New here and looking for some guidance. I've been keeping up with the forum and really appreciate all the information everyone shares but I think I have information overload.
I just sold my 2014 ecoboost f150 with 68k miles after getting tired of repeated timing chain, IWE, and coolant leak issues. I am now looking for a Sierra that I can keep until it either becomes too troublesome or expensive to own any longer (hopefully 8+ years). Based on what I have read and watched, and my own experiences test driving vehicles the 6.2 and the 3.0 have the performance characteristics I am looking for. After using the search function here and elsewhere I am aware of the seemingly few issues these engines are having (such as valve springs for recently built 6.2's, and DEF consumption and cooling fans for the 3.0). Here's where I get stuck and I am hoping you all can provide some input: I found two vehicles that fit my needs/wants, one with each engine. I am concerned about the 6.2 because it was built in the timeframe related with the bad batch of valve springs and with the 3.0 being so new I'm leery of having gremlins start popping up after the first XX,000 miles (like with the ecoboost I just disposed of).
So, I guess my questions boils down to: Would you let the valve spring TSB dissuade you from purchasing a 6.2? And, how much faith do you have in the 3.0 as far as long term durability?
