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.

    • Hello Liam - HA - somewhere in flies - possibly I have an update, but I have been so busy, projects have taken a back seat to getting business back on track.  I will let you know the outcome, but I think I am going to go for the 8HP,  CHEERS.  ELVIS
    • Thanks Joshuaho96, yes - as someone else also suggested, the 8HP seems the 'smart choice' - HA - and ZERO to do with cost, but I am sure 8 speeds will be better than 6 speeds - HA - maybe.  I will purchase a new 8HP,  Thanks.  ELVIS.
    • Nobody said anything about getting a "...cheap Falcon box..."- it was JUST a question about a specific transmission.  And YOU may have a problem with not enough $ - HA - I do NOT - so please keep your comments like you are some financial guru to yourself.  BUT - much appreciated re the cost of a new 8HP and I twill probably be the way I go.  Thanks.  ELVIS.
    • Most people I know in the BMW world are swapping 6HPs for 8HPs. The 6HP has a big issue with one of the clutch drum bushings wearing out shockingly early which leads to them going into limp mode going into 5th/6th gear as the oil pressure loss from the worn bushing causes clutch slip. Even with the adaptations in shifting the TCU can't bump line pressure enough to keep the clutches from slipping and burning. I've personally looked at a 335d with 6HP28 with one owner and ~90k miles on it and the transmission adaptations were way out of spec and even though it nominally drove ok I'm confident it would have needed a full rebuild sooner than later. Other than that they're fine, but the 8HP doesn't really have weird issues like this to my knowledge and they're in everything these days so pulling them out of crashed cars isn't too hard.
    • There is an ABS pump and a few solenoids. You could trigger the front/rear solenoids with a pressure bleeder attached with a Consult 2.
