    Whats up guys, just got a new toy. 2002 silverado HD 6.0. Only 65k miles and garage kept. Its beautiful and its in mint condition in and out. Only thing is im getting a clicking sound coming from the engine, sounds like its coming from the bottom front of the engine. I literally just got this yesterday, and have not had the chance to see if it fades or stops as the engine is cold, warm, or at running temp. Sorry for the lil info, just trying to see if there is a widely known issue, my first silverado. Its not terribly loud but its not quiet either. Thank you for any feed back.

    Welcome to the club, Gorg. Is your truck 2wd or 4x4?

    There are Couple.....G.M. TSB.....Regarding......Clicking/Ticking and/or Piston Slap on the Silverado's,

    Here is one those G.M. TSB.....that may or may not apply to the noise you are hearing coming from your Silverado,

    Condition........Some customers may comment on an Engine Tick Noise. The distinguishing characteristic of this condition is that it likely will have been present since new, and is typically noticed within the first 161-322 km (100-200 mi). The noise may often be diagnosed as a collapsed lifter. Additionally, the noise may be present at cold start and appear to diminish and then return as the engine warms to operating temperature. This noise is different from other noises that may begin to occur at 3219-4828 km (2000-3000 mi).

    Cause......The 0-ring seal between the oil pump screen and the oil pump may be cut, causing aeration of the oil.

    Correction.......Inspect the 0-ring seal and replace as necessary. Use the applicable part number listed below. Refer to the Engine Mechanical sub-section of the appropriate Service Manual.

    thank you for the info, im gonna try checking that o-ring if switching to synthetic motor oil and adding some fuel injector cleaner doesnt work, I was informed both could possibly solve the problem. Just so happens im mechanicaly inclined so I am starting there and will try each solution i come across till I get it. Where can i find articles like the one you refrenced to?

    Thank you for any feed back.
