Thanks very much for your quick response.
I don’t think anything reached my clutch because I wasn’t having any clutch issues and everything looked dry when removing the starter and looking at the clutch.
Here are some references that I’m trying to figure out how they may relate to my situation.

Post 21 talks about gearbox oil mixing in. The slave cylinder definitely had a smell to it when I pulled it out. It wasn’t exactly the same as gear oil but had me wondering if some mixed in, and if so, what that means in terms of failing seals.

Post 38 suggests replacing seals if there is any goo. Looking at my seal, it definitely doesn’t look clean and not sure if the goo has degraded it at all. I’d rather not mess with things if I don’t need to but want to make sure I fix things right and reduce the chances of future problems while I have things apart.
The following two posts talk about the bearing grease not being enough on the new slave cylinders. I bought an oem cylinder from BMW as you suggested.

Post 11 - add grease with a pencil eraser

I don’t see post numbers but in the post from November people talk about adding grease but seem to say the bearing needs to come out to avoid airlock when pushing in grease and to get the grease in the right spot.
Thanks again.
