Thanks for the response and I'll check it all out this weekend and let you know 
what I find, which I think will be a head gasket failure.

So obviously a new problem. With that much oil on the plug and "tons" of smoke, 
I'm going to guess the piston broke somehow,
perhaps a manufacturing defect. Normally oil smoke is blue, but the blue color 
isn't always obvious, especially if the cylinder
isn't running at all.

But you won't know for sure until you've got it apart. Personally, I wouldn't 
bother with even a compression check, let alone leak
down. Whatever the problem is, will be obvious with the head off and the piston 
out.

Don't forget to check the ring end gap. New rings are often supplied slightly 
oversize, even when included in a liner set. And a
too-tight ring can lead to a broken piston without making any obvious noise. 
Lots of other possibilities of course, so just one
more thing to check.
