Hello,

I am hesitant to even make this thread because it seems like such a freak rare thing to happen. Put I wanted to share that my 2021 Tremor with 50k miles is getting a replacement long block due to a spun rod bearing in cylinder 4. I have to say that Ford Country has made this as convenient as possible. They even got us an F150 so we didn't need to change upcoming vacation plans as well. Things happen and break, the service experience has been solid though.

I was always worried about putting a tune on the Ranger should something like this happen, so thankful I did not otherwise I might be SOL. I asked the foreman what if it was tuned, he said they would have had to prove it was the tune, which was actually cool to hear. He told me he ran a tune on his 5G Ranger and might on his 6G Raptor too. He told me you just never see this kind of failure on the 2.3L with a well maintained engine.

The day the knock happened was just another day, driving down the road and around 2500-3000rpm a knock was heard under moderate load right before the shift. I was still accelerating to 50mph when it happened. Let off the throttle immediately and got back on it, knock went away and came back. With light throttle (probably no boost) I could work my way up to speed without the knock. Got an appointment at the dealer the next day.

-5k full synthetic oil changes
-never tuned, only K&N filter
-coolant flush done around 45k (by 50k both diffs, trans and transfer case all had fluids done)

Saw it this morning, sure enough, the bearing was toast. He told me he thought his tech was BS'ing him when he heard there was a Ranger with a knock. He said it is just bad luck, which is what I told him, I couldn't find a single other Ranger in the forums that had an engine replaced. Probably a covid engine since we purchased around March 2021.

He said the Turbo oil lines looked good which was another worry I had.

He also mentioned that at their dealer they have not had any Rangers come in for the CDF drum either. He said the Rangers are very reliable overall.

Really, there was no warning of this. Maybe the person doing the oil changes could have seen some metal or maybe the oil filter caught it all. Even if someone did see something, until it failed, Ford wouldn't have done anything anyway.

It will get a remanufactured long block which I get it. He did say that the rotating assembly is new in them. It could be a mix of what is used though but I would presume the block and head castings are what is rebuilt. Maybe I will get lucky and have a new block too but I wont care enough to check castings. I just want it working 100%. Looking at all the new trucks, I really just want my 2021 back. Sure a 6G Raptor would be cool but it is like Eh, awesome truck but I love my truck.

Just sharing should it help someone out.

I know we've been talking about this Anthony but it sounds like they're really taking good care of you. Still a weird thing to happen seeing you take such good care of it and do all the preventive maintenance on it. At least it didn't happen on your trip and you were close to home and have a stand up local dealer. It's also nice to hear their response about the time which is what it should've been. Good luck and hope you get back into your Ranger soon.

Oh...Stay away from the Raptor cuz you know it'll end up following you home! ?

Wow - sorry that happened! I wonder if ford will look to find the root cause as there is no way it’s maintenance related. Sounds like you got a great dealer as well. That just cemented me buying the Extended warranty if I’m not in a new truck in the next two years.

Sucks that it happened, glad they are taking care of you though.

One of my big worries with this vehicle, is something happening and the dealer I go to giving me a hard time. So far though, the 2 times I have been there for issues, I have been treated well. Working for a dealer I see how service can be sometimes lol.

Wait, what? I'm calling BS on this one.

Sorry to hear about the spun bearing.... I had a Ford 3.0L V6 in a Tarus replace at 26K once. Nice to see Ford taking care of you.

On a not really related example, per sa but speaking of "blown engine", here's a John Deer large corn combine with 340 hours on it...

Ouch!! $100K to replace. (warranty covered it)

PS: This happened during harvest season Oct. 2024. Happened on a Thursday; engine was out Saturday morning; new engine arrived on Monday; running Tuesday evening; back in the field harvesting Wednesday.... all work done in the field where it broke!

Must have been the full synthetic oil. Ford calls for Semi-synthetic Motorcraft. :)

Glad to hear Ford Country taking good care of you as I bought mine from them in August 2021.
Knock wood, fingers crossed no problems in 40,000+ miles.

It's nice they stripped the engine all the way down so you could see the failure (I assume this based on your photos). I've blown two engines (not Fords and over 100K) but other than getting a few metal fragments and some theories I've never had a mechanic take apart an engine. Nice they gave you a loaner vehicle too!

Sounds like you have a great relationship with your dealer.
Aside, what is the purpose of the large gear near the center of the crank?

My '19 Ranger was having transmission shifting issues, like many have. I had mine in the dealer and they diagnosed it as the main control panel and valves. Part was replaced and I am now approaching 1000 miles since repair and I can say the shifting issue is resolved. Point I am headed to is, my dealer also said that they are not seeing the Rangers with the cdf failure, very rare is what they told me, but it is mostly F150's with this problem.

As to the main purpose of this thread, that engine failure looks like it may have been a bad part to begin with. Yes, the 2.3l is a very reliable engine. My Ranger has 77k and our '21 Explorer Limited has around 58k miles and both are not having any mechanical issues. Fortunately the Explorer has the 10R60 transmission, as does the 6G Ranger, so no issues there either. :)

I agree, despite it's relatively high state of tune, the 2.3 appears to be a fairly stout engine. You don't hear of many failing mechanically. One reason I wish that Ford had offered it here as an option in the Ranger, instead of that crappy 2.0 L rubber belt driven diesel. But no, if you want a 2.3 you have to buy the Ranger VW clone, and Volkswagen have opted to put it in the post expensive model.
