Blitz bov....
Iv'e just fitted my new Blitz bov and taken the car for a test run... All was fine until I came to a stop and the engine stalled. The bov is second hand and I was told today that they can be an @rse to set up... I'm no mechanic but realize this could be to over fueling?? When the car stalled you could smell fuel. Will the ECU adapt or will I have to fart around with the bov? If so how? Thanks
Steve.

scoobies genrally do run rich, and after a hard run, it will smell of fuel a little. Quite normal, I think. Don't know about Blitz BOV setup, but do a search on it. You'll probably find what you are looking for.

Don't worry they're not an '****' to setup..
Warm car up, lossen 10mm lock nut (one around the hex/allen bolt) on top of BOV, turn the hex bolt clockwise until the plunger of the BOV is shut on idle (turning the hex bolt puts more tension on the spring in the bov). Give it a rev and note how the bov closes on idle. Keep adjusting until it closes nicely as the engine falls to idle after a good rev, lock off the 10mm nut. Take for test drive, if it still stalls, adjust some more.
If you can't sort it by adjustment, then it's dirty inside (piston moves up and down inside the body of the BOV and after time muck can buil on the inside of the bov body slowing the pistons movement when it should be closing fast on vacum pull.
To sort this you'll need some circlip pliers..
remove BOV from mounting (2 hex/allen bolts), press piston with thumb and hold tight, remove circlip, gently let the piston come out of the BOV body (don't let go of it else you'll loose a couple of teeth, the spring is strong), once piston is out, clean dirty parts, lightly oil, then refit in reverse order. It can be a bit tricky getting the piston in, just make sure it is straight and DON'T force it otherwise it gets stuck, give it a bit of a twist and ease it in (oooer mrs).
