i have a mojor air leak some where . i fellow SAU friend recons i should remove the hose(pcv) and block both holes on crackcase and rocker cover to see if this remedies my delema . any one blocked theirs off? - the sound is comming from their somewhere yet i cannot locate it . it could be possible that the one way valve in the pcv hose is ruined , any one had any leaks there or blocked theirs?

YUp my pcv valve seal also has a air leak, you can hear it start to whistle when the car is idling, hasnt caused any dramas yet tho, if you really want to block it off and do a quick job you could just cut the hose in half a put a bolt in each end to block it off.

But you might aswell get a catch can then remove the whole pcv setup and get an alloy bung made to fit inside the original pcv valve seal that goes in the cam cover, thats what i will be doing very soon.

thanks for reply . after the car has warmed up a bit - the loud wistling noise comes on . wont go away . im going to atempt this today - hopefully this will fix it , iv had this problem for a few months and still no luck . will post results in a few hours. thanks

results - i blocked off the pcv hose , yet to find when the car started it was bumpy as all hell . so i put it back together as per usual. i thought of spraying some wd40 around the hoses near there , and the wistling leak stopped and went to just an air wooshing sound , still cant find it .

i tried putting a hose and moving it aroun trying to listen where , its got me stuffed

can anybody help - this is soooo anooying , and its causing a slight rough idle now and then.

    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
