I looked at the turbo's today, both of them have enough shaft play that the blades are hitting the compressor housing. WTF happened? Did I get a sh$t pair of turbo's or what?

Sounds normal to me, OEM K04's have a lot of shaft play.

here is a video of the shaft play.<ul><li><a href="http://videos.streetfire.net/video/a44c5cd8-74cd-42d4-9e48-989e011e0416.htm">http://videos.streetfire.net/video/a44c5cd8-74cd-42d4-9e48-989e011e0416.htm</a</li></ul>

enough shaft play to hit the housing.

Why did you have your turbo's removed?

elijahallen

Because the car is smoking on decel and I can't find anything or anyone who knows what it could be caused by and I just assume its the turbo's since I have had turbo's go like this before. Compression is good, the engine has 64K on it. We added a catch can to the pcv system and it stayed the same or got worse. It only smokes on decel, not on startup (meaning valve guide seals are unlikely), like I said, 64K miles so I sure hope piston rings last longer than that, not sure on head gasket but haven't heard of them haveing this problem in the past.

if your blades were making contact with the housing you would know, it would be very obvious once the turbo's were off, and on accel it would be pretty bad.

Possibly running to rich? Do you have any EcuX logs of your car, fueling, etc before you had your turbos removed?

elijahallen

running rich would mean flames and black smoke not grey blue clouds like I have.

Killer00S4

did you see where the blades made contact? Is there wear on the blades, etc? If not then most likely the turbos are good and something else is the issue.

What software kit do you have?

elijahallen

fine. I'm running Vast stage 3 tuned by Mike himself.
