[TR] 1)Engine Block Interior, Liner Paint &2)Venting

[A Daniel Cronin]

Have thoroughly cleaned the interior/exterior of the block and head and
painted the interior water passages and push rod cavity's and crank/rod
areas with glyptal (also the top surfaces of the head where the rockers are). 
Was wondering if one could (should) also use this material on the
external parts of the piston liners exposed to cooling liquids?  

Another
question relates to the alloy rocker cover with its tiny pin hole air vent in
the supplied filler cap.  Is this adequate to properly function the way the
stock filler cap did?
