Can low oil pressure cause noisy lifters?
But unusually low oil pressure in an engine, regardless of mileage, is often an indication that something is seriously wrong and requires immediate repairs. That “tappet” noise may be only one sticking lifter but it may also indicate an oil flow problem that will eventually cause damage to at least one valve.
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.
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. This condition may also be noted by a lower oil pressure reading on vehicle oil pressure gauges or warning lights may come on at low idle conditions. It’s been reported these engines may start to lose oil pressure after many engine temperature cycles.
What should I do if my valve lifter is making noise?
Flush out the old oil. Unscrew the cap under the car and place a container or bowl under the cap. Rinse your valve lifter with an engine flushing agent like Liqui Moly Engine Flush after the leaking of oil has stopped. Pour the new oil according to your engine specifications. This is probably the best solution to avoid noise from lifters.
Why does my lifter make a ticking noise?
If the suitable oil for the appropriate engine is not provided, then the oil will end up being too heavy or too light for the engine. This kind of improper lubrication will result in the buildup of dirt and sludge which will prevent the proper functioning of the engine by making metals come in contact to cause the tapping and ticking noise.
