumps were first introduced in the early ’90s and incorporate improvements to the pump design, displacement, tolerances, materials, and coatings.
What causes the pressurization of the oil pump?
Pressurization occurs when discharge flow meets the resistance associated with forcing oil throughout the engine. Oil-flow volume increases along with engine speed, and a sprung ball-type bypass valve regulates maximum pressure.
