Did this video help you?

Jay Mitchell: When, oh when will people learn...Mopar or no car. (or truck) Buy a Dodge Ram. Problem solved!!!!!

Matthew Garcia: Almost all of these motors 2000to06 develop this knock.purchased my 2002 Chevy brand new 4.8 engine started knocking after 17k,now has197k miles and still runs strong.run nothing but synthetic mobile one.

Jay Mitchell: LOL, no, you're the idiot, you with the POS GM junk with engine noise. My Hemi Ram runs like a champ. Great sentence structure too I might ad.

hbnerfful: good oil pressure

Chase Anderson: Every 6.0 I've heard makes that noise. Mine does it but it also has a tick in the engine. Anyone know what that may be? It's not a constant tick, just sporadic 

TheBlackShadow270: Mine does the same. Many people say that's just what they do

CHEAVYguy650: Thank Me Later @ronal1330 Hey It's Your Flex Plate aka Flywheel. Take the transfer case off and wiggle the flex plate. I May Be Right Because Its the Same Problem on my 2000 yukon xl 2500 6.0L. When you started your truck the starter sounded the same bad. Your truck will still run mines been making the noise for over a year I just haven't had the time to find the NUISANCE. LoL Brands Are Brands Every Company Has Mistakes Ford And Chevy Are Both Great! Yet I Still Own Only Chevy.

1330ronal: this truck still running like new i m gona made another video l show u how this chevy engine can live for long time

Niko Petrone: sounds fine.... normal noise

biw1428: Sounds like normal GM piston slap to me. I've got a Silverado and a Caddy Northstar, both of them do it on a cold start. It's due to the fact that the engines are built with a little play between the piston and the cylinder. Once the engine heats up, and the metal expands, it's gone. Perfectly normal and nothing to worry about.

Nurse Bewbies: Am I the ONLY person in the world who doesn't have issues with Chevy trucks? Seriously. All my Chevy trucks were perfect. Then I bought a Ford. Biggest mistake I've ever made.

Andrew Kandel: Check your manifolds they warp easy and check the fly wheel for cracks. Mine did this for two years till I had enough of it and found both bad

1330ronal: l did this video 2011 now i just did another video check knocking 2002 chevy silverado 2500

jayslay211: is that even a 6.0 looks like a 5.3

abdullah ahmed: maaaaaan it the oil pump if its only appear when the engine is cold you have to change it or your engine will die soon

chevboy94: Its only an exhaust leak cause I freaked over the same thing on the 99 I use to have

Dennis Swew: its not a knock its an exhaust leak, the last exhaust manifold bolt on the driver side is broke off

tracy george: ? i have a 2003 6.0 chevy and love it but i service it like it should be

joeyf504327: For some reason GM uses small oil ports on their lifters and these oil ports get clogged if regular oil changes aren't performed. And also when regular oil changes are performed! Our 2007 Chevy Suburban is doing this, it has 5.3L with AFM. Only thing you can do is use Mobile 1. Or tear down heads and clean the lifters or replace them.

CrownVicKing09: fye wheel

1330ronal: it's beem 2 years and mine chevy still running good i didn't change the oil any more the noise is not too bab the only thing i know this truck dont let me down

Joel P: i have 245k miles too

James89RL: your truck sounds like the exhaust is leaking ...

gst1724: All vortecs have a tick, its nothin uncommom. he is right use GM, Penzoil, or Mobile One fully synthetic 5w30, and an ACDelco filter. It is not a knock or exhaust leak, and no DO NOT use "Marvel Mystery Oil" .....Butcherboy is a freaking idiot. i would love to see him repeatedly change the oil twenty times, the goal of oil is to lubricate and pull dirt, grime, ect. out of the motor. if you dont run the same oil long enough, then it has no time to cleanse the engine system.Also a waste money

Andy Hubbard: how many miles??

clayton cannon: amen never had problems but owned two fords never got 100000 miles out of eather on

anthony king: my 01 chevy 6.0L makes the same sound when it starts up (specially in the winter when its cold) it knocks so loud it almost makes the sound of a diesel engine, but after the oil gets circulated it stops

Tdaz250: Yeah they all do that, especially when its cold out. Mine does it for the first 20 seconds after startup then it goes away

ssjohn70: That's piston slap Ill go away when it warms up...

Kevin Rogers: Well any car or truck if you do the maintance chances are you wont have issues... and for a truck to blow up after a month of owning it, chances are you didnt break the engine in properly and or you just had bad luck simple as that, i work for gm the amount of trucks my dealer sells and for how few issues there are just bad luck

racer650ex: gm says its normal...any 6.0 ive ever heard knocked...the 6.0 that doesnt knock is the one id be concerned about

jayslay211: yea thats a 5.3 not a 6.0.......and it is knocking .......but they will run a long time in that condition

Nurse Bewbies: Dude, your 6 months late. And you don't know crap about what goes on with other people's experience.

MrJeepers22: thats hard to believe

DualsMeatChevy94: @gst1724 if you dont run the same oil long enough, then it has no time to cleanse the engine system.Also a waste money this is not true

wtfracing811: i have a 2002 6.0 and it has 170,000 on it its had pistonslap since the day i bought it nothing to worry about. nice truck

TReaD113: And I believe it. We had a 2000 2500, 6.0, only had 54000 miles BUT it had been through 12 years of abuse..plowing, towing, road trips, etc. Still ran like new

Slednex420: My buddy bought a 6.0 with a tick not quite a knock. Had 197k on it when he bought it. He drove it for 70k miles with it knocking, sprayed nitrous through it, truck pulls, drag race etc. An I still see it driving around. 6.0 is bulletproof. I bought one because of the torture he put that truck through.

DualsMeatChevy94: i believe piston slap bc the skirts are short. does it just do it when its real cold and gradually gets better when warm or all the time?

Joel P: Just worn out lifters, my 2000 GMC sierra 2500 6.0l v8 has has done it for almost 6 years. still runs strong.

TheMarkyGs .: My Original 6.0 in my 2500 went 516000 miles with no Noise at all EVER ! My buddy talked me into a Fresh Crate engine from GM and with in the last 50000 miles i have replaced the engine 4 times Due to Noise issues. The last engine had a Spun rod bearing according to GM..The engine before that had a wrist pin issue.. I change my oil Every 4000 miles ..I wish i still had that old 500k engine..

jimmy101112000: I would like to know why the SES (Service Engine Soon) light is on. That sounds like minor lifter ticking noise. It just might need a valve lash adjustment. Easy way to check is remove the rocket covers and wiggle each rocker arm to find a loose one make sure its not under load or run it without the cover on and push on each one until the noise stops will point out the one causing it. Might not be possible to check when running since some motors will spray oil all over the place.

Nurse Bewbies: When you buy a Ford? You're right.

ucgrad: my 2000 Chevy 2500 knocks like crazy for a minute or so. It's got 5 30 oil. What's the deal?

TReaD113: always happens.

Nurse Bewbies: I have never had issues with GM. Only with Ford. And their customer service sucks too.

Mike Chambers: i too have a 2001 2500 hd with a 6.0 it has the same -piston slap- at start up and it used to start ticking very bad after 8 -10 minutes driving . even though the truck has 250k on it it still runs and drives great other than the afore mentioned issues . i started using gm 5w30 oil and a ac delco filter and this resolved the ticking - lifter - issue. as for the piston slap my brother is a 10 year gm cert tech and he says they all do this . just let it warm up at idle and drive it

BIX KITTY: You need to replace your knock sensors.

davenorr84: sounds great to me.. run it for another 200k then make another vid... chevy ftw!

MrTpengineer: Your funny. Well we had a Z71, it was nice until it blew the engine a month after we bough it! Bought a 2000 f-250 USED and it drove fine for 400,000 miles. We eventually sold it for a stronger truck to pull out 5th wheel. So chevy was our biggest mistake... Don't even get me started on our minivan...
