The valves are easy to explain. The engine is from a car, so it has hydraulic lifters. It has always run very quietly. The fan is a mystery. I'm not sure what they normally sound like, but there is one there and spinning! The two sounds that I heard were the engine rpm's, which I use for shifting and the whine of the transmission gears. It'll sound weird, but I really like that whine! These gears sound different from any other manual transmission I've driven. They sound heavy duty, or something, but definitely different! I'm hoping to try a longer drive tomorrow. Assuming everything goes well, it'll be time to put the hood on and wrap things up, from the project journal perspective.
