buy a rebuild kit from forge
I'm trying to track down some boost issues so I tested my diverter valve. I understand that when testing the 007 you push the piston up and put your finger over the top nipple and then release your finger from the piston and it should hold an drop down when you let off. When I do this the piston comes about all the way down, probably about an 1/8" from its original position and it let of and it sets the rest of the way down. Is this correct or is it leaking?
