help with part number 1JZ

[#04]

On the stock 1jz twins hanging off of the stock recirculated blow off valve, there is a little plastic diaphragm thingy, about the diameter of a nickle $0.05... on a vac line.

not sure what it does, 1 way air valve?

^but mine is broken, during removal for polishing... I have misplaced it.

questions are;

does anyone have a stock set up that they would take a look at to provide me with the part number? (its written on the part) careful as it is likely brittle

I was told it is also found on the MR2 not sure which one though

^because I am guessing it is important...

what does this part do? -- I like to know these things, but am not a licensed mech or anything...
one of the last missing pieces...

thanks in advance.

Just be a 1 way valve, a LOT of Toyota's run them, quick trip to a junkyard should get you a handful for spare change.

same as the brake booster (different size though)? and flow is out of the BOV ?

good to know, as toyota canada wanted $76 CAD for it, same plastic garbage, not upgraded metal unit...

one-way check valves (Toyota part number 90917-10049, about $5 each from Jay Marks Toyota

^something like this will do if I want to avoid $76 CAD price?


its on the top of the motor so I have a couple weeks until I am in dire need...
