missing link/check valve

[ervstr]

what is the hole in the side middle of the missing used for?do i plug it,leave it open or something suppose to connect to it.cuz when i got my car its already plugged with a screw/ while my friend told me its not suppsoe to be plugged.lmk

leave it open..air goes through it i believe

 

[ervstr]

does it breathe in air or push out air?cuz if it breathes in air do i need a little filter for it?

Are you talking about on top of the valve cover? If so, it's supossed to be unplugged.. I didn't think so eaither but it is. It looks weird, but leave it alone. No little filter or anything.

please post a picture of what your talking about because the hole i think your talking about is very very small...

Take that screw out. Leave it open. You might have to get a new missing link because from what I remember the hole is very very small and now it's too big

Also if you have a small filter coming off the nipple of the valve cover. Take it off. It'll hurt your boost

yeah i do have a little fited,do i just leave that nipple open?if i do just leave it open,its not gonna suck in anything right?i jsut put that filter cuz i though crap would get inside.

and ill take out the screw today and ill take i pic of the hole and lmk if i need a new one.btw will my car run better or will i feel a difference when the screw comes off?

 

[2slo4u]

well the hole was suppose to be left open, but since the hole is bigger now i dont know for sure whats going to happen..
i would recommend a new one though, or better yet..a tune

people still use missing link? Its 2010, just get a map sensor

im just saving up for a whole new b series motor.this motor seems to be running good right now.i dont wanna spend big amount of money on it,just trying to improve it a bit.

Nothing will get sucked in. I believe it pushes air out when idling and does nothing when revved

oic.no wonder it should be left open so air get out faster?at some point that nipple on the vc was plugged too..they like plugging everything.lol
and i tried removing the screw they put on the missing link but its stuck there.so ill try use my dads ryobi and see if it budges.

the hole in the missing link is to vent boost pressure so the map sensor dosent read it.

 

[ervstr]

so if the hole is plugged would it affect performance or affect anything in general?
would this be one of the causes why i have a stall when i go from vacuum to boost(considering my turbo not spooling yet)cuz when i daily drive my car and i need to accelerate to catch up with traffic if i push on the gas pedal (not in spool range yet) from vacuum-boost it kinda stall.or this is normal for boosted cars?

Your map sensor is reading too much air since the hole is plugged. Probably running very lean. Check your plugs for white tips
