hey guys quick question and yes i have been searching but can a s1 pcv interchangable with s2/ vise versa? I read that 20 and 26s wont work on 25 but got s2 and only found part number for s1 and i need one asap! lol

i assume it is faulty - completed boost leak and couldnt hold pressure noticed air coming from filter on right valve cover so unhooked hose from catch can to pcv and blocked the hose and was able to hold 10psi.. makes sense bad pcv right??

been a long day always appreciate comments and input

You actually need to run that VC nipple to the turbo intake (with a catch can in the middle) Cuz thats actually a Vacuum leak going on depending on blow by. plus it will help seal the rings better under boost

EDIt: what the Hell is your catch can connected to?

haha yeah thats a shitty pic but catch can is inline with the pcv valve. just basically replaced that small hose from pcv and put catch can inline where the hose was if it makes sense

if i remember correctly i used one from a KA or 300zx one of those where a screw on so not that one. and you can just get a new grommet from local auto parts store

Back from the dead..what is a good part # for a pcv valve replacement from advance or local part stores? Can't seem to find one. I don't want to run catch can. Thanks for the help.
