Sorry for the multiple posts. I just need to get an answer before I leave work in an hour. Anyone know the inlet/outlet size for the OEM valve.

I'm hoping a universal valve with the same size inlet/outlet would work, any ideas?

Mrkrad

the tiptronic even has a 3 way valve you won't notice it till you break the nipple off. fortunately i haxored a Tee and a spare check valve.

I'd guess some are 3.5mm and some are large like 5mm but i'd have to go out and check. fortunately hose stretches i found 3/16" too small and 3/8" too big (sometimes on the 3/8").

Other sizes weren't in stock so i didn't bother. After i fix the evap line hose i'll post a 2 month opinion on the usp plastic kynar valves. I'll take them all off and verify they work then put them back on.

There's 2 of them pretty close, one with the small L hose, they both look to be the same. I need to replace the one that's a little lower and to the left when looking at the engine.

Which is the 3 way valve. I'd like to know in case I need to ever change it. I just changed the one to the left of the engine next to the airbox.

Mrkrad

on tiptronics right drivers rear you'll see a valve that has a tiny third nipple(lol)

Heh. See it - the third barb is to the back...thanks!
