cracks in exhaust turbine housing,
Turbo Mini Forums

just removed my exhaust elbow, then waste gate part, only to find atleast 2 long cracks on the tubing exhaust housing. one crack runs from the waste gate hole, round into the exhaust turbine itself. the other runs from the waste gate hole too. i swear if i look into the hole the crack runs on towards the big rectangle mounting flange.















can any one give some good advice, ive got another turbo with a good housing, but that one has snaped studs in it etc,

As long as there not really bad should be ok, all the turbos I have used t2 and t3 have had cracks. I had one that did cause boost spiking but that was majorly cracked! Try it and see if it causes a problem repair your other one and use that.

ive used it b4 untill recently. running around the 15psi mark and i had no problems with it, its generaly in good nick. and the cracks anrt 'wide' so ill go with it, knowing that it works ok.

not entirely related, but my audi dailly uses a KKK borg warner turbo, and I've NEVER seen one that's not got cracks in the exhaust housing.....

most cause lttle issue at all, although you have to use a bit of common sense if they're HUGE cracks....

when i used to remanufacture turbos 90% of the turbos that came in had some sort of crack, some were bad and had to be scrapped but usualy would be fine

Pictures would help. But I've never seen a T2 without crackd around the wastegate.

ive taken my turbo to pieces thismorning, had to give it a beating, and cook it with a heat gun. ive striped my spare turbo, as the housing was good on that.

ive posted some pictures at the top of this thread :)
