crank scraper question
Trays keep the oil from being pulled up
Crank scrapers are removing oil that's coming back down and or hanging on the crank ,any extra weight kept off the crank is less drag, balance interruption, and helps it back to the sump.
I've always baffled pans, windage trays when available and or a scraper.
I even made one for my slant when i was 18 yrs old.. still have the fkn thing!
