Blue Oval technician and YouTuber Brian Makuloco has long been keen to provide us with a wealth of information regarding ways to identify and repair common issues with a variety of vehicles and powerplants, but at the same time, he also puts out quite a few videos showing us various common problems with Ford EcoBoost engines, specifically. It’s a pretty well-known fact that many first- and second-generation versions of the Ford EcoBoost family have plenty of common issues that owners (or shoppers) should look out for, and now, Makuloco has identified yet another one.
This particular problem pertains to the roller followers in the second-generation twin turbocharged Ford 3.5L V6 EcoBoost engine, which was used in a wide array of models over the years. The second-gen 3.5L EcoBoost uses roller followers instead of the direct acting mechanical buckets present on the first-generation version of that same engine, but unfortunately, those components are also apparently coming loose over time and “chewing up” the outer portion of the cam lobe that they come into contact with.
Roller followers are also a weak spot on the old three-valve 5.4L V8 Triton engine, and some have experienced this type of issue on a select number of 5.0L V8 Coyote engines as well. Makuloco notes that he’s starting to see it pop up on the second-generation 3.5L Ford EcoBoost V6 now as well, which is obviously not great news for owners, who should be aware of it before it’s too late.
This is just the latest common Ford EcoBoost issue that we can add to a rather long list – including heavy coolant consumption with the 2.0L I-4 EcoBoost, as well as many related to the 3.5 – such as exploding internal parts, excessive carbon buildup, phasers, and even complete failures that can result from engines that are tuned aggressively.

And lets not forget about the millions of 10r80 transmissions exploding everywhere !
In G M and Ford
I’m spotting a pattern here …
That kind of comment sounds familiar JB. (JustBu_____t).
Ford needs to fire all there engineers and start over. They are going to bankrupt the company.
With so many good makes out there it never ceases to amaze me how ppl still buy FORD vehicles – it’s the Boeing of the auto industry.
