soo. ive had some oil in the chamber for about 5 days straight now. under full vacuum. I went to check it out and maybe try pulling on it a bit more because of the degassing. I always turn the pump on FIRST and THEN open the ball valve up. this time I did and the gauge dropped right down to like 19"... that was as much as the pump could handle!!! soo. is my 109$ pump all of a sudden worn out? or could it be the oil, which I recently changed....? weird, I worked fine 5 days ago, did nothing but sit outside in the nice temp, now it wont pull a decent vacuum.. wtf????
