#36 of 64 07 cam and lifters #6 die at 60,000 miles POS engine by bigdogsx3

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.

I have 07 LTZ Avalanche. for awhile I complain in a local dealer that my lifters doing allot of noise especially when I start the car in the morning. on top of it the engine loosing oil and not leaking. I had to ad 1.5 quarts after 2k miles of oil change. every single time the dealer would of come and say that they didn't find any problem with the car. I've change a dealer and got the same answers.....I've decided to record on the phone when I start the car in the morning and went to a third dealer near my work and eventually at last yesterday the guy called and said that they suspect the camshaft is no good and they need to get an approval from the warranty on Monday. my avalanche has 93k. since 5 years has expired I've extended the warranty with Zurich Auto Warranty. it's really irritating me that the chevy dealers out there not really has the qualify man power to find such a problem before it's developing to the worse.
