Decent milestone today - I drove it to work. My commute is about 25 miles, mostly freeway. I figured it's a good shakedown since I'm driving it downtown for Radwood in a couple of days. So here's a kind of "state of the project" report:
There are still some issues, for one thing the heat is still staying on. I have replaced the rod clip connector thingy under the dash, and that didn't fix it, so I bought a new heater control valve and a bunch of silicone tubing to replace the vacuum lines under the hood. Well, the old control valve seemed to be working OK, I could push the lever in, put my finger over the vacuum port, and it would stay in. Also, and more importantly, it is absolutely crammed in there between the engine and the firewall and it's going to be a huge PITA to get it out, so I left it for now. I did replace the vacuum lines, but it doesn't seem to have helped, I still had heat on this morning. For now I'll live with it, the weather is getting cooler anyhow.
Other than that, mechanically it seems to be good. I still get an occasional no-start because the connectors for my reference sensors like to work their way loose. Easy enough to fix, but still annoying.
New radiator, water pump and everything seems to be working fine. I did add a bit more coolant the other night after driving it around town some. Hoping that's just the bubbles working their way out of the system. There are no leaks, the gauge stays mostly in the lower third, and no signs of coolant on the dipstick, so I think I'm fine.
The drivers side window is missing part of it's frame inside the door, so if you roll it down all the way, it rattles like crazy. I will probably replace that door card while I'm at it, it's pretty torn up from being removed and replaced so many times. The interior in general still needs a fair bit of attention, from the cracked dash to the non-working clock and odometer to the still-iffy carpeting.
My self-rebuilt alternator seems OK for the most part, I haven't run into any dead batteries, and the gauge reads in the middle. The one issue I ran into was when I was driving at night last week with the headlights on. When the car dropped to idle, the "!" warning light would come on. If I revved it up, it went away. My lights are also hopelessly dim. I know there are a bunch of solutions for that issue, I'll look into them over the winter, too.
After driving modern cars for so long, stepping into a semi-restored mid-80s car is a pretty major change. The NVH is of course much higher. I know my control arm bushings are shot, and you can hear them squeaking going down the road. The ride is certainly firm, even with stock suspension and Konis. But you can actually feel things through the steering wheel, and it's nice to be in an old-school manual. I love my modern cars with their conveniences, but this thing is the perfect change of pace from all that. I wouldn't want to drive it every day, but as a toy, it's perfect.
