what is this guys?

[andymac]

i think this is some kind of valve. its the thing inline that runs from the brake booster to the intake manifold. what is it? in the pic its whitish..

[xwill112x]

your check valve. dont break it. dealer doesn't carry them anymore, AT ALL. VERY hard part to come by around here. ask me how i know.

[mattdk318i]

looks like its missing the cap too.

[andymac]

is it just called a check valve? what kind of check valve?

[xwill112x]

yes a "check valve"

be sure not to break it, the plastic will be brital from age and they cant be ordered from the dealer or any other parts vender. i ended up using a m10 check valve on my m42 because i couldnt find the right one.

[andymac]

well it broke...have to have it? what exackly does it do? 1 way circulation type thing?

[xwill112x]

if you dont have it, you dont have brakes. lol


just find one off of a m20 or m10 is your best bet (or a M42 if you can find one), or buy a genric one that may or may not work off the interwebz.

could that line not being hooked up cause my car to run for a minutes than stall?

[xwill112x]

possibly?
that line is under and the intake vaccum, so your car MIGHT run then cut off. if it did run, the idle would be rough, and i WOULD NOT drive it.

[andymac]

perfect. i just finsihed replaceing all the coolant and vaccum lines under the air plenum. i was very careful and took my time. i thought i missed something..and as i was finishing everything i broke that valve. heart breaking. thanks for the help. would any check valve work...there on lots of cars!

[xwill112x]

im not sure. i just went to a pick n pull and pocketed a m10 one because the inlet and outlet match the hose diameter.

let us know if you find one from another car that works. :)

[andymac]

if i grab a m10/m20 i noticed they dont have the blow off like mine. make a big difference?
