New bolts are $9 ea, they come with some loctite on the thread. To make it even better some people drill a 1mm hole thru the bolt head and use steel wire to secure bolt to the oil rail. New bolts with loctite on the thread have a circle on the top of the head. This is the "must check" thing.

That engine was extremely dirty. Does it worth fixing?
