I don't think this is a problem, but every time when I remove the screw/dipstick on the out drive to check oil, it blows a little puff of air. I'm not losing any oil. Does this mean there are no leaks? Is there a vent that could be plugged? Just wondering.

I had a Cobra drive and it did the same thing. I assume it is normal and indicates that there are no leaks. I never had any lubrication issues with mine.

Yes mine did the same, your ok

Had King Cobra for seven years , also did it and never a problem.

Thanks for the reassurance!!
