Seized piston impact options?

[txrocco at sbcglobal.net (Patrick Bureau)]

well if you are asking my personal opinion, here it is

if a cylindder is "stuck" and you beleive it was cause by some amount of
water, if it was my engine, I would strip it and do bearings maain/rod, rod
botls and ring with a honning, this is very basic rebuild , this does
permits you to inspect all important components of the block, rust on aring
is and will end up in the long run lead to damaging scrapes in your
chambers, if there is rust deposits around the crank this can lead to
bearing slipping out of place (forget the term for it) but can lead to some
expesive repairs (spun bearing job ie: .. new block)

its your call... but if the block does nto turn over with a ratchet freely..
that is what I would do.

->1)  Crud was all of your above!  Some (but really not that much)
->rust, lotsa a carbon. Probably about 2-3cc's total. The other

->for a 70k mile motor, but nowhere near the amount seen in #4....

->>From my uneducated standpoint, there is a saving grace - the #4

->give the area in question a light hone myself without having to
->drop the crank. Am I off-base?

->Thanks for the input - Jeff
