I realize this is an older post but thought I would let you in on a current experience that I am having with my 09 Avalanche...I love the truck but have had the oil pump changed at 75K miles via the dealer warranty and had the same chirping sound...turned out to be the cam shaft and lifters...again replacedat 98K miles by the dealer warranty. I have owned the truck since 8-5-09 when I purchased the truck with 5 miles on it...I have driven over 93,000 miles in the 2.5 years that I have owned the truck..lots of highway miles...I have used Royal Purple 5W-30 oil as recommended every 7K miles... I just pray nothing else goes wrong....its still not paid for but the service warranty is about to expire...
 
I have always driven a GM product...I own 5 other Chevy trucks with 5.7 litre motors but have never had these types of engine problems. I love the gas mileage...my AV is a 4x4 and has never left the highway...and I get 21.5 on the highway and 18-19 in the town driving...If the engine proves reliable I would like to own another Av as my dealer states that GM will discontinue it in 2013.

I am an auto mechanic with 32 yrs exp. I got my 07 avalanche with 30 thsnd miles on it, and have changed oil every 3 th with synt. oil. I service ALL my vehicles with top notch parts, no 2nd brand crap... The engine threw codes for #6 injector, i replaced, no difference, Took off head and #6 rocker arm didnt move. Took to GM and even tho they SEE the engine is clean, wont repair. 1 month outta warranty, just turned 60 000 miles, THEY know there is a problem, becasue there was also another 07 in for the exact same thing the same time as mine. I am going to fight GM for them to fix this. THIS is the reason i will NEVER buy GM again My Nissan pathfinder 225 thousands miles on it and you cant even hear it run.... has anyone gotten it fixed on GMs tab?? this is ridiculous. You pay 50 tho for a truck it shouls last more then 60 thous miles. And my truck doesnt pull anything, Godforbid i have to haul my horses somewhere, then what..... any help from anyone whose had this same issue. i am sure i am not the only one.

I bought a new 2010 Avalanche that came with a 6.2 "cadillac engine"..I only have about 7000 klms on it..It sat for a few days and when I started it up a lot of blue smoke came out,,oil would be my guess,,has any one else had this problem??

I have a 06 avalanche with the 5.3L It started that chirping a couple of weeks ago. Has 94K miles and I alway's changed the oil regularly. 5k miles. I'm going to look around and see what may be a better oil to use. I have been using castrol 5w 30. I'm going to buy a used engine from a friends salvage company and maybe rebuild my old engine myself. I'm going to have the heads done to boost horsepower and do a camshaft upgrade maybe from summitt. I can easily add 100hp by doing that. Seems a hydraulic roller lifter has messed up knocking a lobe off the cam. I had a lot of fine metal in my oil pan. So I know how you feel. It sucks.

My Chevrolet Avalanche did same thing on 10/2/12. I was driving down the road and the motor started knocking like a jack hammer was inside of it. All the lights came on which were engine light,traction control, stability control and something else which i cant remember. The truck lost all power and i thought it blew up. My Avalanche is a 2007 LTZ fully loaded with a 6.0 motor. Called Gm and they were very helpful. Took to local chevrolet dealership and diagnosed with # 4 cylinder misfired and lifters were broke or locked up and cam was damaged. They are replacing all lifters and new cam in it. Had to show records oil changes but GM gave me no questions after that. Pick it monday. Goodluck and hope they paid for yours also.

02 avalanche very hard to start on the first start. acts as if no fuel...starts rough and after pressing hard in the gas, will finally lever out and run smooth. I'm guessing a bad cold start sensor, but what do I know. any ideas?

I would like to get as many people with the same problem
and try to get a recall on this issue. and for those who had
paid get their money back. my Avalanche has only 57,700 miles. I bought it new.
the dealer will pay half wich is close to 1,100. the noise is getting worse.
