I did a search on this topic and found some good info. Have only had my truck for a couple of weeks and am a little "gun shy" after what I just went through with an 03 6.0 PSD(buy back.) Was wondering if any of you who had this ticking noise finally got rid of it or it went away for good? Is this something that any of you are concerned about long term or should I just let it go and stop worrying?

I can't remember the exact milage but mine went away after a couple thousand miles. I never hear it anymore. Some stay it sticks around but mine didn't. I was getting sick of people asking 'what is wrong with your truck'. And try to explain to some of these people that the wierd noise is perfectly normal...


Definatly let it go and stop worrying!


My dad just bought an 03 Ford with a 6L http://www.dieselplace.com/forum/smileys/Shocked.gif. I hope he doesn't have too many problems. He knew what he was getting himself into.

Thanks Max Power. Just needed a little reassurance. After the nightmare I just went through with that Powerstroke every little odd sound or bump really gets me nervous. Good luck to your Dad. I hope that he gets a good one. I had the rear main seal replaced in mine four times in 7k miles and it was still leaking the day I gave the keys back. Three injectors replaced and the list goes on. Glad to be in a "Real Truck"

My DMAX started ticking around 90 miles. It went away right around 8,500 miles or so. It came back when I did an oil change at 10,000 miles. Now at just over 12,000 miles it has gone away again. No worries...

Mine has ticked since day one, I could care less, it makes good power.

I too have the infamous tick. Many have said it goes away after time, mine seems to like staying. The nice thing is it's really only audible at idle and when I'm near a building(like going to an ATM).

At 7800 miles, the tick comes and goes in my truck. It is deffinetly less frequent now than it was when I first got it though.

Mine has a tick in it, but I have came to the conclusion the only reason I can hear it is because all the other noise is gone. After driving a Cummins for 5 years the Duramax is quite. I beleve a lot of the noise people hear are in the Louder Diesels but never heard them because of all the other noise. This is just my opinion. I really like my Duramax!!!!! Ever try to order a burger from McDonalds Drive Through with out shutting down your Diesel? Well I can with my Duramax !!!Edited by: BIGMoe

I still shut mine off at the drive through.

Shut mine off too but I think it's from too much loud Rock-n-Roll in my dumber days and not the pur of that DMax.Edited by: Bowhunter

huh I cant hear youhttp://www.dieselplace.com/forum/smileys/Confused.gif

Mine has the tick. Talked to a Waste Management guy today driving a company Duramax. He said his tick went away at 10K.

started around a 100 and went away at about 1000 with 4000 even no sign of it comming back http://www.dieselplace.com/forum/smileys/Clap.gif

Just got back from Wyoming, around Jeffrey City, Muddy Gap, on an antelope hunt. Saw alot of the highway crews and state construction guys using Duramax powered trucks. Bought mine two days after I got back. If those guys trusted them in their work environment, how could I go wrong.

The tick can be annoying but it's a non issue.

And hoot is a tick expert! Think about it, with 1270 posts in around a month all he hears is tick, tick ,tick on the keyboard! http://www.dieselplace.com/forum/smileys/Clown.gif

33K and mine still ticks now and then. Running Delvac 1 last 20+K. Heard it yesterday while idling next to a building. I love the tick, reminds me the engine is still "Tight" LOLhttp://www.dieselplace.com/forum/smileys/Cool.gif

And Peanut hears:


TICK TICK TICK

I have that same tick in my 03 D/A with 4500 miles on the clock. I have read in a couple places that the Mobil 1 Delvac synthetic oil takes care of it for some people. I will be switching to Delvac synthetic at 10K, guess we will see if it goes away then.


Curtis

11000 sum odd miles and mine ticks. Keeps a pretty good rythm to. I had the dealer look at it just so there would be a record of it incase the General decides it is bad thing down the line. Then if the motor goes bad and tick is gone at the time I will be able to say, But look I had it at one time.

Mine used to have the tick. Went away at about 8,000 miles or so. NOW, my truck has a tick/knock on the passenger side that I could never hear before over the tick on the driver's side. It's quieter than the tick was, but something's there. I remember reading that it could be a loose or misaligned donut on the exhaust downpipe. I've checked that, it all looks good. I don't think that it's anything to worry about...


cadman_ks

I dont know if I have any unusual noises. After my ford
nightmare all I do is drive this great truck and smile
and wonder why chevy kept the d/a a secret. This truck handles like a sports car. First truck Ive had ever that absolutely did not need to go back to the dealer for something. Changed fluids; white cap already on 04, my
trans dip stick has a lock also. This site is soooo
good.http://www.dieselplace.com/forum/smileys/Clap.gif

Mine starting "ticking" immediately after the first oil change (4K). I was somewhat worried about it, but it seemed like it was exactly as described in the TSB (i.e. random ticking from driver's side of engine, mainly heard at driveup windows and ATMs). Still ticking (last time I pulled up to Sonic Driveup window!) at 7300miles.


After listening to my friends brand new 6.0L PowerStroke, I'm certainly not going to complain about a little "ticking". His sounded like someone was beating on a 55gal barrel with a ball-peen hammer when he started it!

Mine had it from day one,dissapeared at about 25k miles. I kinda miss it .

I GOT THE TICK TOO.

My truck was a GM program vehicle so it had 7500 miles on it when I got it (never mind it was my mom's company carhttp://www.dieselplace.com/forum/smileys/Big Smile.gif). I now have a little over 49K on it and it still has the tick. I've had it since day one, haven't figured out what it is yet but, no problems from it.

Mine had tick at 100 miles, went away at 15000, came back when dealer changed oil at 34000, all but gone at 37000. Tried Rotella synthetic at 10000 made no difference. Know of a guy with no tick until 60000 now he has it. Really not a big deal IMHO.

After further review I guess I do not have the Tick. I was walking past a friends 03 GMC Duramax and his had a tick that mine does not. It is noticable, but I don't think I could of heard it in the Dodge /Cummins I had. If it would of had one!!!

I had the tick. Started around 6000 miles on the engine. Changed oil and filter at 9900 miles. It's gone. Changed the oil to Rotella Synthetic 5W-40 from Delo 15W-40 and the filter to ACDelco from a Wix.


Now it's driving me crazy... was it the oil or the filter that was causing the tick?Edited by: JohnnyO

My tick was gone at about 4000 mi. however I still catch a slight tick on cold mornings.

I have the tick. Only 500 miles on her. A buddy has one and says it will go away not to worry. So what is the official word from GM? Or should we all email them with the same thing?http://www.dieselplace.com/forum/smileys/Ermm.gif

From previous posts you can see that so far the "Tick" is a non issue. Mine still ticks at 33K off and on, heard it again yesterday at a red light.


Lots of trucks now getting up close or just over 100K. No repots of any "Tick" related damage. Have not seen 1 report of anything remotely related to the Tick noise. You can be sure if there was anything resulting from the Tick it would be out on the wires faster than JLO's and Ben's wedding!

GM CB#02-06-01-022B dated 10/27/03 (supercedes GM CB#02-06-01-022A)


I too have a tick in my 04 Sierra 2500HD D/A CC SB. I noticed it after the initial oil change @ 1K miles. Today I met with my service advisor who researched the conditon and found the above GM Corporate Bulletin linked to the issue.


I had to check, I just traded my 01' GMC Yukon Denali with the 6.0 that had a bad "piston slap" problem. During initial start-up, you would think I had D-Max under the hood. As a MOF, I had someone approach me in the airport garage after the truck was there for a couple days and ask me when GM had added the D-Max to the Yukon!! Not a pleasant experience,,


The CB reads:


It states some vehicles may exhibit a random ticking noise that is most audible on an engine with a coolant temp. of 70 deg. C or higher and from idle to approx. 1500 RPM. The noise is usually most noticeable at the rear of the driver's side fron wheel well.


In summary, GM states the condition is caused by the relationship of the engine cylinder block, crankshaft journals, bearing inserts and the oil film. The relationship may allow a vibration that resonates through the cylinder block and is heard as a metallic ticking noise. The noise could be best described as an irregular tickingand clapping sound, like random typing on a mechanical typewriter.


It goes on to say the condition has been present in diesel engine designs from many manufacturers for over 20 or more years. Recent improvements and reductions to diesel noise levels make the noise seem new when, in fact, it was masked by other noises in the past.


Testing and engine teardowns with this condition reveal no condition that would affect reliability or durability of the engine.


GM advises that dealers should not attempt to compare customers vehicles exhibiting the noise with other similar vehicles as the noise is different vehicle to vehicle. The noise and a normal characteristic of the engine and they are not to make repairs for this noise.

Is it possible this ticking noise is caused by the mechanical valve tappets! With 32 valves running in there I figure your bound to hear some ticking.


Has anyone ever had their valves adjusted to try and quiet the tick?


When is a valve adjustment required on the Duramax?


Mine ticks to(2300 Mi).

I have the infamous TICK on my 2004. I test drove another 2004 for a few days before buying mine and it did not have the tick. I am still concerned that some have it and some dont and people say it comes and goes. I love the truck but the tick does bother me.

My truck did not have the tick when I brought it home. I changed the oil & filter @ 900 miles, the tick appeared @ about 1050. Now, @ 2250, it is gone again. I expect it will be back. I don't think it is anything to worry about.

The tick is a cracked wrist pin.
Your engine is about to explode. :)

Gm says everything is normal and will not cause longevity issues. You could be dumping 5 qts of oil per 3k miles with a loud knocking rod and gm would say its normal.

I have the tick too.

Problemchild, that was a little uncalled for. I realize you have crappy luck with any vehicle you have ever owned, but to bash GM like that...?


The ticking noise is not a problem issue, it will go away with break-in miles. Also you need to keep in mind that the DMax is MUCH quieter than any other personal diesel on the market, so by comparison the DMax will pronounce any ticking noise that others cover up with the normal diesel noises that they have........The DMax runs quiet enough to actually hear a tick! The rest of the smokers just rattle all the time!

Be glad you have the Tick, it means your engine is still "tight" and breaking in........When the "Tick" goes away for good, things should be loose!

So with all the "knowledge" on this site thats the answer, don't worry about it?? Does anybody "know" what the ticking is? I would feel alot better about the whole thing (as would others I'm sure!) if somebody could actually tell me what the ticking is. To me it sounds like a spark jumping a gap somewhere, but what do I knowhttp://www.dieselplace.com/forum/smileys/Big Smile.gif

TOTALLY DIFFERENT ISSUE.....not related to our "Tick"


There's a TSB "No Action" report out there. Do a search and you will find the actual report. As I recall it the "TicK" is due to tight clearance in journal and bearing surfaces and high oil pressure in the DMAX. We have several high mileage trucks all with the tick and no directly related problems. As I understand it, once high mileage accumulates and these surfaces wear a little the tick goes away.


This subject has been beat to death since first DMAX engines were sold in 2001. I realize it is something new to the new owner's and aggravating in a $40K or less truck, but it has been there in most trucks at one time or the other. Sometimes an oil change (brand) makes it go away or show up more prominately.


You can believe one thing if you don't believe anything or anyone else, The first second something happens to someones truck and it is blamed on the "Tick" it will spread here and everywhere else like wildfire. So far not one report of a tick related problem anywhere.


That's why some of us say "don't worry about it". Realize that's hard to do in a new truck that sounds like someone is hammering out a letter on an old Underwood when stopped at a light or next to a sound wall somewhere.


For now as said before "My truck takes a lickin and keeps on ticking"

This bulletin is being revised to update the models information. Please discard Corporate Bulletin Number 02-06-01-022A (Section 06 -- Engine/Propulsion System).


Some of the above vehicles may exhibit a random ticking noise that is most audible on an engine with a coolant temperature of 70°C (158°F) or higher and from idle to approximately 1500 RPM. The noise usually is most noticeable at the rear of the driver's side front wheel well. Customers may also comment about hearing a tick noise inside the vehicle at idle such as when sitting at a drive through window. All 6600 Duramax™ diesel engines have this condition; however, some are more audible than others. Engine build variation from engine to engine contributes to differences in perceived volume. All Duramax™ engines are manufactured to very close tolerances to meet the durability and reliability standards.


This noise is caused by the relationship of the engine cylinder block, crankshaft journals, bearing inserts and the oil film. This relationship may allow a vibration that resonates through the cylinder block and is heard as a metallic ticking noise. The noise could be described as an irregular ticking or clacking sound, like random typing on a mechanical typewriter.


This condition has been present in diesel engines produced for the last 20 or more years. The overall noise reduction in engines produced today makes this noise seem new when, in fact, it was masked by other noises in the past. Many manufacturers such as Isuzu, Hino, Mitsubishi, and Nissan report a similar condition in their diesel engines. Testing and engine teardowns with this condition reveal no condition that would affect reliability or durability of this engine.


Dealers should not attempt to compare any customer vehicles exhibiting this noise with other similar vehicles as the noise is different from vehicle to vehicle and this may lead to the incorrect conclusion that the vehicle has a condition. This noise is a normal operating characteristic of the engine. This noise has no short or long term effects on the engine. Do not attempt repairs for this noise.



<H4>Important</H4>


Replacing the engine or internal components for this noise will not reduce or eliminate the noise.

Thanks guys...8500 miles and still tight!! Shell Rotella 15-W40


Maybe we should do a poll and find out what oil makes it go away, I don't know if I want it to go awayhttp://www.dieselplace.com/forum/smileys/Confused.gif
