What is normal engine oil psi?
between 25-65 PSI
The ideal oil pressure varies depending on the car brand and model, but generally, the ideal oil pressure is between 25-65 PSI.
What is the idle oil pressure?
Typically, at idle you will have 10 to 15 psi, with 30 to 40 psi at driving speeds. A high oil pressure reading on your gauge means: The oil is too viscous (thick).
What is the compression on a 4.3 Vortec?
RE: Cylinder compression (PSI) on 4.3 Vortec? The minimum compression in any one cylinder should not be less than 70% of the highest cylinder. No cylinder should read less than 100 psi (690 kPa).
What kind of oil does a 4.3 take?
The 4.3 liter Vortec V6 engine uses 5W30 engine oil in colder climates and 10W40 in warm climates.
How much compression should a 5.3 have?
If a factory value is not available you can estimate it by multiplying your intake pressure by your engine’s compression ratio – for example a 2005 Silverado with a 5.3L V8 has a compression ratio of 9.9:1 – if you measure an intake pressure of 17 psi you can expect a cylinder pressure in the 170 psi range.
What is the cause of low compression on one cylinder?
There are several causes you can eliminate if your cylinders are losing compression. Exhaust valves and air intake valves at the top of the cylinder can also get overheated, and leak gas or the valve seals can become too worn to seal the gas in properly. Either way, the result is often low compression.
What happens if you have low oil pressure on a Chevy S10?
One of the most serious issues that can happen to your Chevy S10’s engine is if it ends up with low oil pressure. Low oil pressure will cause the engine to One of the most serious issues that can happen to your Chevy S10’s engine is if it ends up with low oil pressure. Low oil pressure will cause the engine to seize up.
What does the oil pressure sensor on a Chevy 4.3L do?
The oil pressure sensor on a Chevrolet 4.3L V6 engine is part of a network of sensors that provides the powertrain control module (PCM) with information about the engine. This sensor measures the pressure of the engine oil and relays this data to the PCM. When the PCM detects low oil pressure it illuminates the oil
Is there a problem with the Chevy Vortec engine?

Owners [&have&] reported the car requiring [&two&] quarts or more of [&oil&] in between normal [&oil&] changes. The excessive [&oil&] [&consumption&] is likely to be caused by the Active Fuel Management system.
Why is my Chevy Vortec 4300 V6 leaking fuel?
In the L35 and LF6 engines, the spider injectors are known to leak at the pressure regulator and at the supply and return lines due to a design fault. Outside of leaking fuel onto the exterior of the engine itself, it can cause excess fuel to get sucked into the engine.
