[T3] motors coming out!

[Keith Park]

Wow, split cylinder? These werent slip in 88's were they? :-)
The cylinder set was new with the second build, and I removed the jugs WITH
the pistons last 
disassembly, so the pistons never left the jugs.

Yes, with the second build and the new Keith BLack pistons I checked
EVERYTHING, all the gaps!  And yea, you really NEED to, Ive also seen
insufficient end gap.

If you replaced the rings, they could be the problem. It could be due to
dirt in 
the groove under the new rings, or it could be that the new rings did not
have 
sufficient gaps.

I once got a set of rings from Berg that had not been gapped at the factory.
I 
don't remember the details; IIRC it was just one of the rings for each
piston, 
possibly the top compression ring. I had neglected to test each ring in a 
cylinder bore for fit beforehand, so when I forced the cylinder over that
ring it 
split the cylinder. I couldn't believe that this could happen, but it did.

I've also had engines where I was careless about cleaning out the ring 
grooves on a rebuild, so that there was engine crud in the bottom of the 
groove that kept the ring from going all the way in. That crud had built up 
because the old rings were worn, leaving room underneath them, but the 
new rings needed that room.
