Jack,
I fought this battle. Finally I installed a pressure gauge in line :

brought the cylinder under test to TDC then locked * and pressurized it.
When the gauge started to rise, the culprit was found.

* pressurizing the cylinder at TDC will cause it to move (duh), usually
putting it in 4th gear w/E-brake was sufficient. Bring the air pressure up
slowly.
