Its not a big deal to have the valves adjusted on this vehicle. But before you do that have oil pump pressure checked.

When car is on whether driving or idling, it makes tappping noise.


Could be lifter noise...valve cams, parts of the engine, are supposed to move the valves up and down to let in air and let out exhaust...there are lifters that good between the cams and the valves to make sure the valves are tight against the cams, they maintain the tightness even when things wear...when the lifter stops doing its job, it lets a gap form between the valve and the cam, and a tapping is heard, actually metal hitting against metal...this could be from the lifter being damaged, dirty, or starved for oil...make sure your oil level is right, make sure the oil is clean...sometimes a dirty lifter can benefit from a fresh oil change...if the tapping keeps up, damage can occur to the valve ends or cam shaft...you probably wouldn't notice the engine not running as well, unless damage occurred that caused to valve to stop working...there are lots of other sounds from the engine that are bad, like persistent knocking, which is a piston in the act of breaking, and not so bad like ignition knocking from using too low an octane gas...depending on the engine type, tapping could be lived with for years, and sometimes lifter replacement, if needed, can be fairly inexpensive...good luck...

Hello, This is the problem i am having. my 2001 chrysler sebring ran low on oil for some unknown reason and the oil light was coming on. Shortly after the engine started to have a knocking sound to it....


i think your engine may be junk now. its a good idea to check oil on any vehicle daily as suggested in any vehicle owner manual. the piston rings could be worn out causing it to use oil or a bad head gasket, or maybe u have a oil leak you dont know about. wish you luck, id probably get a new car or replace the engine since more than likely the crank shaft bearings are junk causing a rod knock

96 Eclipse 2.0 non-turbo Engine has a tapping sound that sounds like its coming from the top of the engine. The sound is loud enough to make it difficult to tell where its coming from. I took the valve...


Most likely cause is a hydralic tappet. Mits are well know for top end noise. Note we are talking about a tapping or clicking sound not a knock. You can try using an engine flush product if the noise is getting bad and then changing your oil. Generally if the oil is not changed regularily eventually the tapping noise gets happens.
