Still Having Problem With My Hks Bov

[andy95'R33GTR]

guys, how to check the vaccums of the bov if the vaccum is sufficient to pull the valves of the bov? how much pressure should the vaccum be?, i already check my vaccum lines, and i can feel the vaccum pressure when removing the hose, but i don't know if thats enough to open the valves because the valves won't open, i can only open the valves when i push the valves with something, i can feel i need to exert effect on the valves to open it, and i think is springs are heavy?? i have 2 sequence HKS bov install and i can't hear the "pshhhhhh" when changing gears...

please help, thnx

hav u tried driving the car, or have u just poked the bov with a stick? maybe the springs are too hard, but if they came with the bov they should vent at some point. how much boost are u running? maybe its a sign to put the plumb back stockers back on, and move on to actual modifications.

Agreed - put the stock ones back on.

[andy95'R33GTR]

the bov came with the car from japan, im jealous hearing some stock evo's here venting there bov valves with a loud sound, i tried reving it when the car is in neutral, and also tried it running, it should should open right? i need to open my bov now...il take a picture later...when i push the valves, i think the springn is really hard, im running .8 stock boost... i don't have the stock bov already...as the bov came with the car

So BUY a stock set of BOV's.

They are what, $150.

You could sell your HKS one for more than the stock ones cost to buy you know

[andy95'R33GTR]

I want to use this one.. aftermarket

disassemle begins...

are GT-R blow off valves always located in that spot?!

Spring looks a tad rusty.

You could always just do away with it and have sick doses

[mr 32]

i have the same set and never had a problem with them on stock boost

are there any spilts in the vac hose going to them?

dont forget to check the feed coming fromt he engine bay from under the plenum

there might be a chance they are rusted shut, give them a good clean dont use wd40 as it will eat the rubber gaskets

[andy95'R33GTR]

mr32 can you have a video on yours? how loud your blow off sound??? and also picture of your vacuum lines....i want to recheck everything, even how much i rev my engine...the bov won't open..

[mr 32]

the only vid online at the moment is on youtube seach sau nsw drag day mr 32.

these blow off valves are farken loud, you will here them when they open.

this is under the plenum you can see the line marked BOV it goes to a nipple next to the intercooler hose

you can just see the nipple here to the right of the inthercooler pipe opening

the other side joins the nipple and goes to the bovs just make sure you check the air filters for the bovs aswell

[andy95'R33GTR]

this is how my lines routed...is this correct?

mate i dont want to sound rude, but have u even driven the car? you wont get the shit noise your after by simply reving it in neutral. why do you need to open you bov now? if it REALLY worries you, take it to your mechanic

[andy95'R33GTR]

i trust myself than letting mechanics touch my car... , thats why i try to learn...

[Sheriff Wan]

yeah good job andy - trust yourself...

mechanics were put here just to get at your 33 gtr and its BOV's....

[andy95'R33GTR]

ok...cleaned the bov...,checked the vacuum lines, still no luck...tried to run the car, and i can hear is the whooooshhhh..., i think its only the wastegates... to be continued tomorrow
