Advice needed. A journal cap came off!

I would check the run out if that journal with a dial indicater and check the threads in the block. If I could not find any more wrong than what I've seen so far I would put it back together.
A forum like this gets responces from those who race every weekend and those who drive near the speed limit to a local cruise-in once in a while. Money is always a factor too.
Some will buy a new radiater while others will try black pepper rather than spend the babys' milk money on a bottle of Barsleak.
I wont suggest you use a piece of a leather belt for a bearing ( that has been done ).
Just weigh every opinion against what a close inspection suggests. Good luck
