On my 1990 4runner there is a squeaking coming from the same place. This is because my alternator bearings are shot so you might be in the same boat. As for the cylinder boreing, you have to take it apart to find out. A honing of the cylinder sleeves might be in order but if you bore them the pistons from the kit may not work.

you dont order the kit until the machine shop tells you what size piston to order. Period.

If it was me i'd take it apart first. But if it's not blown up you should be okay I would think.
