Apologies for the repost, but I'm losing my mind and I forgot to change
the subject line.  I'm losing my mind.  This proves it.

Quick run down - my 52 TD was idle with fluids in it for about 30 years
until I
decided to try and rescue it.  I've pulled the engine and have removed
the cyl.
head and pan.  The unfortunate realization is that the pistons are
rusted into
the block solid.  Does anyone have any thoughts on how to remove them?
I've
tried tapping, pounding, and pursuading to no avail.  Two pistons are at
TDC (or
only a couple of degrees off that) and teh other two are (obviously I
guess) at
or near BDC.  Due to rust on the pistons and the connecting rods they
have to be
replaced, so worst comes to worst I can have the machine shop drill them
out
when I get the cyls. bored, but I would prefer to do it myself, both for

personal edification and, er, financial reasons (grad students don't
make much
money, y'know...)

Recently there has been a good thread on storing engines and trannys - I
guess
I'm currently going through a bit of an object lesson as to what happens
when
the DPO DOESN'T do these things... ;)

TIA,
A. Arabian
