My chamber is trying to suck oil in when I close the valve. It spits a couple drops in when i close it at full vacuum but if I leave it closed and the pump on it doesn't suck any more oil in and doesn't lose any vacuum. I have a 3cfm two stage pump and a 2.5 gal vac it pro chamber. Thanks ahead for any help
stop posting new threads fuck post all your questions in the BHO threads like I already told you, and the answer to your question.
If the valve was toast it would not hold vacuum while closed and unhooked from pump. Don't think its the valve. If you don't have something helpful go post on someone else's shit
if your valve is closed and oil is making it through than the seal is TOAST lol how else is oil getting through a closed ball valve?
