I think i've got a problem somewhere, because my stock BOV (plumb back) sounds like one of those loud aftermarket BOV that are vented into the atmosphere... is there maybe a air leak somewhere?

I supose it sounds cool and all,but its just too lound and brings attention from the wrong people (cops) :)

you must have a pod filter. the air from the stock bov goes back through a pipe and ends up right in front of the air flow meter, making it almost as audible as an atmospheric one. you could always go back to the stock airbox, as this will dampen the sound almost completely.

as for leaks, if you rev the car from the engine bay listen to where the noise is coming from, my guess is the pod.

hope that helps

LOL if you have no filter that's probably what you're hearing.

It's also possible if you're running massive boost that the BOV isn't up to the job of venting the air and you're infact hearing reverb.. but you'd have to be running plenty of boost.

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts
    • Bunnings would have just handed you your money back on that one!
    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
