B&S 303447 Blowing oil!!

just started blowing really bad, has always had small (what i thought was leak). Dont know where oil is coming from just yet. Just cleaned it off and will try to see tomorrw. Checked compression and it is 115-120. I am blowing out the gromet at the bottom of oil dipstick about every 2-3 months. I pulled dipstick and started engine today and seemed to be alot of pressure there, my finger was pulsating up and down with the pressure waves. could this be bad rings being as the compression was good, or should i measure with dipstick out?

The pressure fluctuations at the dipstick tube are normal. You'll have to see where it's leaking from, post results, and go from there.
