Inspection (All Models)
- Check for loose duct connections from air cleaner to turbo assembly, cross-over duct to intake system. Check turbo wheels for impact damage from foreign objects and wheel contact against housing walls.
- Check shaft for free rotation. Push inward on one of the shaft wheels while turning it by hand and feel for any rubbing or binding. Do the same on the other side. Wheels should turn freely without contacting hosing, backplate or shroud.
- Check oil drain line for restriction. Any restriction can cause severe oil loss through the turbo seals. Check for traces of burned oil on turbine housing exterior. Check oil supply line for restrictions. Restricted oil flow will cause severe damage to turbocharger.
