Kind of what I was figured, but I needed a gut check. While I have the SC off the engine, I'm going to add a drain to the snout to facilitate oil changing in the future and I figured at a minimum I might as well change the coupler at the same time. I'll do a write up on drain set up so we have it for future use.
