Re: Power coating in the engine block lifter vally?
I believe the "makes the oil drain better" is an urban myth. Probably started by a pit crewman making a smartass remark to a question from a reporter. I do know that having the valley and other areas painted makes to easier clean the block and may also help in spotting cracks. Which on engines that are frequently torn down certainly is a benefit.
