Diesel purge, transmission svc, fuel filters, oil change, finger valves, vacuum line replacement, and CAI; done as the initial maintenance even when the PO did it previous to me buying it. Actually the body is going way before the engine, drivetrain, and suspension...
I cleaned the banjo bolt and line and that was not even dirty. The guy replaced the turbo with a reman fact unit. New IP, Chain, guides, new primer pump, fuel tank sending unit etc... Vacuum pump working.. transmission shifts clean...
The only thing I am leading to is the:
Valve adjustment
ALDA failure hence removal (more for performance)
stiffer boost actuator spring
exhaust system
custom cam grind
custom tubular turbo manifold and larger turbo
3" turbo back pipe
