Found this article.The last 2 parts I find particularly interesting.
Modifying the Thrust bearing as stated in the article makes a shitload of sense, since it gives the thrust surface a direct supply of oil.Mike, whats your opinion on this?
The last part makes alot of sense as well.Its very feasable a current flowing from the bearing to the crankshaft(or vice versa) could break up the distribution of the oil film on the bearing surfaces.
