Ford F150 3.5L Ecoboost Rattle Upon Start Up- Timing Chain Stretch Issues
Ok so some may know about this some may not but it is something that is coming on strong with many showings at dealerships across America. So as most know it is timing chains that are prematurely stretching causing this startup noise. The news is that there is updated parts out there to address this and Ford now has a TSB on this issue formally admitting to it being a common problem. I go over it all in this video. There is also a link to just how it sounds in the description of the video on youtube. Hopefully more dealers will be willing to dive into the engine with some guidance from Ford now.
I think it's good that there's a TSB for this. It shows that Ford is acknowledging the problem.
What I really want to know is what is causing the stretch?? Are oil change intervals too long? Should we be using full synthetic oil instead of semi? Is the chain starved of oil somehow? All the above? None of the above?
I really want to avoid this, and if I get it, and have the TSB done, I want to avoid having it again.
