I have recently rebuilt my turbo, replaced HPOP lines and a few other things. Truck has been running well. It blew out the HPOP line, prompting this work. I got home tonight and noticed that there was oil spots on the fender of my trailer on the exhaust side. Upon further inspection, the tail pipe appeared to have oil around it and the inside appears wet.

What do I need to be looking at? I still have the crankcase vent hooked into the intake tube. I don't know what could be wrong on the turbo. There is only this small snap ring style seals on the turbo shaft. Is this something that can happen until thing seat in good? I rebuilt the IPR and deleted the EBPV system as well.

Could this be something left over from the. HPOP busting?

Take your down pipe loose and look at the turbo outlet for signs of oil. If it is in fact leaking, something may have gone wrong with the turbo rebuild.

 

Checked the exhaust pipe at turbo this morning. It was wet with oil. I pulled the inlet tube off to check play and there was 3/16 or so play. I felt like this was too much. Pulled the turbo and there was definitely too much play.
I don't see anything that looks out of whack but I would like to see a diagram of the order in which all the bearings and spacers go on the shaft to ensure I have everything positioned properly. Anyone know where I can get this?

Does anyone know what the inner and outer diameter of the brass bearings should be?

Does anyone know if the piece that fits between the shaft and the compressor plate that the seal snaps on to should be a tight fit or loose fit into the compressor plate?

Contact Barder Turbo...he'll help you out.

 

I never did rebuild mine when it went so I can't answer. Here is a bump for you anyway. Someone smarter than me will be along soon.

 

I did. He is sending me two new brass bearings and new snap seals. Thanks.

I feel like the play is in those bearings. Would spinning the turbo up to quickly before everything is broken in cause this? If so, what kind of break in period is suggested after rebuilds?

Ryan

 

There is no breakin period. Just be sure to prelube the bearings prior to installation.
When mine failed, I upgraded to a 38r.

 

Hmmmm. That concerns me when I can't find something definitely wrong. Hopefully it will go back together.
