VNT Turbo Repair

VNT Turbo Repair

2 turbos came in today, both had failed on a Hino J08E 500 Series Truck.

Upon inspection it became obvious that the turbocharger had been repaired (which had been carried out as an unauthorised repair of a Garrett VNT Turbocharger using non-genuine  components);We do not repair VNT turbochargers in our workshop, Garrett Turbo have a strict non repair policy on all of their VNT turbos and as a distributor of their turbos we are not authorised to repair.

Genuine replacement parts for Garrett VNT turbochargers are not available and therefore a GENUINE authorised repair can not be carried out.

These pics show the cause of failure
