GREAT news (sarcasm)

So finally got my truck painted and back together and fired up for the first time in almost a year and a half. Turbo was smoking like a SOB and leaking oil like a siv. Oil pressure was a little high according to the stock guage but nothing crazy. First suspected the drain line since it is still stock and turbo is aftermarket PTE52. Checked it and it's good to go. So took the filter off the compressor housing and checked the shaft (let the jokes commence lol) and WHOA there was probably at least 1/8" of play up and down. So bushings and seals are shot!! Awesome.

I was lucky though...took the turbo off and inspected the fins (both compressor and exhaust) and they're good to go :tup: And luckily there's a very reputable turbo shop local that should be able to rebuild it. I get to call them tomorrow and find out.

At least I am experiencing the "SyTy phenomenon" lol...I've had the truck for 2 years and have driven it for a month :rant::rant:

Yep, totally normal stuff for a SyTy.

It'll have SOME play, like a few thousandths. 1/8 is waaay too much.

I'm under the impression that a sleeve bearing turbo MAY have lateral play in the shaft,while checking it 'statically', because there is no oil pressure to center the bearing. If the compressor and turbine wheels aren't rubbing in the housings, it's OK.

Am I wrong? An 1/8 inch doesn't seem like much, in light of the above.
Fore and aft play is not good. Not to be confused with foreplay.

After I got it off and inspected there is NO evidence of it rubbing on either housing which surprised me given the amount of lateral play in the shaft. I did not check fore and aft play as I was really pissed off last night considering what I found. I'm going to talk to the turbo shop today so we'll see what they say...

Changing the bushings is relatively easy. In my DSM days I re-bushinged a 20G using an old stock 14B dsm turbo's parts myself and it ran fine for 2+ years til I went to larger turbo, however YMMV. A complete VSR balance is the way to for true longevity.
