I had the same problem oil from comp housing,CR Turbos recond my T34 for £276 inc vat but i did give them a standard T3 2wd aswell

Took three days they collected and delivered

Price for a recon from them is about £330 inc vat i think

Mine was a stg 2 turbo

This i think is good value when burtons wanted £850 exchange!!!!!!!!!

Speak to Darryl he was very good
