<VV> Problems with a 140 tear down

[Bob Gilbert]

JR,
I was thinking of something similar by way of an old metal pan filled with
diesel oil and leave the entire thing, plugs out, sit in it for a week.
Somebody told me diesel oil might do the trick.
Regards,
Bob
Ps but the dynamite might be more exciting! :-)

Patience instead of dynamite.

If it's on a stand which (I assume) rotates - try putting the engine
90degrees from normal and pull the plugs on the high side.  Put plenty of
Marvel Mystery Oil (or your favorite concoction) into those 3.  After a week
(maybe 2), put those plugs in and do the same on the other side.  Give it a
couple more weeks on that side and put it level.  Pull, or at least greatly
loosen the plugs and begin working the crank back and forth until you can
work it to the point where it will go a full 360.  This could happen right
away - or (more likely) take another couple of weeks with say 3 or 4 10
minute tries each day.  Eventually, you should be able to get to all of the
rod cap nuts.
Later, JR
