I've got a new turbo on the way. I'm going to feed it from the ofh with a new supply line and hope that solves the problem. Maybe I messed the other one up when I rebuilt it.

oh really?! It's a catless 3" turbo back exhaust. Plus an extra leak in the flex pipe for good measure. This seemed weird to me but I was gonna chalk it up to my old braided stainless supply line being partially collapsed or something.A bent shaft would have uneven wear on the thrust surfaces...

welp.... looks like the turbo saw prettttty much no oil pressure. Guess I'll be getting a whole new turbo and not reusing my current oil feed or drain because clearly there was an issue.Still weird how much wear is on the thrust bearing but there's very little wear on the journals.

Thanks everyone for the feedback. I think I'll have time to tear it apart tomorrow finally and see what kind of wear is on the insides. I don't think there has been any contact with the housing at this point so maybe I'll try a rebuild and feeding it from the OFH instead this time.

Ya I used an OEM rebuild kit from the guy who made the billet wheel for me. It's just strange that there's very little side to side play so I was thinking mayyyybeee a bent shaft causing the thrust washer to wiggle while spinning? I haven't gotten it apart yet but I don't want to rebuild it if...

I recently installed a billet wheel and matched/ balanced turbine in my 16g turbo with a full rebuild kit. I ran it for a few hundred kilometers at 20 psi. It has developed a lot of lateral play but hardly any axial. I am running a 4an braided line from head and running stock return line. Im...

probably not your issue but your TPS is out of adjustment. use the TPSadjust tool in link get it in range

Boost leak test?Edit: Sorry missed that!

Hopefully you just dropped the spark plug, but if not you've got some mechanical issues :(

So I think I've figured out the issue. Checked my turbo and it has a ton of slop. Ordered a rebuild kit so I guess I'll be out of commission until that arrives. Hopefully that will solve the smoke issue.

any thoughts as to why it keeps going rich as soon as I let off the gas? I have my BOV before the maf.EDIT - I see that my throttle position never drops below 1%. Maybe that has something to do with it. Tomorrow I'll readjust the TPS and see if she's still blowing smoke. The only thing is that...

It was the Wideband!!Working a lot better now. Still blowing huge clouds of grey smoke after coming to a stop. I even got into a tiny bit of boost tonight and besides the phantom knock from my exhaust hitting the frame it worked quite well.I'm gonna try and fix the exhaust issue tomorrow so...

The honey comb is there to straighten and even out the air flow across the full area of the MAF. It would definitely throw your readings off, but at any rate why not just take a trip to the junkyard and find a new GM MAF. They are really easy to get a hold of.

I dug out my old NGK AFX Powerdex Wideband kit.Gonna try to get it wired into the car tomorrow and we'll see what happens.Thanks again for the help my man!

shit fuel - 91 octane. It's all I can get.Got the pressure set to 40psi, but also have Link set to 40psi.
