My 32 has twin blitz blow off valves, which are perhaps a lot more audible than I would like.. see, Adelaide is known as the defect state.. and I can't afford to refit the entire car back to standard if I get caught.

Q) how loud (if any noise) are the standard gtr blow off valves? considering I have twin pod filters.. it sounds pedantic, but the nazi cops love seeing imports to fill their duty quotas.. and if they hear any light 'swooof' they'll slap a sticker on my car for a full inspection. As unfortunately is the way here; your guilty till proven innocent. :)

If you want, check out the outstanding ‘regency experiences’ thread by Steve in the Adelaide section to see what we face.

The stock BOV's do make a fairly audible "chooooof" noise when fitted with pods. They are however perfectly legal as they do plumb back to the inlet. If the cop is being an ass, just try and confuse him by saying ltos of big words like "the pressure release valves are perfectly legal, they are recirculating back into the intake of the engine" etc. Most of the time (in ACT at least) they give you the benefit of the doubt.

Cheers,

Though if I fit the standard blow off valves back on (as my car is WAY too loud now) I've heard about issue's with them leaking. I'm currently running 1bar, and would like at some stage to run a tad more.. can you effectly prevent them from leaking when raising boost or even running what I am now?

Generally you will be fine unless you make a point of "venting" within hearing distance of a police officer/car.

Luckily, aftermarket bovs on a GTR are not visible in the engine bay, assuming of course that you have your aftermarket bovs fitted in the factory location.

Police normally have a go at you for what they can see. Out of site out of mind.

Theres cars making in excess of 500kw using the standard blow off valves, they are really good. However, you can occasionally get a dud one which does leak...

      What should I do next to hold the head on

      By Gareth87 · Posted

      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.

      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
