How does oil filter bypass valve work?

How does oil filter bypass valve work?

The bypass valve – otherwise known as a pressure relief valve – is an integral part of the oil filter. The valve is designed to open when the oil filter becomes clogged or when the oil is too thick. This allows the oil to bypass the filter through a center tube. When this happens, the engine looses all oil pressure.

What is the purpose of the oil filter bypass valve?

If the pressure differential is too high, a valve will open, allowing the oil to bypass the filter. All engine oil filters or heads are equipped with a bypass valve. This valve is needed so the engine does not become starved of oil as the filter clogs with debris.

Which way do oil filters flow?

With typical canister-type filters, it is standard for oil to flow from the outside in. This means that the oil travels through the cylindrical filter media from the outward-facing surface into the inner core.

What is the likely outcome of an oil filter become blocked?

Severe damage to the oil filter is the result when the pressure relief valve is closed. A severe oil leak and loss of lubrication to the engine can be caused by the extreme pressure that causes the gasket to fail.

What does remote oil filter mean?

A remote filter is a smart solution, making work on your oil system much easier and quicker. It can help out your mechanic, who will appreciate not having to take things apart to get to your oil filter and then put them back together afterwards, making oil and filter changes much quicker.

What is an oil filter remote mount?

Remote oil filter bases are mounted to the firewall, fenderwell, frame, or any sturdy, out of the way location, allowing for easier oil changes. The filter size referenced in this section refers to the filter that remote base uses, NOT the filter size of the engine.

What happens when an oil filter gets clogged?

If your oil filter is clogged, the exhaust coming out of your car could be black or dirty. When this happens, you will smell the oil burning as it passes into the exhaust pipe. These odors are a clear sign that you must bring the car into a local shop for assistance as soon as possible.

Do all oil filters have check valves?

And here is the big thing. Most filters these days have check valves in them, and the primary one is an anti-drain back valve. That anti-drain back valve prevents the oil from being syphoned out of the filter when the engine is shut off.

What kind of oil filter do I need for my Pontiac V-8?

The PF24 oil filter from AC Delco is a stock replacement specifically designed for the Pontiac V-8. It’s a high-quality unit that offers excellent filtration and can generally withstand high oil pressure levels. It can be ordered through most local auto parts stores if it’s not already on the shelf.

How does the oil pump work in a Pontiac V-8?

Once the preset amount of pressure is reached, the bypass valve’s check ball is forced off its seat, redirecting excess output flow back toward the inlet side of the pump. Pontiac used three distinct oil pumps in its V-8 engines, and they are often referred to by approximate maximum pressure ratings of 40, 60, and 80 pounds per square inch (psi).

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 kind of oil do you put in a Pontiac engine?

While modern 10W-30 oil can provide sufficient lubrication, heavier oil is often the choice of many professional Pontiac engine builders. That’s because the bearing clearances in most modern Pontiac builds are a bit looser than what Pontiac originally specified for production engines.
