Just picked up a 1997 GMC Z71 with a 6.5. New to the world of medium diesels (last was a 2003 Jetta TDI) and still very green on diesel to begin with. Truck has 189k miles and runs alright. Have some odd flutters and intermittnet issues to figure out. Vac line broken from pump, waste gate actuator removed and has a spring with 2 washers to hold open (showing no boost on gauge.) Pickup for boost gauge pressed into rubber hose from turbo to upper manifold. PMD was relocated to a heatsink but is just laid in the inner fender well in the engine bay, not sure of the brand. Thinking this could be the issue...Also has a leak at the filler neck...will be looking for some parts soon to get it right!



Think I did alright for $4k

Supposedly has upgraded injectors and new transmission but nothing to prove when or what. PO said it was done by the owner he purchased from a year ago.

Things to do so far:

Wastegate Acutator
Replace line from Vac pump
Clean VSS
Turbo to intake hose
New filters
Replace/Clean CDR (looks original)
Possible PMD
Flush brake fluid
Replace M/C grommets
Replace/rewire stereo
Tires
Bulbs in dash (no SES light, glowplug light, etc)
