Turbo issues..

Unread postby Corsa180T » Wed Dec 28, 2016 3:11 pm

Hi, was going through my turbo today and stumbled upon this (see pic). The heat shield interfaces with the center section becouse of a "lip" around the hole and I can't see other housings having that. Or I'm I missing something?ImageImage

This is what I have, the turbo came in parts when I bought my Corsa.

That is the turbine side of the bearing housing. The only item on that side would be the piston ring. That looks like someone pushed a flanged bushing into it. Will it pry out? These are some of the bearing housings I have. Note no flange around that opening.
I should warn you that if you do rebuild the turbo that you should pressure test it as those bearing housings do wear out. The 2 shown in the picture are bad ones that had leakage problems.

Hi, I find a housing that has the same flange on californiacorvair.com but it´s not axactley the same model. I have tried to pry it out but it seems to be forged together.. I think I will try to find i new one but I have just find used ones. http://californiacorvairparts.com/2471- ... using.html

That housing is a later Rajay housing. It has some parts that interchange but is not an exact replacement for an original 62-66 Corvair housing. You can see it uses counter sunk style screws to hold the compressor housing on. You might want to try asking Ken Hand or Steve Goodman over on the other message board what that raised piece is for.

The housing in your first picture has either been welded or had a sleeve pressed into it, to correct an oil leakage problem resulting from the turbine oil seal being jammed into the housing and gouging it. You should use a later Rajay 310 series heat shield with it since it has the correct size hole to go around the ledge, or you can simply bust out the die grinder on your cast iron Corvair one to make it clear. I have the newer style shield in stock if you'd like to buy one from me.

I was thinking the same way before I saw that the housing was cracked on the other side were the snap ring will sit. So it will go into the garbage bag..Image

Could still be welded, but there are better housings out there...
