Looks like my new to me Max IV has a bit of water in the engine. Not a big deal, I can change it. Should I be on the lookout for any long term issues from it? Also, noticed a wonderful clanking-screeching noise when turning to the right. Looks like the rear drive chain has a few frozen links. I gave it a liberal coating of PB blaster, and I'll let it sit or the week, my shop is 25 miles from my house and I don't have time during the week to get there. What are the chances of the PB juice freeing up that chain or should I just order a replacement now?

Never seen so many grease fittings in such tight quarters before. I can see losing a good deal of knuckle flesh maintaining this thing.
