Psydriver Posted May 22, 2014 Share Posted May 22, 2014 I just bought my 2005 LGT with a blown turbo. I rebuilt the turbo and it ran great and really smooth for a couple of days. Today I finally got to take it out on a longer road drive and it started loosing rpm when it would shift until the turbo kicked in. By the time I got to my destination there was a knocking noise. Sounds like a rod but no metal in oil or smoking. I'm just curious to see if anyone else has had this happen or where I should began looking? car has 200k miles and supposedly new timing belts. Any insight would be helpful. Link to comment Share on other sites More sharing options...
RallyMachine Posted May 22, 2014 Share Posted May 22, 2014 VF series turbos cannot be properly rebuilt unless the center rotating housing is balanced too. Sounds like the turbo may have blown and sent metal through the engine. Link to comment Share on other sites More sharing options...
