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.

What can cause a knocking at the right hand side valve cover

Hi , usually a knocking / pinging from the valve cover indicates a lifter tapping. Could be worn out or just worn. Do you change your oil every 3000 with high quality oil? (I always have used valvoline standard with outstanding results) Dirty oil and filter and or incorect weight oil and or using synthetic oil in older cars can result in lifters tapping. If your oil is under 2000 miles since last change and you used a high quality oil (watch who changes your oil, some places use inferior oil because its cheaper) you can buy a pint of oil treatment formula to quiet noisy lifters to coat the lifter and quiet it down. It is a sign of engine wear, but one lifter tapping a bit wont really hurt your engine mechanically. If they all get noisy, time for a valve job. Root cause is wear due to insufficient lubrication. The lifters on newer cars are all hydraulic and they self adjust. No manual adjustment is possible. Bottom line: keep your oil changed regularly using a high quality non-synthetic oil for your 1999 vehicle.

Got a 2001 chevrolet cavalier 2.2L with apx 150k miles and began noticing a light tapping noise coming from the head noise speeds up when the kar revs up noise is not real loud and is coming from head not...

I had a 96' Cavalier with a 2.2l, noisy lifters. Kept oil change and wound up doing a head gasket at 303k, I think they are just noisy. I do know that the timing chain tensioner is not a lubricated part and it is just like a nylon type material. You might check to see if the noise is coming from behind the timing cover. I had to replace that tensioner twice over the lifetime.

The engine knocks at higher rpm, only at high rpms

First no matter what check the oil level and then if it's a high rev tapping you need to allow the oil to flow through the engine block to try to coat and settle your valves.

But if it's really " knocking " sounds like your lifters and rocker arms are allowing your piston rods to clatter and that needs to be looked into fast.

My lifters are tapping what can i do to solve this problem? My 2005 magnum did run low in oil does this mean my motor is shot

Not necessarily, but you need to check a bunch of things.

Did it run low on oil or out of oil, did the oil pressure go to zero for more than a minute.
Yes - you may have problems
No - you probably did kill things - but watch your cooling level for a while - using water could mean a head gasket leak

Is it really lifters, listen real close and make sure you think that is what it is.

Lifters tap because they loose their oil pressure. I would run it for a while and see if they come back up. Else you need to identify which one and replace it.

This is not an overwelmingly serious problem unless you are reving high. The lifters can be quite loose and not cause any catasrophic problems.

I good grade of low viscosity synthetic oil might also help.

2.7 99 dodge intrepid skips when warm

solid lifters? i could be wrong but i think they are hydraulic lifters. ive had quite a few of them not pump up when re-installing the valvetrain and cause a tick. pull off the valvetrain and check to see if all the lifters/tappets are firm with no squish. that might be your problem

Knocking when started,noise disappears in higher gears.

try an oil change my brothers isuzu used to do that and he did an oil change resulting in a fix. If it gets worse you could have a piston shoot through the oil pan.
