Gfb Bov
Greetings fellas. I was just wondering if anyone knows how to take apart the GFB stealth fx BOV. I have it running in my car and sometimes when i push the car, it dont seem to vent at all. If it doesnt vent, do it mean that there is compressor surge going on? I figure that the piston mite need lubrication. Can anyone gimme some tips on how to go about doing this myself and what to use to clean off the parts and what kind of lubrication i can use on it again? Any advice would be appreciated. Thanks in advance guys.

get the right allen head wrench....i think it's a 3mm or 3.5mm. place a rag under the BOV so parts cannot fall into the engine bay.
step 1: pull the vacume line of the BOV
step 2: remove the four allens screws that hold the top on. as you get to the last screw, make sure you keep pressure on the top of the BOV or the spring inside will send it flying!!! and there are parts inside there that you could lose!!!
step 3: slowly remove the top and keep one hand under it. there is a long spring and a cap that sits between the spring and the top of the BOV. hold all this together and place it on the floor (things you don't want to fall from high belong on the floor)
step 4: pull the piston out of the BOV body. it's not hard to get out.....just get a few fingers in there and pull!!!!!
step 5: get a clean rag....spray with a silicone lubricant and wipe out the inside of the BOV body. make sure everything is clean.
step 6: spray the piston and wipe that off.
step 7: spray the spring and all other metal parts.
step 8: make sure there is a nice coating of lube on all parts before install.
step 9: place piston back in BOV body, then place spring/cap/top assembly back on top and get one screw started so it doesn't fall into your lap when you let go.
step 10: tighten all screws (use anti-sieze, these parts are tiny and fragile...plus they get kinda hot, you don't wanna have any problems getting them out later) don't tighten too much....very little torque needed!!!!
i found that i need to do this once a month during the winter....that BOV just drys out really fast. once the summer sets in i only have to lube it up every once in a while. you'll know when cause the BOV won't vent well when it gets dirty!
if you need anything else....just give a shout!!!!

yeah, any silicone based lube is fine......you don't want it too thick, and you don't want it too thin. but any kind will work pretty much. for some reason the GFB BOV just seems to dry out quickly. but other than that i think it's a great BOV for the subaru!
