Drain the oil rails with the 2 plugs BEFORE removing the injector... this will mean almost NO oil will get into the cylinders, which means less time cranking the motor to purge the cylinders later, which means less likely to hydrolock the motor, and also easier on your batteries and starter, and also a TON LESS MESSY! It takes all of 5 min to remove these plugs... why wouldn't anyone do it???? LOL
