Typewriter tick.

 

"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."

 

Head to the dealer and see if they will print you a copy of the bulletin.

So the bulletin is saying its normal? There is no dealer anywhere near where I am

 

 

Maybe the user that is a GM customer service rep here can fax that bulletin to you? Or even email it.

Has your concern been resolved? Unfortunately I am not able to provide bulletin information. I would have to recommend giving your local GM dealer a call. They may be able to mail or fax the bulletin over to you. Let me know if you need anything else. Thank you.

 

Tricia, GM Customer Service.

Yes my issue has been resolved...somebody posted up the bulletin stating that a typewriter ticking noise is normal in diesel engines. Thank you

Yep, normal and should go away in a few hundred miles. I am 70k on the clock and strangely mine did it for the first time the last oil change. I have wondered if it wasn't the different oil filter I used.

Friend was just over the house yesterday afternoon with his 2011 Chevy K3500 D/A E. Cab long box (bought last July of 2011). Has 24,000+- miles and has been using nothing but AMSOIL DME 15W-40. We could not hear anything like this on his truck. He also uses the AMSOIL EAO52 Oil Filter (he is a Dealer). So far he has not had a lick of trouble with the truck, he tows a travel trailer. The OLM monitor has just gone off in his truck and he was heading to get the oil changed, said it was at 9,000 miles when the OLM went off.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      New member here. I am researching a read-first event-recorder concept for late-model GM V8 trucks. This is not a sales post. There is no product link, price, preorder, or mailing list. I am trying to determine whether the underlying problem is real before building anything.   Has your truck ever had a brief problem such as: - rough running or a momentary misfire - an oil-pressure warning or unusual pressure event - reduced power or a brief stall - a U-code or lost-communication problem - a symptom that disappeared before the dealer or independent shop could reproduce it   If so, I would appreciate the following details: - year, model, engine, and mileage - what happened and under what conditions - whether a DTC and useful freeze-frame data were stored - whether the shop was able to reproduce it - what the eventual confirmed repair was, if known - what additional information would have helped the diagnosis   The concept being evaluated is a removable leave-in recorder that continuously retains a rolling window from before and after an event. It would not tune, reflash, clear codes, or change the vehicle calibration.   I am also not claiming that it could predict lifter failure or see every internal ECM variable.   The real question is whether continuous event history would add enough useful evidence beyond freeze frame, GDS2, and existing scan tools — or whether it would simply be another unnecessary gadget.   For owners and technicians, which problem would make something like this genuinely useful: 1. intermittent misfire or AFM/DFM-related behavior 2. oil-pressure events 3. lost communication or electrical faults 4. none of the above Please be blunt. Negative feedback is just as useful as positive feedback.

      No tears over the SLE and SLT trim levels disappearing but I kind of loathe the "Elevation" name. It's a truck--skip the elegance.   The slab-dashboard design is decidedly different. Almost has a Hummer flavor to it. "Professional Grade" seems to be leaning very white-collar, tech-driven these days moreso than blue-collar, functional design.   The Silverado would be my choice between the two new trucks. Pleased with the engine lineup in both. The GMC is a little "too much" for a truck, IMO, and the Denali borders on ridiculous - but I do know there are buyers for luxury trucks out there. It's just not my speed.

      - I like the outside but not as much as the Chevrolet.  They ICE'd the EV styling and it works, but I think exterior goes to Chevy on this one.     - SLE and SLT dead = Not.  Surprising.  Fits into the rest of the GMC lineup like this which (aside from Pro) matches the rest of the family.  Elevation, AT4, Denali.     - Interior.  Sophisticated Malaise era.  Why do I say Malaise?  Drawn with a ruler.  Rectangles everywhere.  Looks very premium though.

      I may be old school. But I’ll pass. I’ll stick with the old stuff. Thank you.
