Problem fixed: lower end, water in. No water out of witness hole

Replaced seals and water pump . Made my own pressure gage to check for leaks. For fitting I used 1/4 in galvanized pipe and re threaded to 3/8-14 , fit oil vent screw hole fine. used a rubber hose and small ball pump to pressurize. put air gage in line with a tee fitting . that way you wont over pressurize and watch for leak down
