Can a small block chevy engine use too much oil?

Can a small block chevy engine use too much oil?

It’s worth checking if your engine uses oil. While small block Chevy was the engine in our case, we’ve seen this same problem with small block Fords as well. This will be true with any engine that has a common area between the lifter valley and the intake ports.

What can happen to an oil filter when the pressure relief?

Its purpose is to open when engine oil pressure reaches a certain value. A problem with the pressure relief valve can cause damage to the engine oil filter and to the engine itself. Modern oil pumps are either driven off the camshaft, crankshaft, or timing belt/chain.

How does the oil filter in a car work?

The pump turns and pulls oil from the pan through a pickup tube. It then pushes pressurized oil through the oil filter and into the engine. There are two common types of pumps: • Gear: A gear-type pump uses two spur gears in a housing. Oil is pulled into the housing and through the gear teeth, where it is pressurized.

What’s causing excessive oil consumption in my engine?

Like your engine, I did not notice any telltale blue smoke on deceleration yet the engine continued to burn oil at a prodigious rate. Eventually, I yanked the intake manifold and discovered small dots of oil on the floor of nearly all the intake ports.

What kind of oil pressure does a big block Chevy have?

This may sound simple, but we’ve seen this happen many times. In a situation that recently occurred at Westech Performance, dyno operator Steve Brule’ witnessed a significant dip in oil pressure above 5,000 rpm on a 600 hp 468ci big-block Chevy.

How to avoid common causes of blow by and oil consumption?

Here are some common causes of blow-by and excessive oil consumption and how you can avoid them on your next engine build. The combustion process is never perfect. Even the best street engine never seals all that combustion pressure. A certain amount of cylinder pressure will always find its way into the oil pan.

Where does the oil come from in a Chevy engine?

This Barnes four-stage pump has three scavenge sections that pull oil from the pan and pump it into the oil tank. The main oil supply line from the bottom of the tank feeds the pressure section at the rear of the pump, which supplies pressurized oil to an adapter bolted between the block and the oil filter.

Why does my street engine pull too much oil?

Either way, this is wasted effort. If your street engine tends to pull too much oil through the PCV valve or the valve cover breathers are constantly wet, check to ensure the valve covers are equipped with vapor separators like these. If the valve covers are not equipped with these separators, the PCV will pull way too much oil into the intake.
