Okay. Long story here, but I hope at the end of the post my issue is clear enough that someone can help me at least figure out some diagnostic tactics to find out the cause.
2016 Expedition Limited with the 3.5l EcoBoost
December-ish I was driving home, normal highway speeds, no excessive acceleration to speak of. I come to my exit, stop the vehicle, go to drive again and she feels sluggish. Gave the gas pedal a goose to see if there were any strange noises under load, and I heard the turbo spool, rattle, and then a clunk/whistle.
Great. Dead spooly boi.
We take the truck to a shop my father in law trusts. Ready to replace both turbos. My logic being, both turbos have been on the vehicle the same amount of time, under the same stresses, if one went I can expect the second to go shortly thereafter.
Shop only replaces one. with either a reman or aftermarket. I could not get a straight answer since my father in law was the middle man, and he only kinda knows things about cars, let alone turbos. They claim the other is fine, they "took it apart and it looked fine so they put it back in". Gotcha.
Either way, we have it back less than a month, and same thing happens. This time my OBDII reader won't even read that there's a turbo on the vehicle, let alone show me boost.
Same Turbo. Covered under warranty. They replace it yet again.
Wife and Father in Law go to pick up the truck. Get less than 5 miles from the shop, whole dash lights up and the truck goes into limp mode.
Back to the shop it goes.
Shop claims it's the timing chain.
Father in law gives the go-ahead without my say-so. whatever.
Few weeks go by. No news. Earlier this week, get a call, Truck is ready, wasn't the timing chain, was the turbo again. Fixed, ready to roll.
I find out they took the turbo back to O'Reiley's, got the "next model up", put it in, blew that turbo within a 5 mile test drive. Took THAT one back for the "next model up". Another kaboom.
Went to Ford, got an OEM turbo. Put it in. No kaboom. (yet)
Also there was fiberglass trailing out of my exhaust, they tried to tell me that the previous turbos were made of fiberglass and that's what was coming out. (Bull... muffler packing, anyone????) So they cut off my back muffler and straight piped it. Whatever.
I pick the truck up. Get it home no issues. Having a happy day.
I go to drive 'er again, start noticing a scrape-click type sound when the turbo would engage. Also that distinct lack of oomph (my '07 edge would beat it in a drag race right now) that tells me, once again, there's an issue with the turbo. It's also making some fun whistling sounds, sometimes under load, sometimes when I'd expect to hear a BOV.
At this point SOMETHING in my engine is blowing these turbos. There's not a chance in hell I got this many bad turbos one right after the other.
Anyone have any ideas what could be causing this? bad manifold, maybe?
Any help diagnosing this would be amazing, I am personally overseeing all of this from here on out so there's no information getting mangled by people who don't really know vehicles very well.
I plan on getting under it in the next day or two and checking the wastegate and the BOV to make sure nothing is wrong. I'll be connecting my OBDII reader up to see if it'll even show that there's a turbo on the vehicle.
At this point I'm a little over 2.5 grand into this, still at square one, and ticked off.
Thanks in advance, y'all.
