Toyman,
It isn't really a gush. It is a light mist that coats each time the locker is engaged and disengaged. It really isn't much, but it is more pronounced on mine due to the location of the air valve. As it mists, it hits the right side of the motor and a small amount lands on the exhaust manifold. If it gushes out, I am going to worry. If you lay your hand over it on release, it leaves a small coat of gear lube, but no drippage. It only begins to drip if the locker is used (on & off) on a regular basis. Sound like yours?
