[TR] Update on TR3A from 2 weeks ago

[Tony Drews]

I wonder if the head re-torque after warming up the engine hadn't 
been done.  I'm always amazed at how much movement I get on the 
second torqueing.  Also, 0.006" difference in liner protrusion 
between two adjacent liners is not ideal.  A little difference from 
side to side will work as long as it's consistent.  0" protrusion 
isn't great.  You may want to try Randall's trick of the thin copper 
wire glued / soldered to the head gasket.
