Every morning when the vehicle is started there is a "clicking" noise. It increases in speed with RPM. Once hits 2000 (or so) RPM, noise will stop. Noise will also quit after 5 mins of idle. Cannot determine cause. Happens regardless of outside temp, however is better in AZ summer months. Mechanic cannot find source of the problem. All ideas/solutions welcome.

Purchased brand new 2001 Chevy Tahoe and within first 3 months noticed oil level was lower than expected. Began 'oil consumption' test with tracy dealership that extended into 2004 until they finally agreed 2 tear down the engine...all 3 years was ongoing oil loss within the engine! they only went 2 the cylinder heads despite several requests by expert mechanic's advice 2 go further into the piston level. Tracy Chevrolet reported their findings as 'parts missing from cylinder heads from original engine assembly'. GM's CEO promised 2 replace my engine if the oil consumption wasn't fixed. Within 1 month of that repair, oil loss continued. Another 'oil consumption' test scenario was established and another 3 years passed with me reporting 2 them every 500 miles for oil level checks. Again, 3 years passed before they finally decided 2 tear the engine down again. (3/7/07). The cylinder heads were fine so GM recommended that they go down 2 the piston level (sound familiar??) where they found another missing part from original factory assembly! (oil control rings) they tried 2 have me accept they were doing me a favor as I was now out of warranty. I had 2 remind them that I reported this 2 them well within my 1st year, they were responsible for delaying appropriate repairs, and now, this engine was probably missing other parts. I was holding them 2 their original promise of replacing my engine. The CEO's office has it well documented yet they are going back on their promise and want me 2 just keep an unsafe, unreliable engine. They can't guarantee that other vital parts aren't missing and I doubt any of them would feel safe with this engine. Can you tell me what damage has occurred 2 other engine parts due 2 this extensive prolonged oil loss? they refuse 2 provide any further assistance, information, or my replacement engine. They are offering me instead 3 free oil changes for 6 years of worry, inconvenience, and enduring their complacency with this safety issue.
