The bolts with blue on them are aluminum bolts, which once torqued to spec, are stretched. re using them will not be torqued to the accurate value, plus there can be a hairline crack/break in them that will eventually break off and leak.
Blue = replace (required)
No blue = replace for peace of mind/not a bad idea
