Is there is rub marks on the edges of the blading. If so, the bearings failed.
That is exactly what happened. Comp can stuff the "it ate something" BS. The inside of the filter and turbo where squeaky clean and you could clearly see the fins on the intake side had touched the housing. There was also a slight amount of play on both sides.

It was most definitely was a bearing failure. Someone somewhere is trying to hide what happened.

Assumptions without facts is always a bad idea.

Like I said before, there was an incident where the compressor cover was removed from the turbo at time of install, and not installed back properly (square). The damage was identical to this, and forum warriors were all over it...*Sh!t turbo, "turbo needs oil brooo"...bla, bla...BLA!

No different than 3 customers having overboost issues...forum experts jump right on that too, and say poor design of kit, this that and a bunch of other BS. Only to find out that the installer mixed up the vacuum lines.

Always enjoy opinions, base on 3% of knowledge about the actual situation. Been doing this for a long time, seen it all.

As for "play", every turbo has "play", especially a JB turbo. If it didn't, it would explode the first time it gets up to the 1,400 deg F operating mark under full load.

The fact is nothing went through this turbo. You and comp are assuming that happened.

And yes. Turbos need oil. Another thing they need is coolant. The first one is why your kit didn't make my short list. The second is some kind of bad joke

And how many of those janky air cooled turbos did you have drop shipped without changing your product description? I'm sure BettyZ wasn't the only person to open the box and go

"wtf is this? I didn't buy this"

"they cool the hot bearing housing with hot air and it's not even hooked to the oiling system to help cool it off"

No wonder the warranty is crap.

Sasha I know eventually these turbo were going to come back to haunt you.

I mentioned many types of higher quality turbos like the borg wargner efr9180, garett g35-950. The oil less turbo method limits the customer's choices.

I'm not sure how it works in Canada, but in all 50 States, offering a customer a product, and then delivering something significantly different, not only voids the contract but is also illegal. The technical term would be "fraud."

May not apply in my case as I learned this before delivery and accepted the delivery. But for those that had no idea, and thought they were getting a water-cooled turbo, there may be a cause of action there.

The air cooled turbo is a $200 upgrade...so customers were getting an upgrade at no extra charge...but okay....The itemized list was also updated a long time ago, and specifies "air cooled". There may have been a handful of customers where these upgraded turbos were shipped to, who may have seen the "water cooled" turbo on the part list.

How much cheaper is one that gets both oil and coolant? The downgrade to air cooled cost more than 2 lines and a couple fittings. If you downgraded to one that was properly lubricated does it cover the cost of a scavenge pump?

So, with thousands of these turbos out there on so many different builds, you don't think it would be easy to find issues with this line of turbos?

Water cooled with lines is cheaper than air cooled, and air cooled is more reliable than a complete scavenge pump setup.
