Are WAZOO Maintenance Days Still Happening? - Page 2 - ZR-1 Net Registry Forums

Hello ZR-1 Net Registry and WAZOO members!

My name is Raymond, I'm in the northern Virginia area and I've been lurking for a long time. I have even met a few of you at various meets over the years (i.e. Katie's Cars & Coffee in Great Falls)!

I decided to finally hit the join button because I was curious if the WAZOO Maintenance Days are still a thing in COVID times (I am vaccinated) and if are you accepting newbies?

I've had a 1990 ZR-1 for about 7 years, No. 729. The car had a pretty colorful life before I bought it, in that previous owners (it has had several) have installed exhaust before hacking the OEM one back on, removed the FX3 suspension, had the car resprayed, and even used soap to try and quiet a squeaky accessory belt.

In the time I've had it, it has had about 10,000 miles driven (~75k total) and the following work done:

Rebuilt harmonic damper
Rebuilt accessory belt tensioner
New fuel injectors
New water pump
New coolant hosing (mostly)
New oil cooler lines
New brake master cylinder
Fixed leaky passenger-side exhaust stud
Fixed leaky oil pressure sensor
New exhaust (Billy Boat, the OEM one rusted and fell off mid-drive and wasn't worth saving)
New coil-over suspension (VanSteel)
New LED headlight conversion
CHMSL bulb replacement
Serviced headlight motor gearbox
New alternator x4 (figured out the issue killing them earlier this past spring)
New hatch struts
Straightened out floor-pan (some PO had put a dent in it somehow, tilting the passenger seat to the left)
Re-sprayed rear bumper (car got a love-tap from behind)

I got the car when I was 23, and it was sort of a joint project car between my dad and myself, but I'll fess up and say that, while I bought all the stuff, dad did the heavy lifting on the labor; the work I've done involves all the lighting and related elements and the hatch and the endless joy of scraping sticky plenum gaskets off bit by tiny bit. I have some additional outstanding issues, but I would like to respect my old man's time and take full responsibility for this car's well-being and a maintenance day with people experienced in working on these cars would be a real confidence-booster and I have a shiny new 203-piece toolset that needs christening (and I'm sure will need expanding). The issues I'm looking at are:

1. Broken HVAC - in 2018, the head unit went non-responsive, dashes in the display, blows hot all the time through the defogger. Reading old threads around here, and having the shop that did the coil-overs try a functioning head unit from another ZR-1, all signs are pointing to a failed HVAC programmer. I bought the Batee rebuild kit, but have been procrastinating tearing apart the dash to get at it because I only just got the car back last October from spending a year in aforementioned shop. I have seen Batee's video on the subject.

2. Vacuum leak under the plenum; tested this afternoon following the handy dandy guide on this site. When driving, under heavy throttle, it feels like the secondaries are opening then closing intermittently. Plenum-side test with vacuum pump showed a very slow drop, about 1 in. Hg over 15 seconds; pump-side test showed no movement and the pump comes on as expected. This is a fairly recent development, it hasn't always been like this. Possibly related to HVAC issue?

3. More fluid leaks - the car still seems to be dripping from somewhere (not nearly as bad as it used to be). There's also another more or less clear fluid that seems to be escaping, notably when the car is tilted backward when jacked up on the front end; maybe clutch? Gear oil?

4. Wobbly steering wheel - usual downward right-to-left wobble common to C4s but bad enough that it will fail the next state inspection; seems a relatively straight-forward fix as long as it's just replacing the pin with an oversized one.

Cheers all, thanks for reading!
