My turbo started making much louder noises not unlike a dentist drill, after I reconnected the intake hose. I had it off to search for a coolant leak. The boot was torn so I tried to bandaid it with a piece on tire inner tube. I suspect a chuck of rotten hose was ingested and chewed up intake turbine blades. Has anyone used a rebuilder they would recommend? perhaps someone capable of upgrading better than stock.
