2008 3.6 dead @103k miles

[cavell]

Why can’t gm make a good 3.6 motor? Seller only has 103k miles and motor is dead. New 18” tires. 100 miles. Wants $800
i work on 3.4 motors only.

 

[Hey Vern!]

I just watched a video by a guy at a scrap yard. They had 3.6 powered cars everywhere. He was saying that some aren't even making it to 100,000 miles and most will not last past 120,000 miles. sad.

I’ve heard replacing the chains is a lousy job. would hate to spend $400 on kit and find out motor has more issues.
I am doing heads on a 3.4 now and have a 2nd lined up. Really don’t want to try a 3.6. Though, new 18” tires/wheels sounds nice.
