2002 Chevrolet Truck Silverado from North America - Comments

Unfortunately I own a 04 GMC 2500HD. The knocking noise is there, but it is buried by the leaking exhaust manifolds. As a result of poor engineering, the manifold casting is far too slight and the manifold bolts are that small that they will actually snap off while driving. This is a regular occurrence while attempting to tow a trailer. The truck is rated at 10,000 lbs tow capacity, and my trailer is 6500lbs.

The GM dealer just advised me that the problem will only be cured if I modify the exhaust system. If anyone is considering buying one of these engines, check all facts, I wish I did.

I have a 03 1500hd with the 6.0 and it sounds like it's going to fly apart when cold. Sometimes it quits for just a second when you put it in neutral then back into drive, but then the knocking starts right back up. The truck has 103000 miles and seems to have good power and uses no oil. I took it into the dealer and they told me a lifter is shot and the cost would be 800 dollars and be only a temporary fix. I should buy a new motor for 5000 dollars. What a bunch of crap to spend that much on a truck that only books for around 13000!

I have a 2002, 2500 HD, crew cab, 4wheel drive.

I have never had the knocking problem that so many have made a comment about. However... the problem that I am having is that the truck dies for no reason while driving normally. Just shuts off like the key was turned off... After I turn the key off and wait for a few seconds, it starts right up and continues on with no problem.

I took it to a private mechanic that I trust and he could not find the problem.. he could not make it fail and he said the truck on board computer showed no failure codes. One comment that I have read, quoted the same problem with the dealer not knowing what to do... any help or comments...? Sep 6, 2002, Don.

I have the same knock in my 6.0; it's annoying because sometimes it sounds like valve-train noise, and sometimes it sounds like a rod knock. It's like a game; I get out and listen to it through the drivers side fender well because it's not coming from the passenger side or under the hood. With this knock and the transfer case pump rub, I am no longer a Chevy fan.

I have 130,00 miles on it and it has been taken care of with synthetic oil every 3,000 miles. I feel robbed. A Toyota with the kind of care that I have given this thing would run for a 500,000 miles with no problem.

I have been a die hard Chevy guy all my life. My whole family works for General Motors.

I just bought an 05 Silverado Z71 with the 5.3 engine. Runs great with no problem other than the constant knock at idle once it is warm. Very embarrassing.

I have held the thing on the rev limiter to try and blow it up... Won't blow. It runs mint and knock goes away right as soon as you get into the throttle??? What gives? I have no idea what it could be.

I have spun a lot of rod bearings in my time as I used to build and race early Camaros. It sounds like a rod knock for sure. Usually if it is a rod knock, it will re appear under load at certain rpms... Any info would be appreciated! mike@theautodreamgroup.com

I have a 2001 2500hd with the 6.0. it has 107,00 miles. I only have the knock when I start the truck in cold weather. from 32 degrees and below. it also uses about a quart of oil between oil changes which isn't that bad. I love the truck it drives great and pulls great I am hate the knock though. I hate to start the truck around people when its cold. everone notices it. if anyone knows a fix for this let us know.

I have a 1993 Suburban 4x4 3/4 ton 5.7l with 4:10 diff 200.000km. It gets 1000km per tank, hwy 20mpg, does not burn oil at all or make any noises when cold, but it's not the most powerful truck when towing.

I'm looking to buy a 2000 to 2005 Chev 6.0L, but after reading some comments about the 6.0L I'm not so sure, maybe a guy is better to buy the old 6.5 turbo diesel; at least they are supposed to make noise.

Hello, I am true Chevy fan and have owned many Chevy trucks. They have always gotten the job done and did everything I have asked for.

I believe the 5.7 350, 7.4 454, 5.0 305, and the 4.3 262 engines are the best out of all series, due the long history, reliability, and cheap parts.

I own a 5.3 and 6.0 engine trucks, I have noticed the 5.3 is alway quiet no problems, the 6.0 is a little noisy at cold starts in the morning, but not a problem as the oil is circulating the engine.

They don't burn oil or leak, so for most part I can't complain about the engines. I do however use 10w-30 instead of the 5w-30 with no additives.

I have a 2002 Chevy 1500HD with the 6.0L with 130,000 on it. In the last few months it has started to get a knock coming from the #1 cylinder. The knock will happen all the time. I changed the oil, hoping that that would help, but it did not help.

Then the knock went away and it started running very rough and it dies, check engine light comes on, loud sucking from the air intake. I pulled the valve cover and looked at the valve springs, they looked good, then I did a compression test on it and had good compression on all but 0 on the #1 cylinder. I don't know, any ideas??? brentwhlr@yahoo.com

I have a 2001 1500 Z71 with 193000 miles. It's the 5.3. Knocks when started cold too. I use 10w30 with one qt of Lucius. Never had a wrench on it for repairs, knock on wood. Great truck, minus the start up noise.

I have a 2002 Silverado 2500HD that I bought new, and it has always knocked after about 20000 miles. It now has 230,000 miles. Love my truck, always kept up with oil changes and runs like a champ, with or without the engine chatter. Very dependable truck.

I have a 2002 Chev truck. When I first start it in the morning, it has a knocking noise coming from the engine. I talked to a mechanic about it and he said it’s normal. He also said he had one just like it and it also knocked when he first started it. He when on to explain to me that Chev had built the engine with under size piston to reduce friction. If this is true, I am here to say they messed up. No more Chev trucks for me.

ROFL...I bought a new HD 2500 4x4 with the 6.0, in 2002. It now has 53,000 miles on it. Mobil 1, and K&N filter since first oil change at 1,000 miles.

I just did a full service on my truck. All fluids changed, and ECB brake H. P brakes. I'm a Chevy mechanic.

I have never dogged my truck, but I do run the crap out of it. Ha!

I have never heard any knocking, period. My 6.0 pulls like a horse, and it runs hard always. Period...
