I was instructed to take a fitting that goes into the engine, tap it, screw in a brass screw w/ suitable loctite, cut off the screw and drill to 1/16" hole through the now blocked fitting. I took a punch and peened the fitting so the screw couldn't get into the engine (if the loctite did not live up to allegations). The mechanic liked my work and installed it.
