I have a 2006 TB with the 5.3L V8. This thing has had way more than its reasonable share of problems. I'm on the second $3,000 cylinder head rebuild in 114,000 miles. I have gone through the proper customer assistance channels with Chevrolet to no avail.
I've done some research and I can see that the oil consumption issues leading to engine problems with this engine are NOT unique to me. I am interested in trying to gauge how widespread this issue is. I have a very basic website with a simple form to try gather some information so we can see if this is isolated or common.
If you have experienced similar oil consumption, AFM, misfire, fouled or cracked spark plugs I'd appreciate if you'd get me your basic information via the form on my website. I promise I'm not trying to sell anything or share your information without your approval. I just think that there should be some GM accountability if this does prove to be a widespread issue with these engines.
