Dave's 1971 1302 Not-So-Secret, Secret Project Build

hahaha, yeah, I know exactly how fragile they are. Once installed one in a rad hose adapter without being grounded. When a brass sensor grounds through the coolant, they dissolve real quick!

Hey Steve, 320.028 is exactly the sensor I need...but so far haven't been able to find anyone who carries one. Got any sources down-under?

Tonight it was back to work, and to start off with...back to the lathe.


What I ended up making was a temperature sender bung and dipstick tube for the dry-sump tank. Hopefully I can convince my buddy Gord to TIG weld them into the tank tomorrow, and then I can pop that back into the car.


From there it was onto the car, and the next major phase of construction. I finally got the metric Nutserts that I ordered in. They took three weeks to get here, but when they finally did the counter guy at Acklands-Grainger actually drove them 45min North to my house! The nutserts allow me to mount things where I can't reach the backside for a traditional nut, and where I don't want to wreck the paint with welding. So, at this point that probably means the whole car! The ones I order are shown to the left. With the serrations I've never had one spin out me, but always match material (steel to steel, aluminum to aluminum) so that if I ever did have one spin, I could probably tack-weld it to solve a problem. On the off chance you haven't installed these before, and decide to get some, don't buy the "special tool". The next size up nut (so the bolt passes through) and two washers is all you need to install them.


With the Nutserts in, and the swaf vacuumed up I was able to mount the Accusump for the final time.


With that mounted, it was time to start thinking about the lines and Accusump valve. I wanted something a little more accessible this time round, but also something that would remind me about valve #2 which will be the oil-tank cut-off valve. CanNOT forget that one! Here's where I think its going to go. With the valve in the closed position (as in the photo) the handle totally interferes with the parking brake and is definitely annoying/noticeable. When in the open position, however, it will lie down flat against the tunnel and be completely out of the way.


In order to continue the Accusump lines, and then make the mounts/tie downs for the valve, I need to know where the Oil Cooler Thermostat is going to go. The Accusump line will Tee into the outlet, which goes to the engine, so I have know where that will line up so I can put the bulkhead fitting in. Making oil lines like this is one part being able to think in 3D, and two parts having a tonne of fittings on hand. You want to be able to try different degree fittings, and then switch it all up and re organize. The problem, of course, is that as you start building lines you start eating into you stash of fittings! Fortunately I had enough to figure out that the combination of a 45 and 90 will allow me to get the lines right into the thermostat without binding up the lines. Even though this is all well hidden under the car, at least I know it will be neat and orderly!


I was going to keep going, but realized that I'm missing one fitting I need, so I might as well wait until tomorrow...
