Need help with BOV

[m1tch]

Hey guys, I just got my Baileys BOV (thank you and I am just fitting it, unfortunatly when its all hooked up, intake blocked, BOV fitted and Vacuum line put in, the car starts but doesn\'t idle, I can keep it from stalling by keeping the throttle down a bit, but there is obviously something wrong.

The T piece in the intercooler pipework that the BOV is fitted to is metal, the Baileys BOV diameter goes snuggly over that, do you think that this joint is leaky meaning I should get some silicon hoseing on there? The OEM hosing from there to the OEM recirc valve is too small for the Baileys Is there anything else I am doing wrong?

Can you post a pic of what you\'ve done ??  and what do you mean by
 
""unfortunatly when its all hooked up, intake blocked,""

Post a pic up - then we can see what you mean

(deleted) Oops, sorry Just seen that it\'s 2nd gen, Doh!!

Ok will do!

[m1tch]

here you go

[grinder]

thats looks like it should be !

you might have leak where it meets the IC pipe

[SmbFD3S]

Does the Baileys valve open when it\'s idling or is it shut ??
 
I have one fitted on an FD but when idling it is venting... Would have thought yours should be the same otherwise it would be boosting the intake as when idling air should be entering just on vacuum if you get me

That looks correct - you need to check all the hoses are sealed

[m1tch]

I though there might have been a leak between the IC and the BOV, but I have just duct taped the BOV onto the top of the rubber pipe so that it didn\'t leak hmmm do you suggest I try and start the car with the vacuum pipe disconnected so that it doesn\'t let of anything on start up? Then i will know if its the BOV that needs adjusting, how am I able to do that though? this BOV has come off an FD RX7 already lol

that valve should be open on idle mine used to be open when the car was idling i dont think the seal where it meets the pipework is tight get a pce of silicon to join the valve to the pipework and clip both ends and check the vac pipe as that should be lifting the valve on idle
get a vac source that isnt shared u have a t pce there take the vac pipe from plenum to valve and dont share the source
on vac that valve will open either tha vac source is too weak because its shared or ur vac is really low either way if u rev the car that valve should open

[SmbFD3S]

If you disconnect the vacuum it wont open at all and you\'ll be in the same position...
 
Baileys BOV\'s are not adjustable... Have you checked the vacuum lines for leaks as this is where i would start tbh

[m1tch]

Hmm ok, well I mean when I put the recirc valve back in place it works fine again, so it must be a leak, im gonna go try and temporarily tape the BOV to the IC pipework just to see if it runs correctly, its a pretty tight fit, but yeah I guess its about the only place I can think it might leak!

What happens if you use the recirc valve, but leave the return end open - i.e. you are using it like a BOV - so plumbed in for the vac pipe, and in the turbo to intercooler pipe, but just with the other end open and your bung in the intake pipe - this will test if your bung is sealing the intake properly.
 
Once that test is done, you need to see if your losing air out of the turbo to intercooler pipe - if you connnect the BOV, but leave the vac hose unconnected, and block off the vac hose end that\'s lose - so you don\'t have a vac leak - you now have a BOV in the circuit, but it will not operate.  This will test if you have an air leak from the BOV or it\'s hoses.
 
Can you not use the stock hose that fed the recirc valve ? - it may take some getting on to the BOV, but should fit.
 
If the problem happens when you connect the VAC actuator line up to the BOV, then there is something wrong with the BOV.

ok I will try all those things lol the problem with the OEM pipe is that the ID of the pipe is the same as the BOV I think, so I can\'t get the OEM pipe over the lip on the BOV hmm I will try all those things in a bit when I have sorted something else thanks
