I have an 02 Sierra Denali QS, 6.0L, 45,000. When cold the engine sounds like a diesel, lots of chatter? Any ideas? Thanks.

Welcome to the club.

When cold all of my LS1 (in the trucks) motors have ticked and sqweeked. Usually a belt and/or a tensioner takes care of the that. The chatter should stop once oil gets into the lifters. If it persist after warm up I would get it checked out. Assuming you have checked your fluids and what not.


03 QS Arrival Blue, 6.0, Leather, Heated Seats, True Duals.SOLD and regretting it. Project car 67 Camaro.
