During the second work session of the day I had to remove one magneto and one engine vibration isolator to install a restrictor fitting for the oil pressure sense line. Once the restrictor, magneto and vibration isolator were installed I carried out the final torquing of the engine mount bolts. Three washers were required under the castle nuts for proper positioning of the castle nuts for cotter pin safetying. Next I installed a fitting in the cylinder head for the maniflold pressure sense line. Lastly I worked on reshaping the crankcase breather line to fit my engine and firewall configuration better.
