"New" Z on the way... 1991 #302 - ZR-1 Net Registry Forums

VetteMed · 04-15-2010

SO, the car arrived on Monday.

The problem list so far:

Oil leak from rear diff, may be pinion seal, as entire pinion area is caked with grease.
Leaking differential oil burning off from rear exhaust
Oil leak from front of engine - can't determine source yet, passenger side framerail caked with grease and dirt, oil cooler lines suspected, can't yet rule out other sources.
Wheel bearings are probably shot - whine/howl noise while driving.
Clicking sound from rear driver's side, upon initial acceleration - suspect U-joints gone bad.
Parking brake doesn't hold
Parking brake switch inoperative - light stays on
Bose is inoperative
Wear on seat bolsters
Cowl drains and hood hinge drains clogged with debris, preventing drainage (fixed )
Paint has dark staining, vertical streaking (fixed - orbital buffer and polishing compound)
Many paint chips, especially trailing edges of doors (temp fix with touch-up paint, full paint job in the future)
Weatherstrip is in need of replacement - hatch completely shot, others marginal but will replace.
Windshield delamination, not terrible, but there's a 1/2 inch stone chip blemish on the passenger side. I suspect I'll probably replace with a regular windshield.
Dirty interior - dust, bits of grass
Rear cross-drilled brake rotor cracked around cross-drilled hole
Headlight motors need bushings

The good:

The motor runs well, didn't really open it up fully because I haven't sorted out the driveline yet. Runs smoothly, good oil pressure.
Everything is complete - nothing hacked up or missing. Original owner sent me the pizza box, all service records dating back to 1990, service manuals, receipts for any aftermarket parts (Baer rotors, upgraded Bilstein shock controller, Samco intake duct, accel injectors, etc)
The suspension feels tight, even with 188K miles. It feels tighter than my 65K mile #1147 felt.
Fluidyne radiator
Carpets are in surprisingly good condition, just dirty.

First order of business is to pull the rearend, in order to replace the seals. Also pulled the plenum, of course, to replace plug wires/breather hoses/breather box gasket etc. New oil cooler lines waiting to go on, and of course the C5 brakes and A-Molds that I pulled from #1147 before selling.

Couple of pictures, prior to initial cleaning:

Here you can see some of the baked-in filth in the paint... the doors and rear bumper were most severely affected, but are cleaning up well.

Got my work cut out for me, but for under $10K I still think I did well.
