In this article, updated this past January, the author outlines the 4 most common issues with our engines, except he seems to get it wrong in my opinion. Seems to me turbo issues are number one and emissions issues number two.

The 4 Most Common Ford 3.0 PowerStroke Diesel Engine Problems

4 Common 3.0 PowerStroke Problems
  • Crankshaft Bearing Failure
  • EGR & EGR Cooler Problems
  • DPF Clogging
  • EGT Sensor Failure

We’ll be diving into each of the problems in-depth throughout the post. Crankshaft bearings were notably an issue on previous 3.0 diesel engines from Ford. However, the new 3.0L version received a handful of updates prior to joining the F-150 and Powerstroke engine family. Time will tell how these engines hold up in the long-run, but emission part issues are common on nearly all modern diesel engines and especially these newly designed mini-diesels.

That said, we’re also focusing on the most common problems. It doesn’t necessarily mean they’re actually common. Rather, when problems do occur these are a few of the most common areas that they occur. With that out of the way, let’s jump in and discuss the above faults and failures in greater depth.
Bearing failure is a small number of reports here, I think. He may be referring to the earlier Lion engine before they beefed up the bearings for the F150. He also does not list turbos in the top 4, but I think they may be.

From the linked article:
This issue is purely speculation based on failures in the previous generation of this engine. However, these were problems before Ford redesigned the engine to be used in the F150. Fortunately, it doesn’t seem the crankshaft bearing issues are occurring on the 3.0 Powerstroke. It’s worth the mention, though.
Purely speculation & worth a mention but it is his #1 issue? This guy has zero credibility unless he is going for click-bait!

I would say that turbo issues aren't really a thing, just the charge air pipe leaking. Many turbos have been replaced un-necessarily due to that. and yes the crank shaft failures can happen, but they're rare, and seem to happen only to those running 5w30 FA-4 oil. That said i have only seen one, maybe two happen, which are likely due to a manufacturing defect in the shaft forging process, or a defect in the block design allowing the shaft to shift. This will announce itself early on, so if you've made it past warranty, you probably have a good shaft and don't need to worry about it. It was definitely an issue on the pre-2018 versions.
