Think I gotta have a look at the Stag tonight.

I'm aware the BOV outlet is plumbed back into the inlet system after the AFM, but somewhere along this path I've got a leak. I can hear it, although all the piping/rubbers are in place.

Might get the GF tonite to rev it and get it boosting so I can find the leak.

4 Qs tho:

Anyone had this problem before?

Obviously its not harming the engine?

Is there a better method for checking the leak?

How do I get the GF to clean my car while she's at it? :D

dont bother with your car running cause you may find a leak if your lucky but you may not.

grab a frezzer bag from the pantry, undo the hose clamp where your intake goes onto your AFM.

remove the afm and put the bag over the end of it and then reinstall as normal.

now remove the vacum line to your FPR or similar and stick compressed air in there. this will pressurise the whole intake system and alow you to pin point any leaks from the intake manifold right up to the afm.

leave the bag double thickness will hold about 1.5 bar.

evryone should do this now and then as you will find even the smallest of leaks.

cheers

you havent just whacked on a POD by any chance have you?

you may have a leak in your cooler pipes, usually around the hose clamp join bits...?

Yeah, recently fitted a HKS pod. So I must have a loose clamp weaker thant he BOV spring rate when i shut off the throttle?

It actually sounds like the BOV exiting the atmosphere even so faintly.

I got distracted fitting 18" mags tonite. I'll check the clamps first thing before work tomorrow.

Could be your BOV, happened to me once. It got stuck slightly open...

Coincidental that I hear it now that I fitted a pod filter!

Actually, first time I've ran a pod filter on a turboed car, so I wouldn't know.

In that case, are you sure your not just hearing the turbo spool up?

Under what conditions can you hear the noise? If it's under acceleration i would say that is the case, the turbos just spooling like it should.

Yeah those HKS pods are loud. My car sounds like it has a BOV but it's just got the stock bypass with an HKS pod.

The Mrs got pulled over a while back because the copper "heard the BOV go off". He had a look under the bonnet and conceeded that all was ok.

    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
    • Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.
    • @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
    • I started removing the tank a while back with the intent to give it a proper clean. Got to a bolt that I couldn't undo completely due to a diff being in the way, so just said f**k it and siphoned the gluggy old fuel out and called it a day. Looking it the tank it looks less corroded than the one in the pics for that billet hanger from Frenchy's anyway. Isn't it the fuel filters job to worry about this stuff? I scraped off most the crusty shit of the hanger but will give it another go before reinstall coz maybe the fuel and return pipes are also full of gunk  
    • Pretty sure it is a common fault. I believe this is the only part you need, but don't quote me as I don't have a V36.  I also believe it is a bit of a pain to change and the device needs to be encoded to the car once it is replaced, so may need someone with the right tools.
