Turbo locked up tight

[samhain]

Hello,
I'm a newbie to the DSM scene My son and I just bought a 90 GSX with the motor not running and 106,000 miles on it. We pulled it apart and it was the typical bent intake valves so a head is on the way. I decided to look at the turbo while we are waiting and it is locked up tight I have a rebuild kit on the way too now. Just wondering if there is anything I should check turbo wise, is it getting oil? It is the TD05H should I check any of the other components? I will do a boost leak test for sure when its together.
Thanks

if its locked up i would do a rebuild on it because there is nothing worse than no power gain from a turbo and how do you mean locked up ??????

like froze and it wont spin at all????????

i would still do a rebuild on the turbo though

 

[samhain]

yes it wont spin at all I havent disassembled it yet and a rebuild kit is on the way. I have read the part 1 and part 2 rebuild in the tech articles very nice tut. I am new to turbos and just wondering if there is anything else to look for when they lock up.

there is the oil line holes i would check and coolant all of that good stuff but i was just throwing that out there

Make sure all the oil feed lines are clear. If it locked up, it was probably due to a lack of oil. If the PO didn't let the car cool down, then the turbo could have backed the oil into the internal oil passages, eventually blocking them over time. You'll be able to see that if you do a rebuild.

Sounds to me like this turbo was a victim of lack of oil, or oil coking around the turbine seal (causing the seal to bind the shaft) due to improper cooldown.

I've also seen instances where the turbine housing cracking on a 14B has deformed the housing in such a way that the turbine wheel makes contact with the housing- although I've never seen this totally stop the wheel.

You can't tell until you get it torn down.

DAMN son thats crazy

 

[samhain]

not quite that bad. I went ahead and tore it apart and it does look like the oil passages probably were blocked but I'm not finding any cracks. The seal is cooked but I think the unit is going to be salvagable. Thanks for the explanation about cool down thats what I'm going with then. I will assume I am getting oil from the motor ok.

yea i check for shaft play and was like its all good then finally after we couldn't figure it out we took it off and yea..... but i hope you get yours up and running again

What caused the turbine shaft to break?

What caused the turbine shaft to break?

heck if i know, i was driving home one day when it happened but it didn't make a noise or smoke or nothing. It just gave out i guess? i checked my oil line and all that but i still don't know what caused it?
