Losing coolant while compression #s are good?

Did the cranking compression test on my 87T. Both end cylinders 170 psi, center pair 155/160. This engine slowly loses
coolant, apparently invisibly. One plug looked awfully clean (sign of coolant cleaning I am told). FWIW engine was well
warmed up also & ignition disabled.
Have not seen any visible hose leaks or radiator leaks. Car is semi high mileage (231K), and puffs some blue smoke at idle
(valve seals or turbo?), but the coolant leakage had me thinking head gasket. However the compression readings seem to
indicate otherwise.
Bentley says do a pressure test and see what happens. Anyone got a good homemade solution for pressure testing w/o SAAB coolant tank adapter?
Any thoughts on coolant consumption?
