Carl Posted July 25, 2010 Share Posted July 25, 2010 I have a crack in my turbo-wastegate housing. Can these be repaired and what are the implications, eg, does it all need re-balancing once turbines are removed from body etc. also what problems if I just install with crack?

Homer Posted July 25, 2010 Share Posted July 25, 2010 It's getting pretty common these days. It's not fixable, new turbo is required. Bad luck Quote Link to comment Share on other sites More sharing options...
bondango Posted July 25, 2010 Share Posted July 25, 2010 Very Common, and not just on ct turbos But, TBH that certainly isnt the worst i have seen, but its the seating area behind the wastegate flap which causes the major issues if cracked badly (cant be seen from your pic) Quote Link to comment Share on other sites More sharing options...

Swampy442 Posted July 25, 2010 Share Posted July 25, 2010 Yeah its fairly common. If the turbo is fine you can just replace the housing Quote Link to comment Share on other sites More sharing options...

Homer Posted July 25, 2010 Share Posted July 25, 2010 Yeah its fairly common. If the turbo is fine you can just replace the housing Or in Carls case the wastegate flange too. that sounds a bit cheaper! You ever tried to buy a housing for one of these? It's not like you can buy them off the shelf. As Marty says it doesn't appear too severe from the pics, but isn't the sort of thing that gets better over time.

Nic Posted July 26, 2010 Share Posted July 26, 2010 Very common fault, the cracked housing won't effect function/performance (half the TT's driving around probably have similar cracks). The cracked gate I would try to get replaced. Quote Link to comment Share on other sites More sharing options...

The cracked gate I would try to get replaced. Can you replace just the gate bit? I assume you mean the flap itself? I was speaking to CR Turbos on this earlier and as you said, they reckon 95% of Supra's will have the same crack. Its a common fault from the continual heating up & cooling down. Its always on the Primary No 1 turbo and nearly always in the same position. He reckons more often than not it only goes 1-2mm dp so should not cause a problem. If welded up he reckons the same thing would most likely occur within 5000 miles. Quote Link to comment Share on other sites More sharing options...
Nic Posted July 26, 2010 Share Posted July 26, 2010 Can you replace just the gate bit? Not sure, best to talk to a turbo specialist. I assume you mean the flap itself? Yes Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 26, 2010 Share Posted July 26, 2010 They can be welded up and machined (milled) back to size and profile, but they'll probably crack again sooner rather than later. I have 9 or more turbos here, all cracked. If you can still find any new stock left at Toyota that's by far the best route. Quote Link to comment Share on other sites More sharing options...
