Hmmmmmmmmm. Lets see....the oil is in the oil a pan seperates the crank from the oil. So what are you actually cutting through? If you wanted to make your crank lighter and balanced, then thats another issue. You are not actually cutting through oil.

knife edging is what he is referring to, its less weight on the crank so the crank will spin up faster (less rotational mass) just make sure you balance the crank by itself and then balance everything as a system before you run a knife edged crank

Re: ls crank question... (temp)
I would knife edge a crank on a daily driver.Theres just too much harmonics going on in an engine,and the counter weights also act as a dampner.Drag cars have a hard enough time with knife edged crank.There usually isnt too much oil for the crank to slice through,but it does help the counterweights cut through the windage.If you do take off weight,dont do more than 2 lbs,and make sure the crank gets balanced with the crank pulley and flywheel you plan on using.
