1986 Nishiki Sport Bottom Bracket Grease leak
So yesterday I took my newly acquired 86 Nishiki project and removed derailers, resized chain, (all of which were new experiences for me) and essentially made it a beater single speed for step one in my potential new hobby of destroying bikes instead of just riding them.
The bottom bracket pic below has some grease seeping from it. Just wipe it away and continue with the Nishiki torture process? Lose sleep over some grease seeping? Trash dumpster the bike and go back to craiglist $50 bike ads that are 200 miles away? The ghetto'd single speed 52/20 actually rides very nice, with no noises, despite it's need for tires, trued wheels, and some tlc. I attempted to disassemble the bottom bracket while I was being so destructive, but was unable to get past dust cover removal, and a nut that removed very easily underneath the dust cap. I expected the crank to slide off with ease, but no such luck. I suspect I need some manner of crank puller.
Is the little bit of grease indicative of a bad frame, or it just happens on 28 year old bikes?

If you want to keep that crank, reinstall that nut a little tighter than it was before removal. OR, completely remove the crank arm and reinstall it with full specified torque on the nut. Then leave it alone.

IF grease is leaking out, I'd consider that a good sign. At least it was greased once.

Ultimately I'd like to keep the crank. I'd like to keep as much as possible, knowing that I'll have a pretty ugly single speed road bike or fixed gear beater bike. Based on responses I'll assume the grease is not a big deal.
