Beginning Engine Rebuild- '72 B

[Mike Snyder <tperfect@teleport.com>]

OK,

I'm going broke on oil...Time to rebuild the bottom end, I think (head
was done 3k ago). Compressions are approx. 159psi on 1,2 &4 and, alas,
112 on 3. The engines been using about 1 qt. of oil every 150 miles,
with no oil leaks, visible oil fouling of the plugs or blue
smoke...engine runs strong. Due to smith odometer :-) I think the engine
has about 75k on it.

Any suggestions?
