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.

    • I bought an engine from a friend of a friend many years ago, it was sold to me as a RB25det Neo.    recently I started pulling it apart and noticed that the intake manifold was pretty different from others that I had seen on RB engines so did a bit of research and found that it was a non turbo manifold. So I’m sceptical now that it is a NEO DET and just thinking it’s a NEO DE (it does have a turbo strapped to it currently).    can you identify the engine model from the numbers on the block?
    • Yeah you can. Cable tie the gauge to a windscreen wiper, or run it into the car and hold it with one hand, or have the neighbour's kid run alongside and tell you what it says.
    • I've never understood why this bothers people. Surely you'd be looking at a T3 flanged Garrett style thing, rather than a TD? You're unlikely to push a +T hard enough to need that much fuel. If you're not starting with most of the things you need to do that (ie, the bloody ECU!), you're better off just going Haltech/Link. You wil hate life a lot less. No. Just no. Just turbo it as is.
    • Have you noticed if the squeak changes with temperature or after driving in the rain?
    • Ok I get you. But isn’t the butterfly intake a headache with the +T?  see this is my plan so far but please advise me into the right direction.  Nistune Ecu, 1000cc Bosch injectors, TD05 or TD06 Kinugawa turbo using stock rb25det exhuast manifold, walbro fuel pump unsure of model I think it’s 450/460, spitfire coils and sparks to suit and a R35 MAF sensor and boost sensor.    I was thinking maybe do a cheap eBay plenum $400-500 or try find a stock det neo intake. I think I’d port match it so it’s getting the full capacity but open to advice please.  Thanks
