All Forge Bpv Owners

[laloosh]

As you know my car has been stuttering with the forge bpv on. i put the stocker back on and my problems all went away.

IF YOU VALVE ROTATES AROUND THE FLANGE, IT IS LEAKING!!!!
i called forge and he confirmed that it should not be rotating at all.

this is an easy fix. Take the valve off, turn it upside down, you will c a snap ring with two depressions in it. insert needle nose pliers into the depressions and rotate the ring clockwise as hard as you can untill the flange no longer budges.


BTW i called 3 poeple with this vavle....all of theirs were leaking, chances are yours is 2.


you welcome(headbang)

Thats funny, should have known this already laloosh. It shouldnt spin at all...

[laloosh]

u know i did find it a lil odd....but never though anything off it lol.

[knowledge007]

Nice kill by the way on that Mach...You got to love it.

[laloosh]

yea it was funny, the list of excuses was even better though.

[shucky]

laloosh, so that means all your issues are solved with your mbc and bcd that you were talking about? I know you were experimenting to find out what the problem was, so this was it? Or is it still weather related do you think?

nope it was the leaking forge bpv. i race my car about 5 time last night in 34 degree weather with the stock bpv and not one single issues.

[Sierra117]

Is it something that could just shake loose or was it a (no offence intended) just a poor install?

[laloosh]

mine came liek that, i just didnt know it would cause a problem. its noting to do with the install, its the valve itself.

[ill_eagle94]

How do I test this theory? When I replaced the spring, the only part that unscrewed and or rotated was the top portion.

[laloosh]

see if you could turn the whole valve on the flange. add some effort ans don't be afraid to break it. mine was real loose

[ill_eagle94]

I'm assuming the easiest way to do this is with it bolted onto the car?

[scooter3]

What do you consider loose? I tried to move mine and it only moved like a cm and stopped.

[blaggah]

So the problems you were having after installing your TBE were from this, or do you still attribute those to the gas you used?

[laloosh]

bpv related 100 percent

[tru-boost]

i had to muscle mine for it to move, so i dont think i had a leak. i did remove the valve and tighten it up just for good measure. i only got like 1/16" of a turn and it was as tight as i could get it. everyone should check this out for sure.

[laloosh]

makes no difference...my car stubbled with the forge on last night. I think im going to call for a new valve...i just might have a leaky one. Witht he stock valve the car runs great.

[tru-boost]

did you open it up and make sure all the o-rings are still in place ? there is one on the flange... one around the top of the threads where the lid screws on, and if you pull the piston out, i believe there are 2 rings on the piston. maybe one fell out or is torn ??

[laloosh]

i dunno, i never had the whole thing apart, but im getting sick of it. Patrcik at forge was very helpful and said he would replace it no problem. So im gonna give them a call alter on and get my new valve.

[ill_eagle94]

It won't take care of the issue. :) If it leaked, you would not hit fuel cut, you would just feel a dip in power. Besides, I thought you had a boost gauge?

[laloosh]

i do have a boost guage lol. I am installed the cpe standback as we speak. Maybe it will make it go away. If not stock bpv it is.

[itzl0l]

yes and no...if its leaking back into the recirc that runs back to the intake then there would just be a loss of power. But if the valve is leaking to atmosphere it could deff. cause other issues

[tru-boost]

a leak under vac. will pull in un metered air, causing a lean condition. a leak under boost will do just the opposite. there will be metered air leaking before it makes it into the maniflod. this will cause a rich condition. and considering how rich this car is already at WOT, it could very well cause an engine misfire, due to a flooded cylinder.

[laloosh]

im taking this valve off and sending it to forge. Even with the cpe base map its still doing it. Stocker runs fine.

Can you post any pictures of the problem then post a picture of it fixed? I can't picture any of this in my head. Are you talking about the part at the top where the recirc tube is attached? I know that part can spin if you push inwards on it since it compresses the spring, but what you're saying is that it's broken or not on correctly if you can move that top part while the BPV is screwed on as tightly as you can get it?

[laloosh]

not the top, the whole valve itself moves. You know the thing u screw onto your intercooler, thats the flange. The cylinder looking thing wtih the two hoses attached to it, one on top one bigger on out the side. Thats the valve that moves independent of the flange. Try turning it, and use some muscle

Thanks, I know exactly what you meant now. I'm gonna check that out tomorrow morning. I need to change my spring anyway. Ever since I got the ETS intercooler i've been getting fluttering in 3rd and 4th while using the blue spring. It only really happens between 2k and 3k rpms if I let off the throttle. Gonna try yellow with two shims and see if it still flutters.

[tru-boost]

valve flutter is nothing to worry about. comp. surge is bad though. most valves that are stiffer than stock will give a flutter with a low boost vent.

I thought when you hear a fluttering noise that it is comp surge. It sounds just like the fluttering from some of the comp surge videos on youtube, just doesn't last as long. It only makes about 2-3 flutters.

Could the cold weather have made it start fluttering? I could have sworn that during the summer when I first put the ETS intercooler on that it didn't flutter using the blue spring.

[tru-boost]

i cant tell you what you have by reading a post. i can tell you that nobody has reported any surge with the blue spring before. it is common to hear a fluttery sound from many bov's while venting a small amount of boost. it is the sound of the piston opening and closing because there is not enough boost built up to make a forcefull exit.

[ill_eagle94]

I tried to muscle the valve last night at the track after my first run. It definitely turned. I put the stocker on again. I'm wondering if I should send Forge an Email?

[tru-boost]

i dont know what that would do for you. i,m sure they are tight when they ship out. after going from hot-cold and getting shaken around they probably just loosen up a little. if it continues to loosen up, that would be a problem. i think if you tighten it up once, it should not be an issue any longer.

[Ryz]

One thing I found was that just turning it would not make it totally tight. I had to press it in hard and turn, kinda like when your opening perscription bottles.

[laloosh]

i ran at the track with this pos last night. 13.8 @ 103, put the stock one back on 13.4 @ 106. im calling forge and throwing this pos in the trash.

[shucky]

laloosh which TBE did you go with? CS downpipe, PG mid, and which exhaust?

[laloosh]

its a custom PG prototype one of kind tbe lol

[itzl0l]

so what did u end up do'n with the forge ?

[laloosh]

nothing yet, im waiting for my fuel pump to see if it helps.
