Is there a lifter noise in a GM engine?

Lifter Noise And Low Oil Pressure On GM Engines. The AERA Technical Committee offers the following information regarding Lifter Noise And Low Oil Pressure On GM Engines on 1997-2013 GM 4.8L, 5.3L, 5.7L & 6.0L engines. This noise is only noticeable at idle and a slight increase in RPM will diminish the noise.

How can I get rid of the engine lifter noise?

This will continuously pressurize and de-pressurize the lifters, sending the solvent through and breaking lifter plungers loose. Drain the oil into your oil drain pan, but leave the old oil filter in place. Refill the engine with very lightweight engine-flushing oil.

What causes low oil pressure and lifter noise?

The noise is also only present on a engine that has been brought to normal operating temperatures.

It’s been reported these engines may start to lose oil pressure after many engine temperature cycles.

Why does my engine make noise when I Turn on the engine?

Hydraulic lifters allow the valve lift to increase with engine rpm by filling up with oil as the oil pressure rises. The oil inside pushes the rocker arms further away from the camshaft, which causes the valves to open further. Oil pressure failures are usually at the root of lifter tapping, also known as lifter collapse. Check the oil level.
