375hp banshees Posted May 15, 2021 Report Share Posted May 15, 2021 Around crank I Assume. I don't Remember if you could put a speedy sleeve In the area or not . even if it's Not Grooved, it at least will give you a little larger OD and Might seal?Sent from my SM-A505U using Tapatalk Quote Link to comment Share on other sites More sharing options...
