What kind of oil pump does a Pontiac have?
The Pontiac oil pump is relatively simple. Its cast body houses two spur gears that draw in, pressurize, and disperse oil throughout the engine. A ball-type pressure-relief valve regulates oil pressure to 40-, 60-, or 80-psi depending on the unit and engine build conditions.
What kind of oiling system does a Pontiac V-8 use?
In addition to 60- and 80-psi pumps in its basic line, Melling offers those same pressure ratings in its Melling Select line; a higher end line that’s assembled to tighter tolerances, and can require less preparation for high-performance applications.
Which is the best race oil for a Pontiac?
Many professional engine builders consider Penn Grade race oil from Brad Penn among the very best available today for highperformance use. It’s a partial synthetic that contains high levels of desirable additives and offers excellent protection at all performance levels. It’s ideal if your Pontiac is equipped with a fl at-tappet cam.
What kind of oil to use on a roller camshaft Pontiac?
Modern-spec synthetic oil is suitable if you’re running a roller camshaft in your Pontiac. Other oils marketed as “race” oil and/or are recommended for “off-road use only” generally have increased levels of all desirable additives and are an excellent choice regardless of camshaft type.

What causes low oil pressure in Pontiac V-8?
The basic design works sufficiently for the intended applications, but its main weakness is its ball-type bypass valve. Should debris get caught between the check ball and seat, excessively low oil at idle pressure can result. Melling produces several different oil pumps for the Pontiac V-8.
What does an oil filter do on a Pontiac V-8?
An oil filter is designed to remove and collect small particles and debris that’s suspended in oil as it circulates throughout the engine. AC provided Pontiac with its oil filters for its V-8s. It’s a high-quality design that’s rather large and offered excellent filtration and flow.

What kind of oil do you put in a Pontiac V-8?
Diesel oil is a suitable oil that offers plenty of protection for a typical high-performance Pontiac V-8 operating up to 6,000 rpm, regardless of camshaft choice. I feel the best oils available for any Pontiac V-8 are produced by Brad Penn and Joe Gibbs.

What is the oil pressure on a Pontiac 400?
External oil pressure gauge says 60+ lbs on startup. 35+ warm idle 40+ at highway speed and 15+ at HOT idle. Checked on rear of motor at oil pressure sending unit. Removed the timing cover and checked the timing dots are lined up. They are.
Why is there no oil in the rocker system?
The rocker system is not oiling. What causes this and how can I fix it? Do you have an oil pressure gauge on the dash? Yes we hooked 1 up 50 pound of pressure idling. 50 PSI at idle is quite high on this motor hot. Are you hearing top engine ticking? Have you verified no oil at rockers when running with V/cover off? Did this start all of a sudden?
