well i went and removed my turbo and manifold and when i pulled the turbo off i almost cryed..there are 2 fins that are almost complately gone and a couple that are chipped, im figureing one of 2 things could have happend

1) my car throw a apex seal (but i belive i hear the right amount of "swosshes" when i crannk the car by hand)

2) a big nasty hunk of carbon came loose ( the car has sat for about 14 months)

if it is a seal im not sure what im gonna do i dont have the money to get it rebiuld i might do it myself, but how are would it be??

Does your car burn any oil? It could have been a side or a corner seal. Is it the hot side that you saw the chips? If it is, something got chewed up... most likely a seal of some sort. do a compression test.

A big hunk of carbon? Well it doesnt really take much for something to bust when something's spinning at 100,000RPM +

 

my car really hasnt run for about 4 months but it did not burn any oil, but im gonna do a comperssion test today so i will see............... any one else??

So the car will not start, or you haven't tried to start it in 4 months?

I'm betting all my peanuts on a chewed apex/corner/side seal.

 

...ever cleaned up the castings, like the manifolds, ports and whatnot?? if not, coulda been a bit of casting flash. *shrug*

 

my car tossed an apex seal, I only had a tiny chip in my turbo. I could probably even still use it, but I decided to err on the side of safety and buy a new one instead.

for big chunks to be missing, something major would have to happen, I'd think.

 

his car starts, just doesnt hold and idle but we think thats due to a vac leak. I saw the pictures of the turbo, the hot side is destoryed

 

Mine ate 3 seals and my turbo is fine. It boosts great. The only problem is the oil seals leak a bit of oil (stops once the turbo warms up).

 

This same thing happened to my turbo but it was not a problem with the engine at all. Im giving hope to your engine and pointing the shame to a common problem with s4 turbine housings.

My first turbo blew when the turbine manifold cracked sooo badly that a large piece chunked off and slammed the turbine wheel. So check your turbine housing for any pieces missing. You'll have to pull the cartridge off the housing.

What my turbine looked like. notice the blue shaft.

 

How did you make out with the turbo??
