Julia, Does my pf name do it for you aswell?

Seriously tho, if you want the noise, get a NEW twin piston dump valve. Personally i cant stand the noise of bailey dump valves, they are SO common and they make a shitty tinny, metally sound imo. ATLEAST get some other make TWIN PISTON job.

If this dump valve caused problems then it's more than likely the wrong type or it is leaking, a bit of grease wont stop it leaking, i reckon the person who told you this thinks that it was sticking open/not closing fast enough.

The valve itself is POINTLESS, it does nothing for your car and im sure their are plenty other ways you can be turned on. . .
