If the tapping noise speeds up with the speed of the engine, it's a worn valve lifter.
If the service light is on, change oil and filter, if tapping is still there, the lifter is the culprit.

Valve tap cause


Most engines now use hydraulic lifters and they can leak a little, this causes space between then lifter and the push rod. This results in a tapping noise that goes away when they get warm or fill back up.

2002 grand cherokee engine tapping loudly


My first guess would be a failing valve lifter. They can become weak with age and not able to hold oil pressure.
Especially in an engine with that many miles on the clock.
If the noise is constant you may be able to find out which cylinder by running a compression test. maybe.

2002 grand cherokee, overland 4,7L engine doesnt


Hi Joko,

What you are describing is a failure of a main circuit. The first thing you should check is yo make sure that your battery is in good condition and that the cables are clean and tight. Let me know if yu find anything wrong there. Then there may be another main circuit problem. Check all of the fuses in your fuse block in the engine compartment. If any of these fuses are blown, it will usually cause several things to not work. If you find any fuses blown, DON'T REPLACE IT YET. Let me know WHICH fuse is blown and I can help you find out why it blew so you can get the problem fixed.

Get back to me on this and we will continue.

Tapping noise on start up then fades away all together within 30-40 seconds, could this be wrong verosity oil or? 2004 workmate 2.7 petrol hilux


The tapping is normal at start up, and is caused by lack of oil at the top of engine. The sound goes away within the time frame you stated (30-40 seconds). You have nothing to worry about.

Ticking/Tapping when car starts but goes away???


I had what sounds like the exact same problem. It was an exhaust leak from the left (driver's) side exhaust manifold. This engine has a history of the manifold bolts breaking and causing the exhaust leak. The engine is also used on some Dodge vehicles. It sounds like a tick and I almost mistook it for a bad lifter. I took it to the local Jeep dealer who confirmed the exhaust leak. I replaced the left manifold completely and replaced bolts/gaskets on both sides (left/right) and it fixed the problem. Be careful, as the dealer tried to gouge me on the price. You are looking in the ball park of $600 parts/labor. I got parts for $120 and it took the better part of a work day to do the job.

2004 gmc envoy engine tapping sound, it has plenty of water/antifreeze, and plenty of oil.


We have the same tapping sound on our 2003 Envoy six cylinder engine. I believe the sound is coming from the radiator fan clutch assembly. When the engine reaches its operating temperature and the fan clutch engages, the tapping sound goes away.

I have a 1998 Jeep Grand Cherokee 5.9L, and recently, the vehicle has developed a tapping sound in the front passenger dash near the A/C vent. It began as just an ocassional tapping, and then became more...


Check engine oil level and confirm engine lubrication. Could be the tappets clicking due to not enough oil up there. Does noise go down as engine heats up?
