Z Progress

It's been quite some time since I posted an update on the 280ZX project. Today, I'll catch everyone up. For my US former military readers, Happy belated Veteran's Day and thank you for your service.

Tear Down Blocks

shedroom

In my last post about the Zed in March (See Strip Tea Z), I described the tear down of the donorZ, and even posted the link to the craigslist sale of the picked-over shell. We found a buyer, a guy who rebuilds old 240's, 260's and 280's, and he knew there was some remaining value in what we sold him. To make the sale work, I had stripped lots of good stuff, and stashed them wherever I could find a place in the small garage. Mostly, these parts were set inside the keeperZ (Zed). This had the unfortunate side-effect of reducing the interest in working on the Zed. So, this past weekend, K2 and I emptied the Zed of all of the parts we were storing in there. This created a need to deal with the shedroom.

Shedroom

inspected

When it was conceived, the shedroom was a "couple months" solution (See 280ZX * 2 = Y). Now, over 9 months later, it has persisted. Boo and I decided that we needed to embrace the shedroom, and set it up better than the basic pile of parts on the floor that it had become. Otherwise, the work which has stagnated will never restart. So, similar to the interior of the Zed, we moved all of the parts out... into the hallway. Then, we installed a set of monster shelving and organized the parts onto it. This made the space much larger, and more useful... and allowed for all the other parts from the inside of Zed to fit. So, now we have the Zed empty of spares, and parked in the driveway (under a 10x10 canopy), ready to be worked on.

Auto Shop Class
K2 has started an auto-shop course in high school. This is the only such course available in the state of Oregon, and has a class size of less than 20, so it's kind of a big deal. Gone are the days of every high school having a shop like this. As I said, Oregon only has one. From this class, K2 is learning things that he is now teaching us. Included in this growing list of teachings is the multi-point inspection.

Inspection

stripped

K2 wanted to do some work on the Zed after we emptied it of spares. The auto-shop class is much more focused on mechanical than body or interior stuff, and he felt that doing classwork stuff would help him retain the teachings. So, he set to doing a full inspection of the Zed, recording his findings for us to evaluate. My sole influence was for him to write everything down, and not to filter anything out due to concern that we wouldn't want to do the fix. Similar to having the boys decide if a car was purchase-worthy, I want the boys to drive what is or is not in need of repair, based on diagnostics not cost or convenience. The list was pretty long, including the brake booster and radiator replacements, and a full tune up. That's totally fine. I tell them that money should only guide "when" not "if" something should be done. If it is a safety item and you can't afford to fix it, get a bus pass until you can.

Strip

Sunroof Returns

With weather changing, our window for getting the grinding done before winter arrives is closing. I don't think we're going to get the exterior paint-ready before then, but I think we can get the old paint off before pushing Zed back into the garage for body-fill. How we manage the sanding of that body-fill will be the adventure that follows. With K2's preference for mechanical, I expect he'll get after the tune-up and radiator replacement completely independent of the exterior work. After another weekend day dedicated to the paint, we have stripped the fenders, hood, driver door, rear quarter panels, and roof. All that's left is the rear hatch and the passenger door: both of which can be done on the front porch. So, we are ready for the seasonal rains and the winter that follows. We can figure out body filler along the way.

Sunroof

the grind

The early 280ZX delivered with a sunroof. The donorZ was a late 280ZX, and it shipped with T-tops. Our early model, however, arrived without the sunroof. The prior owner who made such memorable decisions as removing the less-than-one-pound rear speaker panel, gutting the interior for weight and hacking the wiring so the fuel pump and ignition were triggered by switches also decided to remove the glass sunroof and weld on a patch panel. And weld it poorly with gaps and burn-thru. To resolve the leaks, the seam was "sealed" with duct tape. Neat. I had a couple of hours on a Saturday, and the sky, while threatening, wasn't supposed to open up with rain for a couple of hours. So, I backed the Zed into the driveway. The duct tape removed with a razor blade, and within about 15 minutes I was able to knock the patch panel free simply by hammer a wedge into the spotty gap, focusing on the welds. I cleaned up the edge with my angle grinder and then switched over to my wire-brush. I cleaned up all the spots where I'd used the chemical stripper, removing the flash-rust that appeared in the time since. It is interesting how the steel wire brush stripping doesn't leave the surface susceptible to flash rust, but the chemical does. One more factor to include in the mental-math when I look at paint removal in the future.

That's it for today. Thanks, as always, for following along-

Daily Driving

At some point after my trip to Boston, the clunking noise coming from the front end of my 2001 TDI Jetta (Flash) started to really get to me. I don't know if it was the weather changing or the car's growing desire to turn right, but I knew something was going sideways. Today's post covers that saga.

Rebuild Parts

from MetalMan Parts

I trolled around the internet and found some good pub on this rebuilding kit from MetalMan Parts. So, I hit the site, and made some decisions. First, I got the fuller kit with the TT rear bushings. While that cost a little more, I figured this was a replacement I probably wouldn't be doing again. I also got new front struts (COFAP for comfort, recognizing the TT rear bushings will stiffen the ride) and new strut mounts. I had read good things about a 1" lift kit from Evolution Import, and I got that too. A few days later both shipments had arrived.
Upon inspection, the MetalMan kit was pretty fantastic. Every fastener that needed to be removed had a replacement. They sent both sway-bar bushing sizes and replacement clamps. It looked great.
The Evolution Import kit wasn't as impressive, but it looked like what I expected from the instructions online. It was shiny and relatively simple. I ended up not putting the rear lift in, and the Jetta sits flat with out it.

Destroyed My Arms on My Arms
I set aside the weekend to install everything, with the recognition that I would need to take the strut assemblies somewhere to get the springs moved from the old set to the new set. I'd also need to get the alignment done somewhere. Otherwise, I felt I could do everything else. 9:AM Saturday morning, I pulled Hapy out of the garage bay where he'd been resting since our active Summer and put Flash in his place. By 11:AM, his was on stands, the Panzer plate was off and I had my plan of attack. I'd start with removing the control arms. Once the old ones were off, I could easily get at the sway bar bushings as well as get the struts out.  The sway bar links came out with little trouble, but the 2 18mm bolts with point towards the rear were a little tight. I had to work them pretty hard, and I found my arms started to get sore. But that was nothing compared to the 2 bolts which fed up from below. I tried PB Blaster. I tried a propane torch. I tried this stuff from Amsoil called "toolbox helper". I went back to the torch. By late-afternoon, it was clear I wasn't going to get either of them off so I soaked them with the Amsoil stuff and let it sit overnight.

Sunday morning, I ate well, enjoyed coffee with Boo and then went back to the bolts. Within 30 minutes, I'd concluded that the soaking hadn't helped and I was stuck. My arms were really aching from the day before, so I started looking for options. Since the front end was in pieces, I couldn't easily take the car to someone to get the bolts off, so I hit craigslist for someone willing and able to do the work in my garage. I found a father-son team, and they were happy for the work.

MobilePDX

now that's a breaker bar

MobilePDX is a father and son team who have worked on cars for years. Courtney is around my age (dirt is older, the internet is not) and has been wrenching on cars since he was a kid. They were organized, clean and left my garage in better shape than they found it. I'd originally intended to have them just get the 2 bolts off and swap the struts, but once they got going, it was just easier / faster to have them finish the job. They were able to get the passenger side bolt off with a breaker bar and youthful strength. The driver-side had to get ground down with an angle grinder. I'm not exactly sure how they got the bolt out after that. They followed my original plan from there, verifying my thinking... which is always nice.

Aw Nuts
After MobilePDX got everything back together, they discovered that the front caliper bolts were not grabbing into the hubs. Upon inspection, the threaded holes weren't threaded anymore. Neat. The proper repair is to over-drill the holes and thread in a helicoil (or something similar). That is what Courtney said and the chat-rooms agree with him. Others have used an oversized bolt that is so widely available both on the internet and the FLAPS (friendly local auto parts store), I'm inclined to think it is becoming a widely endorsed solution as well. While I sort this out, Flash sits on jack-stands and I am driving Hapy every day.

Hapy Hapy Joy Joy
I'm sure if I look back into this blog, I have many references of going back to driving the bus after a period of not driving him and expressing the pure joy of driving the bus. It really is awesome. The smiles, waves and conversations happen as much in the wind and rain as they do in warm summer. That's pretty neat.
I have continued my experimenting with the shift-point, shifting now around 3400RPM. This allows for the engine speed (when dropped into gear) to still have some turbo influence. So, he's got even more zip than the old 1700 had from the bottom to the top.
I just put 10 gallons into the tank, and I got over 28mpg since the last fill. Since there's a lot of city driving in there, I think I could have a viable city/highway mix guess: 27 city / 33 highway. Pretty fantastic. It hasn't been all smooth sailing though.

Fix-It List
On an exceptionally cold morning, I discovered that the dash vents weren't quite aligned properly. When I went to fix it, I accidentally pulled the wiper electricals out of the switch. Turns out, that bundle of wires needs to go through the hitch in the center of the plastic "Y", not around it.
After fixing that in the parking lot at work, the heat is suitable for clearing the windscreen from mist or fog, but it smells like diesel exhaust. I need to locate a source for fresh air before I drive Hapy into real cold weather.
The fuel gauge needs to be replaced. I still don't know the actual capacity of the tank and guessing based on the mileage when I last filled isn't a reliable measure. Cold wet weather isn't the time to guess if you need fuel.
I didn't re-install the door seals after I painted the top 1/3 of the bus. This creates a pretty good breeze when travelling over 35mph. I need to install them. Of course, the old ones were pretty beat up, so I need to order another set.
The bus still has some rattles, and I think one of the door skins is the main culprit for most of it. Also, the other jalousie window is now making the noise the rebuilt one used to make. Perfect. Time to rebuild the other window.
Last, the brake warning light flickers at me. This usually happens when I remove or do something around the battery. Since I had to charge the battery before moving him out of the garage, this was self-inflicted. I think there's a fluid leak near the master cylinder, though, so I may have to do a fuller brake overhaul soon. Either way, I'd like so much for the flicker to go away, or just never happen.

That's it for today. Like usual, if I'm not posting, its because I'm working on one of the cars.... or traveling. Once the front brakes / hubs are solved, Flash will be driving again and I'll start knocking down the list above for Hapy. The good times never end. As always, thanks for following along, and please pray for snow. I'd really like to get some gravity testing in this winter and our farmers need the snow-pack for summer irrigation-
