Valve Train Noise
So, Valve and hydraulic lifter noise has a clicking sound, that usually quiets down as you raise the engine RPM’s.
Timing Chain Noise
Many of the newer engines have overhead camshafts with longer timing chains. The chains ride against a nylon guide (a chain guide) which, in time, begins to wear.
Detonation, Pre-Ignition (Pinging) Noise
You usually hear this noise when accelerating the vehicle. Consequently, Most people call this a pinging or rattling sound.
Connecting Rod Noise
Connecting rod noise is caused by excessive clearance between the crankshaft and the connecting rod bearing surface. This happens when you have low oil pressure causing the bearing to run dry of lubrication; which in turn will damage the bearing and crankshaft surfaces.
Crankshaft Bearing Noise
Crankshaft bearing noise is also caused by low oil pressure; which damages the bearing surfaces and could eventually damage the crankshaft itself. This type of noise is usually described as a rumbling or thumping sound deep in the engine when accelerating.
Piston Slap
Consequently, This noise is caused by excessive clearance between the piston skirt and the cylinder wall. As a result, is usually found on high mileage vehicles.
Piston Pin Noise
Piston pin noise is similar to valve train noise.
Whining Noise
A whining noise when an engine is running; is usually an indication of a bearing that is on the verge of failure. Consequently, This noise will increase as the engine RPMs increase.
