I have a '98 Z that one or possible more crank bearings that spins for about 30 seconds after I shut the machine off! *It has 1800K miles on it with me owning it since 350 miles. I've taken very good care of it, updated all updates, stator, cdi box with several other misc. items that have failed. My question is, with it apart to replace the bearing(s), is there anything else I should do when I'm in? *Do I install new pistons, rings, hone out cylinders while I'm doing this work? *Obviously will check compression and meansure the ring gap etc. before doing the work, but should I just do it? *I intend to keep the sled a couple more years becasue I like it and have stuck a share of ching into it. Just looking for some honest advise before I go ahead with the work, thanks.

It's going to cost you a little bit of ching to just get the
crank issue fixed. And if you're in that far into the motor,
you should see what else needs attention. Is the PTO side
crank bearing making the noise? Check setting of oil pump
and verify that it's working correctly. Look into maybe
having you oil gallies drilled out to get more oil to those
bearings. Was this motor fogged?
