Noisey lifter on a 2000 Yukon Denali

When the engine is started it has a loud knocking noise that stops once the engine is warmed up--- I am assuming it is a lifter or crank issue?

SOURCE: '04 GMC Yukon Denali Check Engine Light

Did u put in fuel shortly before the light came on? I own 2 service centers & the most common situation with "Check Engine" lights are because the fuel cap wasn't re-installed or not tightened. When you refuel make sure it "clicks" when putting back on. We don't charge for a "Code Reading" but a dealer will, don't go there. Go, like the others suggested. If it is the fuel cap & you re-install it correctly, the light will go off after a short drive. Good Luck. PS-Don't panic when the "Check Engine" light comes on unless it blinks, if that happens don't drive. PSS-RE: Murray's, Auto-Zone.......If it's a "Code" (the reader will give a #) the code book will tell you the problem. PSSS-Some1 please have Troy W's Mommy & Daddy take away his keyboard. Just because you can put together a "Lego" car doesn't make you a master mechanic. You only repeated what we said except you have a "Napoleon" complex against any1 plugging something in to a vehicle. It's the same as plugging in a light @ home. In conjunction with "kinder" nine out of ten time in my experience it usually is the oxygen sensor(s) which would be about right with the year model

SOURCE: 02 yukon denali security light stays on will not

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.

Hearing noise from my engine of a 2001 Jeep Grand Cherokee Laredo


well either your lucky and you have an exhaust leak (very common on the 4.0 jeep engines) or you have a collapsed lifter, bad wristpin,spun bearing...and other assorted bad mojo.. if it is a 4.0 its very common for them to have exhaust leaks due to the long cast iron manifold. its also common for them to have noisey lifters once they get up there in millage. i have a 2000 jeep and the lifters on it have been making noise for about 40 thousand miles and i havnt had any issues with it. just went to a slightly thicker grade of oil. hope this helps

2000 jeep grand cherokee has a loud knock in engine. Started out as a ticking sound like a lifter, know it is a loud knock. This is a V-8 Engine


If the noise still sounds like it's on top, I'd remove the valve covers and check the rocker arms to make sure they aren't broken or worn. Also crank the engine over and observe how far each travels. If any are different, a lifter or lifter and cam have gone bad.
If your oil pressure is low or the noise is deep inside the engine, likely you have a crank bearing problem. In most cases it's more economical to get a scrapyard replacement rather than do a rebuild.
Before doing anything like that, have an experienced tech listen to it. Only other thing that can make a noise like that is a broken flywheel. A good tech can tell the difference between noises and give you better advice than I can because he can hear it.

MY 2000 Montero Sport has a loud knocking when i Start it UP ESPECIALLY WHEN ITS COLD IT GOES AWAY AFTER IT WARMS UP


Sounds like a hydralic lifter issue. These lifters operate the cylinder valves and run off oil pressure. When the engine is cold and the oil is thick worn lifters tend to rattle. When the engine warms up, everything expands and the lifters stop rattling. There is no easy cure for this except replacing the lifters. Sorry....

noise is caused by lack of oil to lifters, or worn timeing chain. if noise is from lifters it should go away wit proper oil level, if still there needs timeing chain.

Knocking until car warms up


Sounds like a lifter noise. worn lifters can't keep oil in them anymore so over night the oil leaks out. when you start the vehicle, you will hear a ticking noise or knocking noise till the lifters fill with oil again. only remedy is to replace the lifters.
you could try an additive but it's temporary.
