nope. im running stock pvc system. and catch can lines off the valve cover. could me not running water lock these fuckers up?

Re: another turbo got locked up
 

that depends on how many lbs your running....

Re: another turbo got locked up
 

its seen 20+psi

Re: another turbo got locked up
 

So you have air pressurizing the manifold and from the manifold back through a little hose into the stock pcv (blowing the check valve backwards), and then blowing into your crankcase?

Re: another turbo got locked up
 

sure?

Re: another turbo got locked up
 

People run themn just oil cooled all the time, but I don't think they're pushing them to 20+. I'd say it's unlikely, but it very well could be. You should take your blown one apart and see where the damage is. They come with 360 degree thrust bearings stock and have a pretty large cooling slit and oil passage to the thrust bearing, but maybe the added heat is causing problems. I have no facts and it's all speculation, but it could be. Are you using any sort of RTV or sealant on your feedline?

Re: another turbo got locked up
 

I took the hose that goes from the top of the pcv to the manifold and cut it. Put a bolt in that same hose on the manifold to plug it, and then put another hose on the pcv and pointed it at the ground. So now air can come out of the crankcase like its supposed to... You can do it other ways or use a catch can, whatever. But you should have that crankcase vented somehow. Cars used to just have a hose dangling down before emissions requirements forced them to vent the crank back into the intake to help burn off any extra fumes.

Double check you have oil coming out the return before you bolt everything up and post some pics of it or something

Re: another turbo got locked up
 

you should have zero kinks in your drain. none not even a lil bit.

Re: another turbo got locked up
 

would a slgiht kink lock turbo's up? im scared to put this new turbo on and it lock up aswell

Re: another turbo got locked up
 

If it can't drain and the oil sits there, it might coke on the bearing. Eventually coking on the bearing will cause it to sieze.
Straighten the drain, make sure it's clear...
