Seized piston impact options?

[jtoomasson at yahoo.com (Jeff Toomasson)]

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 pistons have what would seem to be above-normal carbon deposit for a 70k mile motor, but nowhere near the amount seen in #4....
 
3) don't have a rubber/wooden mallet - would the handle end of a screwdriver work?
 
4) I'm not really opposed to cracking the block open, but the goal was not to spend too much $$ on this motor - it was only supposed to get me by for a year while I get my 
X-flow turbo 3A going. (that's assuming buying all near bearings, rings, etc...)
 
>From my uneducated standpoint, there is a saving grace - the #4 piston, which is the one that appears to be stuck, is stopped near the top which would seem to make it plausible that I could give the area in question a light hone myself without having to drop the crank. Am I off-base?

Thanks for the input - Jeff

1. Please define crud (ie: carbon deposit or water/crap/oil deposit ?)
2. pb blaster for a week, then breakerbar with a long breaker bar should
turn that puppy over
3. alternatly you could use a rubber or wodden mallet to tap atop each
piston head to "dislodged presumed rusted rings from the chamber wall"
4. personhally I would take the bottom end out, bearings/cranks and all, and
then push the pistons out, if there IS rust (due to water deposit) I dont
think turning a rusty crank is going to help against" scarring the surface
of the bearing area on teh crank."

just my 2 cents worth.
