Hi Alan,
Although the center cap can be removed reasonably easily, after removing the
pan and oil pump it is pretty difficult to remove either the front or rear
main cap because there are bolts which pass through the engine end plates
and thread into the caps themselves.
I have changed the crank in a 100S engine without removing the engine from
the car but when one considers that the front cover, timing chain, engine
front plate, oil pump, gearbox, clutch, flywheel, and engine rear plate have
to be removed, it really isn't worth the trouble.
I would however suggest that it is much more likely that you have spun a rod
bearing than a main and, if you caught it early enough, you may be able to
just change the rod bearings, although that too is pretty unlikely.

Hi -
I need to take the main bearing caps off the motor of my Atlantic (same
motor as a 100) to check if I've spun a bearing. I've been told the caps are
press fit into the block.....
Is there any way to remove them with the motor in situ... or do I have to
pull the motor and take it to a machine shop. I really don't want to yank
the motor on this thing (the motor otherwise is in great shape)... I suspect
it just has a spun/scored main bearing, everything else is like new.
Any advice apprciated.
