Re: water line broke off turbo
Yep, think about what's happening inside the turbo when it heats up.....
The center section is cast steel, so when that heats up all the tolerances inside increase, so your bearings aren't fitting as tight as they should, this will allow the shaft to deflect more and possibly let the compressor rub against the housing. You won't feel any of that driving, but as it happens more and more your turbo will loose efficiency from the compressor and the housing being rubbed. You'll even see this on good running turbos properly hooked up, now take away the cooling, and do enough hard pulls and you're taking a toll on the turbo.
I'd start making plans for a turbo swap if you're gonna leave it like that for any period of time. Start scouring the classified for a good used turbo, or maybe the scrap yards, recondition it before hand and then pick a day where you do the swap,
