Play should be measured on the turbine side, not the compressor side.

Also, feel around the turbo to manifold and turbo to downpipe connections and see if you pick up alot of soot. If you do, start the car and listen for an exhaust leak.

If the wheels were hitting the housing you would know immediately, it makes a very distinct sound that does not sound like turbo whirr, it's a very fast knocking noise.

You typically would not see any metallic flakes if the wheel was hitting the housing as these would be immediately sucked into your engine. You can pull the angled coupler between the charge pipe and turbo and generally the oil film will have collected some of the aluminum debris.

yeah, the turbo is shot... took off the AFM and put a mirror up there, the compressor blades are all bent and missing corners and stuff... and I did find metalic flakes in the intercooler pipes...

Geoff, Dude! What the F happened? You are soooo on the mod path now.

Mike, there is so much runout on that you can see it from across the street!!! It's pathetic. And this "repair" has zero hours on it!

If you need a replacement I think Travis (Porschefile) would slang you his turbo. Get you back on the road at least.

Hopefully there is no engine damage.

Mighty Shilling

there doesn't seem to be engine damage, it's not as bad as it could have been... but I'm still going to clean up everything that gets air after the turbo... I'll be doing that when it's all apart...

i hear the 276 spooling below 3k.

I hear mine spool until it starts making a few psi, at that point exhaust noise takes over

Geoff, are you doing some sort of an investigation as to the cause of bent compressor blades?

Hope all is well inside!!

And now I'm worried... I can here my turbo too

Mighty Shilling

I'll check it out when I pull the turbo off. I saw through the mirror that the compressor nut was still there, so that isn't the cause. if I had to guess, the bearing went out, had some wobble to the compressor wheel. with the compressor wheel's new found freedom to move around, it decided it would declare war on the housing and attack it... well, it lost...

Geoff, that sucks man! I know the feeling.. Sounds like its time for a K27/6 -- if you can wait for a little bit you might find one for $600 or so. Or you can go with a K27/8..

Mighty Shilling

I've got a K26/8 coming in from Paragon, should be here friday. as for the old one, I've got someone who's offered to buy the /8 hotside, but if that falls through, I might be able to make it into a K27/8... hmmmmmmmm....
