 +The hole was drilled in three size stepped bits. \\
 +Then the fitting was clamped in a vise, the plug pushed hallway on the fitting and snugged up with a wrench. \\
 +To test how it would hold under pressure, 100 PSI was applied from the opposite side and the fitting popped out. \\
 +Another test was done after the fitting was reinstalled and it held app. 50 PSI well. \\
 +But, for testing crankcase pressure, you should be testing more than a 1-2 PSI anyway. \\
