I went to look at a Viggen today and while looking at the motor, I noticed oil coming out of the top driver's side of the motor. Upon looking closer, it looked like something used to be bolted there but was no longer. While idling I could also feel air pushing out of this same hole.
Useless without photos, I realize, but any idea what I was looking at? I'll add images shortly.
