So, the amount of force needed to remove thermostat housing bolt on the left, vs the bolt on the right ... not that much different. Left one is out. Right one is missing its head.
I took some measurements and designed a "Dancing Chic Productions" custom knob for the valve on the engine hoist. The first draft took about 15 minutes to design in TinkerCad and an hour to print. It was a little tight and because I built it just to size. It broke in half as I tried to remove it. I expanded the center hole by 0.1mm which seemed to be the only dimension that needed fixing. I reprinted with 4 perimeter shells and 40% fill density which is a combination that makes for good strength with a reasonable amount of material cost. I used PLA - PET, ABS or Nylon would be 'tougher', but I have very good results with PLA and it is so easy to print. Plus it was what was in the printer when I went to run it. Since it broke on the shank the first time, I reenforced the part where it actually torques the screw by making it oval instead of round. Just putting more material structure to back the turning force. The finished product took about 2 hours to print and used ab...
I am fairly sure that ZEP engine degreaser is a gallon of soapy water. The ingredients say it has some chelating agent that binds metals to it and drags them into solution (I think other forms of EDTAs are using as anti-coagulants in medicine). Whatever it is - it works. And smells nice. Of all the degreasers I found at home depot - it was the cheapest. Step 1 - drop a piston is a small plastic tub that used to hold diswasher tabs with enough ZEP to cover the rings Step 2 - come back tomorrow Step 3 - wrap connecting rod in some carboard and cinch it up in a bench vise Step 4 - break off any piston ring pieces that are easy to grab with your fingers (do this so that the snapping action is pointed away from your face) Step 5 - tappity tap tap with a screw driver + hammer on the grimey stuck ring parts that are left until they fly out (see note on pointing the action away from your face). 2 minutes of set up and 5 minutes of tapping and the job is done. Should take me 7 more days to...
The car is buttoned up and ready to go It took me <2 hours to get the heads, valve lifters, valley cover, intake manifold, exhaust manifold, carb and fan on. I tried to put the thermostat housing / expansion bottle in place, but I realized I had to drill out one of the bolts and so I didn't have enough to hold it in place. The other one was pretty gacked anyway. It took me another 30 minutes to organize all the stuff I had for the car inside the passenger space. I tried not to shove too much into the trunk, since it still doesn't open. While I had it up, I used some "green slime" to stop the leak in the one tire that wouldn't hold air. I tested this morning and it seem to be good to go. I had to zip-tie the E-brake cables to the frame so they would stop getting tangled and dragging. I also zip-tied the clutch pedal rod to something that was sticking out of the transmission - otherwise it was hanging straight down next to the fire wall. The tow truck will come ...
