Adding fluids and fixing the leaks

Getting close to starting the engine. Final steps include adding coolant, gearbox & engine oil. We had a couple of leaks to fix along the way.

The first leak was from the temperature sensor. After a lot of fettling, we found a small rubber o-ring that fits inside the outer brass nut.

And of course, the valve cover leaked. This was a bitter pill to swallow because I order the "uprated" gasket and silicone sealer. Both products failed around the rear "half-moons" and head bolt. I pulled the cover and resealed everything with Black Permatex.

I also took the opportunity to install the hard-to-find-and-expensive "Jim Clark" Lotus horn button.
