I am looking at rebuilding/repairing the turbo on my albatross of a car. I would like any info about sources for rebuild/repair kits and any technical advice, hints, lessons learned, etc. It is an auto tranny, by the way. It is spitting oil into the exhaust system, hence plumes of funny smelling smoke, especially at rpm wind down and idle. It passed a compression test at the dealership, and all other aspects seem normal...Help!
