I filmed it while I was traveling to film Roadkill. Once we wrapped filming Roadkill in Gardena, California I drove to Torrance, California to the headquarters of Ace Racing Engines. There, I got to look at and fondle parts that I've collected over the past 12 months for an upcoming project car. This episode is about the very first steps in building the engine, namely measuring the oil clearances of each crankshaft main bearing. It's a sweet video that will help you when it's time to build your first engine.
