View Poll Results: When I start the truck with the turbo on, will something blow?
If nothing is blown now, doesn't sound funny, and no shavings no you'll be fine
Very good chance or a positive chance something will blow when turbo is attached

Lets assume my motor was ran out of oil very briefly...

But when your done you know what you got. I saved a ton doing it myself to. Just an idea of what your looking at with a rebuild.
Dude, that truck sure is causing you a lot of of grief.
Running out of oil for less than 30 seconds probably did not ruin the engine. But, you may have metal shavings scatttered thru-out. If you're going to try and run it, at least wash out the intercooler and all of the piping before it sees any boost.
I read in one of your post, that you plan rebuilding the whole truck. I'm doing that to a 95 right now, and it looks like it's going to cost me about $12,000 with already having a good engine. And, I can do all my own engine, chassis, brake, electrical, welding, machining, painting, etc.... If you're going to try it, make sure it doesn't overwhelm you.
From the way it sounds, your current truck has been rode hard and put away wet waaaay too many times. If you could make the repairs yourself, you might be OK. But if you need to rely on shops for the work, then you better have some pretty deep pockets. I think your best possible solution is to sell or part out your current truck, and buy another one. There's plenty of the 12vs on ebay going for what you're likely to put in this one to halfway staighten out.
The turbo was fried the shaft split in half so the shop took it off and plugged the oil supp line and idled it for an hour. Says it ran great idled awesome no sounds etc. There is no chunks in the oil.
Yes the truck is causing me grief but hopefully once these issues are taken care of I can really dig into this thing and start rebuilding the truck. Thanks for the input so far tho guys
Alright quick report from the shop.
He said with the turbo off just idling, after the truck gets warm oil starts seeping out from the 3 rear cylinders into the exhaust manifold. He says it isn't terrible, and is driveable (he just doesnt know if he'd RELY on it), but the rear three are putting a bit of oil into the exhaust manifold.
Now the thing is, I'm not sure that it didn't already do that when I first bought the truck. I never ran the truck w/ the turbo off so I'm not sure that the oil in the exhaust manifold isn't something that was already there.
He says the pistons or rings might be scuffed up, but other than the small oil coming out its running great.
Has a new damper, new front cover, new seal, 16.5* timing, and soon to be a new turbo (hehe).
