Bye bye turbo

[AdamHarris]

I mean just stop and think about it yall; You have a customer who has knoweth not how turbos are constructed (no offense intended to the OP), you have a "service advisor" who most likely knoweth not how ANY of it works and probably doesn't even talk to the actual Tech doing the work for fear of looking like an ignoramous. He is subject to telling the OP ANYTHING to just get him to leave!

The auto biz , it's a thing of enduring beauty, with varying degrees of ineptness and dishonesty, prime example cited on here is a dealership with apparently Ford's approval wanting to replace a torque converter when a $25 part was the real fix, more reasons some are embracing EVs, far less complexity and vastly more efficient than ICE. Looking under the hood of the Ranger it's a maze of hoses, sensors, tubes, pipes, reservoirs, heat exchangers, egr plumbing, wires and so on, somewhere buried in there is the actual engine. But hey the op appears to drive a Ranger with the chrome package so he's A ok in my book.

I found out by talking to the mechanic, they found a nut, the nut that mounts the turbo. He said when they replaced the turbo they probably dropped it in the airbox and instead of looking they probably got lazy and got another one. Anyway Here is a pic of the damage.

I’ll leave it at this ?

Have no idea what you are talking about. Literally created an account to see if this has happened to anyone lol.

Here’s a good cutaway of what the internal’s of our turbos look like. The nut for the cold wheel is on the left and the turbine shaft and wheel are one piece with the wheel part being on the left. There’s no bolt or cotter pin internally as you can see. Just a good visual reference

Thanks for that, I’m up to speed now.

Picture matches techs story exactly. Technically called foreign object damage. Crazy how something like a nut can be stuck in an intake track and dislodge so much later. But have seen it multiple times. Hopefully they went through the intake system and got everything out. I suspecting they did after their findings. Thanks for posting the pic, it answered many questions.

Ye they went through the whole system to ensure there wasn’t anything else.

The carnage of that scroll is intense.
I would love to see the size of the "object" that did this and it's ultimate condition in the end.
A small nut would have low enough mass to be lifted by airflow, but not enough mass to cause that, as it would likely pass between the vanes after a couple hits.
A large nut would be difficult to move with airflow initially, but if its like a square peg in a round hole, it could bounce around for some time. I would then be curious if this noise was audible in the cab.
I've sucked up a Lego in my vacuum. There's no mistaking the noise.

That wheel will rotate between 50,000 and 150,000 rpm. No such thing as passing between with just a couple of hits. Depending on what type of material the object is a pea sized object can do close to this type of damage. Seen it multiple times

 

[Floydean]

It was a nut, the tech couldn't find it when I was there. He’s gonna send a pic if he finds it.

 

[Sanctus Rimor]

I have heard of this. People somehow hacking your key fob.

Yeah, but in Alaska? I doubt anyone up there that would use tech like that for nefarious purposes would even know that tech exists. Same here. We're pretty darn similiar. HI is just AK without the snow. We're the red-headed step-children of the US. AK are the kids they keep in the attic. HI are the kids they keep under the stairs.

yeah with blades spinning at that speed one could readily see the nut hitting a blade, bouncing back, airstream sucking it back hitting another blade, a repetitive cycle until turbo is put down, stevedbvik1 knows turbos, I've only rebuilt a half doz of them, a video of me in action

That came apart real easy! That’s usually not the norm. Especially with the Garrett’s bolt on turbine housing. Usually a broken bolt or two and a heat and beat session ?

video posted before and in humor - the guy says make sure you use left handed pliers to remove a left threaded nut, it's obviously a staged video as you'd never be able to disassemble a turbo with the tools shown. I rebuilt a few garretts but yrs back, weren't really bad but glad to see Ford uses borg warner. Garrett declared bankruptcy and was acquired by a private equity firm (KPS) , I had honeywell stock and when garrett was spun off had some shares of garrett which proved to be worthless.
