I recently bought a 2014 Sierra SLT with 79,000 miles on it. It’s a beautiful truck, well maintained and in excellent condition.
When I was looking for a truck, I found a whole lot of 5.3 & 4.8 Ecotecs with well over 100,000 miles, many with over 150,000 and one with 200,000+ miles. Most seemed decent but I bought the one that I thought was the best for me.
However, upon reading the posts on this forum, it almost sounds like every time I start it up I have to worry about the AFM lifters taking out the cam. I’m thinking I’m on borrowed time waiting for the engine to explode.
It it really that bad, or just the fact that owners with problems are the only ones posting?? Should I just go ahead and spend thousands of dollars to remove the AFM stuff? Should I not take any trips over 50 miles?
Anyone have a solid motor with 100,000++ miles???
