Why does my Chevy Silverado knock all the time?
It will also knock after the truck has been sitting for a half an hour, so it is not really a cold engine knock. I have about 6,700 miles on this engine and this is the second engine in my 2000 Silverado. GM replaced the original engine at 15,900 miles for the same reasons (knocking and tapping).
Why does my Duramax make a heavy knock sound?
It also doesn’t run unevenly making the vehicle shake when it’s cold (runs smooth,) but at the same engine RPM when warmed up (to normal operating temperature or at least blowing out heat from the vents) it makes a very heavy knock sound that scares me, it’s so loud. I let the vehicle cool down (it’s 15 degrees f) and tried it again 2 hours later.

The dealer did a GM-recommended “decarbon treatment” which did no good. The truck now has 15,000 miles and the knock is getting worse – even happens some when the engine is warm.
