1996 magnum 425.  Just started leaking oil out of weep hole near bottom of engine on shifter side.  Leak stops right away if you restart engine.  Leaks 3-4 ounces and then quits.  Even left quad inside overnite in case vent for oil system was frozen.  I believe there is a vent some place for the systwm but am unable to find it.  Thanks for a help.  Granpahoof
