he just bought a house so he wants to get this back together as cheap as possible, as it would be a waste to spend the money on the 3.1 when he can build a 3.4L for the same money.which wont be till next year since he just bought a house.

so the plan is new ring set, 6 new hyper psitons and do a quick flexhone job to get the rings to seat.

my thoughts on the bearings are just to reuse the originals since they are worn in anyplace that needs clearance and they dont look bad.

what do u guys thing would u resuse them or would u slip new bearings in there even though the crank has some slight scoring from dirt passing threw.

the engine ran perfect, had great oil presure before it was torn down, it just had low compression in num 6 as the second ring was broke due to the cracked ringland
polish the crank and replace the bearings. The additional cost isn't that much when you consider the total rebuild cost. Its best to do it right, just in case he needs to put that 3.4L off a little longer.
