"After years of messing with a tank I built for our modified roadster that was theoretically correct, I broke down and bought a 4 1/2 gallon Peterson tank on eBay for a song. The difference a professionally designed and built tank made was night and day as far as de aerating the oil. Tall, multiple baffles, swirl inlets and a stand pipe up the middle make it work. Be sure to follow the makers advice about vent tube diameter and routing."
Great advice, building a tank that does what it is supposed to , number one job of the tank it to separate the air from the oil, and the tanks built by Peterson and others do a great job of this. The high tech Honda pan that Tony showed is good if you happen to have a multi-million dollar engine development program but not many of us have that ability.
