Blown Turbo

[merqury]

I noticed a huge exhaust leak from between the headers and turbo. I thought the gasket was blown. I took it to my mechanic to replace the gasket. Turns out the turbo has seized; it wasnt spinning. As a result of that, the exhaust gases had nowhere to go and were coming out the top. I just towed the car back home and now I have the turbo sitting at home.

How can I tell if its seized? The compressor wheel is hard to turn. Is that the only sign? What if I loosen the compressor nut on the turbo?

What could be the cause for it seizing? Would it seize because I didnt let it cool down after a drive? My mechanic told me that there was no oil going in to the turbo, how can I verify that?


I just bought the Talon 6 weeks ago. Didnt drive it for even a day, just kep running into problems. More than $3500 put into it, and now this.

You can't take out the turbine wheel with no repercussions, but you CAN take off the turbine housing with no problems.

With the center section on it's side and the oil drain hole on the bottom, and looking directly at the turbine wheel, the turbine wheel rotates counter-clockwise. I don't know exactly what you'd be checking for, though. If it's difficult to turn one direction, it'll probably be just as difficult to turn the other direction.

Well the turbine spins much freely now, however it still gets stuck once in a while. When I took it out of the car it wasnt even spinning. What can I do to fix this? And do you have any tips for removing the turbine wheel?

I appreciate your help.

Yeah hard to turn will about do it. The nice thing is that Mitsubishi rebuild kits are plentiful,a nd the journal bearing design has such loose tolerances that you can rebuild it yourself if you desired. Good luck!

I took out the turbine from its housing, but I cant seen to locate the locating pin. I'm referring to the vfaq. Is there such a thing on the T25? Here's the vfaq image

Push the two ends together pop up the ring, and pull (or use a rubber mallet).

Gruppe, the OP has a blown T25 and is inquiring about that. He's just using the VFAQ picture as a reference for his questions on rebuilding the T25.

As for taking the turbine wheel off, that's going to be pretty hard, since the turbine wheel and the shaft are pretty much a one-piece affair. The compressor wheel might be able to be taken off, but after that, there's not going back without rebuilding and rebalancing the turbo.

Long story short: I still think it's a far better use of your time and money to upgrade and replace your turbo rather than rebuild your blown T25. But it's your car. Good luck.
