tooquicktostop Posted January 2, 2009 Share Posted January 2, 2009 Took the Supra to mates house yesterday, 70 mile trip, took the GF so no on boost driving really, left their house and made my way down the M1 back to London when I heard a metallic noise from the turbo, on boost it sounded like a band saw cutting through metal, then all boost lost and no noise from turbo, no smoke not drama just lost the turbo, AFR's were fine so limped towards home, 10 mile to go turbo wakes up again and same metallic noise, boosting as it should however Got home and removed the filter, the blades look fine but the shaft does move left and right, can I really have lost the turbo, its only 2000 miles old and has not seen boost very often I was not on boost when the noise started !!

Nic Posted January 2, 2009 Share Posted January 2, 2009 Where is the EGT sensor located? Just a suggestion, it could have been that which went through the exhaust side. Quote Link to comment Share on other sites More sharing options...

It looks like it is at the very top of the down pipe to me, Ex temp gauge was working fine throughout Quote Link to comment Share on other sites More sharing options...

jevansio Posted January 2, 2009 Share Posted January 2, 2009 Its spinning ok by hand, just sounds noisy, would a video clip help ? My DBB spins for ages after I turn the car off, a spin by hand could go for nearly 10 secs. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted January 2, 2009 Share Posted January 2, 2009 Have to say it sounds like the bearings are worn/loose enough to allow the turbine to jam against the housing, from time to time. Quote Link to comment Share on other sites More sharing options...

JDModified Posted January 2, 2009 Share Posted January 2, 2009 Remove the compressor housing and check it on the inside for scoring/marks. Its a 10 minute job. James Quote Link to comment Share on other sites More sharing options...

Axle Posted January 2, 2009 Share Posted January 2, 2009 After 2000 miles or so, what a nightmare ! Real gutter if this is the case. What make is your T67DBB? Is there a pattern building with these DBB's? I am reading conflciting opinions on their reliability. But after 2000 Miles? Has somthing accelerated (pardon pun) its demise? Assuming the Turbo has gone to pot. Quote Link to comment Share on other sites More sharing options...
jevansio Posted January 2, 2009 Share Posted January 2, 2009 dean its dead simple i did mine myself:d 5 bolts i think at the back of the cold side 6 bolts, they work in pairs, each pair holding a small tab which holds the housing in place Quote Link to comment Share on other sites More sharing options...

Jazzy Posted January 2, 2009 Share Posted January 2, 2009 Could it be worth checking the water feeds aren't blocked and caused the bearings to overheat? Quote Link to comment Share on other sites More sharing options...

supradibbs Posted January 2, 2009 Share Posted January 2, 2009 Bearing sound shot mate Maybe overheated and siezed and then all cool maybe released Quote Link to comment Share on other sites More sharing options...
Steve Posted January 2, 2009 Share Posted January 2, 2009 Oil starvation to the turbo causing the bearings to fail? Maybe check there is oil getting there. Quote Link to comment Share on other sites More sharing options...
JDModified Posted January 2, 2009 Share Posted January 2, 2009 Doh that doesnt sound clever mate, a detailed look at the oil supply and return on that turbo to find out what happened. Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted January 2, 2009 Author Share Posted January 2, 2009 Can it be rebuilt or is it best to replace Quote Link to comment Share on other sites More sharing options...
JDModified Posted January 2, 2009 Share Posted January 2, 2009 No doubt a rebuild can be done. If it has a t4 footprint I have a used Turbonetics T66 hybrid that can be used intermediately. James Quote Link to comment Share on other sites More sharing options...
