Why is my truck ticking while idling?

The tick in your engine could be normal based on the design of your engine or could just be from normal wear from your engine running. As high-pressure exhaust escapes from a crack in the manifold or a leak in the gasket it will sound like ticking or clicking especially at idle or low engine RPMs.

Why does my engine tap when I start up?

Upon start up, the lifter will take a few moments to “pump up” and expand as the oil pressure builds in the engine. During this time, the valves may tap since there is clearance between the rocker arm and lifter. Replacement of the valve lifters usually requires major disassembly of the engine.

Why does my car idle higher at start up?

So if there is a problem it isn’t that car idles higher at start up – its supposed to. Its that it is idling a little high to begin with, both at start up and after warming up. A small vacuum leak can cause that as can a sticking or malfunctioning idle air control valve.

Why does my Chevy Silverado make a tapping noise?

The engine has a deep knocking noise in the lower part and a tapping noise in the upper part . The engine has a miss at idle and no matter how much diagnostic equipment you hook up to the truck you can’t find the reason, but after checking I have found that all the 99 and 2000 silerado’s with the 5. 3 have had a strange miss/vibration.
