Tapping sound in engine

I have a 1999 1/2 ton Suburban. The last couple of days when it starts cold it taps like it is low on oil after 5-10 minutes or a couple of miles it stops.

I think it might be the tappets/hydraulic lifters.

Sounds like a lifter is failing.

Slight tapping noise from engine when accelerating when engine is warm.Started about 3 days ago but hasnt got any worse.Doesnt do it when cold.


tap usually associated with lifters when vehicle warms up oil thins out and a bad or worn lifter will make a tapping noise --other oil level low --oil needs changing --low level will starve rockers/push rods/and lifters which will also cause tap ---damaged /dirty{sludge oil can cause same problems

Low oil pressure and tapping noise on start up it goes up but after running a bite it drop down to nothing


If the oil pressure does this as the engine worms up and not when its cold then you need to replace ur inserts and maines.--------------------------------------------------------------------------------

1999 suburban lifer noise


if you have a stethascope or even a wood dowel i would check the lifters. if you have higher miles this sounds like a hydraulic lifter pumping up. if you change to a heavier oil it will go away or reduce. thats the cheap fix.

Tapping in bottom for a few seconds then stops motor run good tapping stop i had my oil change also went back and change it again


these engines have hydraulic lifters that open the valves,when you start the engine it doesnt have oil in the top and will tapp for a few seconds it is totaly normal for an older car, make sure you use a napa gold oil filter they filter the best and have an anti siphon valve inside that keeps oil in the top of your engine for cold starts also try some marvel mystery oil its the best, will clean and quiet

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.

Motor started tapping loudly as if there was no oil, oil level was fine, changed oil sound quieted after 20 minutes, sound came back a couple of days later, went away the last couple of days on short...


hi this could be due to your hydraulic tappets, these will start to rattle if the oil has been low at some stage and the oil was to thin this normally sounds worse in the mornings on first start and gets quieter as the day goes on or disappears altogether, what you could do, is use an engine flush, put it in the engine and run it for a period of time, then empty the oil and refill with a thicker grade oil and see how that goes..hope this helps

Oil levels & delayed take offs


its sounds like an altanator problem for the gauges and starting. the tapping is is down to the tappets or the wrong oil in the engine.
