this afternoon i was just playing around with my bov and adjusted too loose and the cap flew off.. and a few pieces flew out.. spring and cap thingy.. luckily the bonnet was open and i picked the pieces up (spring, metal bottle cap thingy) and screwed them back in.. afterwards i've been experiencing a rough idle and it seems to want to stall.. am i missing a few pieces on my bov?? i've been told i might have a leaking bov.. how might i fix it? Thanks

btw this is on an sr20det 180sx

have you got the pieces around the wrong way, i did this to my bov aswell unscrewed it too much and it went everywere and I put it back the wrong way so the gold bit that moves up and down was up the wrong way

if thats not the cause have you tightened it enough? , and no your not missing anything

mine had BOV spring , BOV copper gold thing(botle cap) , the top and the bottom ,

failure to that you may have damaged/ bent your spring? does it look ****ed?

i eventually put my stock bOv back on becuase the aftermarket was shit

not sure if its the same on a 180 but the r33 stock bov is mint

give me a PM if its not it and ill try and figure it out by looking at mine for u/ le tme know how u faired

air travels up on bov's

INTAKE

as air reverts back out it forces the cap thing up via air pressure and lets it out as the spring counteracts , so if you have in fact inversed it (flipped it) then its letting out air without any resistance e.g if cap is at top spring at bottom

the more air it lets out the less is going back towards the turbo , i didnt really notice any difference between tightening it / loosesning it , i would tigten it on a scale of 1 - 100

1% being loose and the top blowing off

100% tight as can make it

on the line it was about 70% i found it the best

so tight just not super tight

seems to do both release air + make a nice noise tight noise not fluttery

thatway you know its releasing it in 1 go not little bitts (fluttery)

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
