I wonder if Ehrenburg's process is based on his recommendation to only put 4 quarts in the pan. I guess he thinks that is enough oil to avoid starving the pump but keeps the oil level away from the crank. Not really sure. Been awhile since I read the article.
Not sure. Haven’t read or heard his gospel before. But if you built it according to the height/level with 4 quarts in there I’m pretty sure stuff would hitting it and creating havoc.
