Stock DV in reverse?

[a4rings]

my gfb hybrid valve is leaking. for some reason the piston on the inside does not seat all the way to th ebottom of the valve so there is TINY opening where air escapes where the horn is connected to the side of the valve. So in the meantime i am going to put my stock dv back on and im not sure which way its supposed to go on. Should i put the side or bottom of the valve on the pipe connected to the intercooler pipes? thanks

The stock (diaphram) type of valve should always be installed with the side tube going to the IC pipe and the bottom is the return.

if installed backwards, wont it cause surging?

I'v heard of people installing valvs like the 710n backwards. i installed mine backwards earlier today(boost tube comming from intercooler piping into the bottom of the valve) and it seems to be working just fine. what kind of symptoms should i be seeing?

Audi installed then both ways, but it worked backwards at low stock boost. Problem is that they never last very long when installed like that because you are putting pressure on the bottom of the valve along with pressure on the top thru the vac line, this will cause the rubber diaphram to rip sooner then it would if installed the correct way. When you install it with the boost going into the side tube there is no pressure put onto the valve which means there is less stress on the diaphram. Only piston type of valves should be installed with the boost pressure against the bottom of the valve.
