Sooooo close.

A lot of things have been crossed off the list in the last couple of days.

Swirl pot is complete:
This involved welding shut the holes that were original to the spare pot I had. The only take away I had from this, was this: Use a good welder for any welding you need to do. Although it did not ruin the swirl pot, I could have easily had a major loss if something had gone slightly wrong with the crappy welder I was stuck using. Once I was done with the welds (which were poor at best) I 'spackled' over top of them with some epoxy. I'm told that this epoxy is specially designed for ultra deep water performance, so I am not too worried about a little pressure from the coolant system.

Radiator is reinstalled:
I am especially proud of this feat. When removing the radiator, I broke off both bolts that hold the bottom in place. I was afraid that by trying to weld them back into place, I would blow through the radiator walls, and need to purchase a new one... Not a purchase I would be looking forward to. I decided to use a type of epoxy made by Loc-Tite that is supposed to replace welding. Whether I did not prepare the metal correctly, or I didn't mix it correctly, it didn't hold. As I was putting the radiator back into place, the epoxy broke off clean from the radiator. So, I attempted something that I had never tried before. I brazed the bolts back on. For the first time brazing, they came out beautiful. A little crooked, but awesome.

Coolant system is nearly complete:
With the completion of the above two tasks, the only thing I needed to do is complete the plumbing. I cut the pipes that run the length of the car, just below the heater hose plumbing. I don't plan on driving the car when I would need heat, so this made everything much easier. Of course, since I had plugged the holes in the swirl pot, I needed to eliminate the heater from the plumbing system anyway. While I was running the hoses, I found I needed a sharper bend than the hose would allow. I started the search for some stainless bends. They came in at about $30. When I was staring at the car, I realized that I had a perfect fit for the application. When preparing the coolant system, I cut off a piece of pipe with a nice bend in it. The only problem was that it had a little return hose line inlet on it. No problem, a little brazing, and it was perfect!

The engine is re-wired:
I only need to check that all of the sensors are reading correctly when the car is running. I am a little concerned about the VR sensor, and the O2 sensor. Nothing a little more re-wiring won't cure.

Things are getting done

The brakes are complete. There is a few little things that need to be cleaned up, but they are done. The rear brakes are installed, I just need to put the e-brake cables back on the levers. I am holding off on doing this until I have the cables freed up. I also need to re-attach the cables to the frame, as the original clips to hold them in place don't anymore.

I have also installed the alternator, and alternator belt. I needed to go to a shorter belt than I originally had picked out. I ended up using a 46.3" belt. I am very happy with how everything lined up, but I haven't run the engine with everything in place yet... My belt tensioner ended up working very nicely.

I've spent a few hours re-wiring the engine as well. I have the new engine side harness complete, and only need to fabricate a bracket to hold the connectors in place. I have also gotten the car side harness ready, but it will take some routing, sleeving, and labeling in order to finish it.

The seats need to go back in the car, but one bolt on each seat is completely seized. I think the only way to fix it is to drill out the seized bolt, and retap the hole. Since the original bolt is ultra hardened, I don't know if that is going to work though.

Right now, I think the highest priority thing to do is get the engine wiring complete. Once this is done, I can start trouble shooting it (again). The coolant tubing is being bent by a friendly exhaust guy, so that will be next. Once this is done, I can start the car again. Then more trouble shooting.

So the current task list:
Finish engine wiring
Check fuel pump and O2 wiring
Weld and complete coolant system
-Tubing to and from swirl pot
-Heater hose removal
-Heater tubing removal or renovation
Check cooling system is working (at least pumping coolant)
Finish exhaust system
-Weld, smooth exhaust tips
-Finish rear mesh and frame
