Where does the ticking noise come from in a Duramax?
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.
Why does my Chevy Silverado make a tapping noise?
The engine has a deep knocking noise in the lower part and a tapping noise in the upper part . The engine has a miss at idle and no matter how much diagnostic equipment you hook up to the truck you can’t find the reason, but after checking I have found that all the 99 and 2000 silerado’s with the 5. 3 have had a strange miss/vibration.
Is it bad to hear piston slap in Chevy Silverado?
In TSB 01-06-01-022 (Aug 22, 2001) and TSB 01-06-01-028A (Mar 18, 2003) GM has stated that piston slap is not detrimental and will not affect the service life of the engine.

What causes a Duramax injection pump to fail?
As a result (allegedly), the lack of lubrication in the fuel can cause a premature failure of the injection pump, to a point where it won’t allow the LML Duramax to run. You can be driving down the road and everything seems normal, and when the pump fails, the truck just shuts off.
