i have a t3 turbo and it smokes alot and it has pretty bad shaft play. i was wondering with theses problems can i not be boosting anymore?? because my boost gauge isnt going up past zero and i think the turbine wheel is hitting the inside of the turbo?! (sorry im a newb into the the turbo world) i think the turbo crapped out after i kinda pushed it at 15psi. i was not paying attention to the gauge. so now when i try to boost it, it wont boost like as if its running n/a..... please any feedback is welcomed!!

like i said this is my first turbo setup!




please negative comments to yourself!

 

ok it was making 15 psi? and not now? do you hear the turbine hitting the housing? it can be pretty loud.

second, look for a boost leak. if there is a gross leak, there is nothing to regulate boost and you may have overspun the turbo.

 

blue smoke from ur exhaust at idle?

 

yah i got it up to 15 my friend in the passenger was watching the gauge i saw the gauge for a second it was at 5 the to 15 then stop.

i kinda hear a gross leak sounds like oil is squirting kinda sound and yah i hear the turbine hitting your housing its pretty loud!

 

there is alot of smoke but not to sure if its blue...

 

why not replace the turbo if you know it has bad shaft play anyway? seems silly to try to diagnose any further.

 

I vote replace turbo no need to trouble shoot more..

 

^^^^^alright guys thanks!! gonna look for another turbo
