Methinks heat transfer may become an issue.
With less mass on one side of the liner, the other side would experience a
greater degree of heat.
Don't really know if it would be enough to cause problems like warping,
etc.

Subject: [TR] TR4 - broken piston liner
My dumbest move yet - and that's saying a lot.
Some may remember that when investigating my engine bang, I discovered a
burr on the connecting rod bearing seat on the crankshaft, which had
ground
a groove in the bearing. I did my best to remove the burr with emery
cloth
and fine sandpaper, and buttoned up the engine. Today I decided to fine
tune
my repair, and having detached the rod from the crank I asked my partner
to
bump the engine around so I could get at the bad spot on the crank. To my
horror the rod got stuck on the wrong side of the crank, jammed into the
piston liner, and broke off a crescent shaped piece of liner about 1 1/2
inches long, where it protrudes from the bottom of the cylinder bore!
So, my obvious question is, can I drive it this way? The piston does enter
the broken area at the bottom of its stroke, but all the compression is
way
above, of course. I don't expect the liner is cracked upwards above the
break, but who knows? I think its impossible top buy just one liner
although
I might come across a used set, I suppose. What further damage might I
incur by not replacing the liner?
As always, thank you for your help.
