spidermonkey Posted June 25, 2006 Share Posted June 25, 2006 lots of cars can have idle problems with atmo BOV's (my old integrale was one) i think there may have been prob's with the uk spec supe as well (not sure though) so i think the paper may have been used to close the BOV, mine makes a hell of a noise when i change or lift off Quote Link to comment Share on other sites More sharing options...

spidermonkey Posted June 25, 2006 Share Posted June 25, 2006 my old grale would stall if it didn't have a recirc bov on it and it ran rough as hell, i ended up putting a SAAB spec recirc on it and it was fine. My HKS one works fine on my supe though???? Quote Link to comment Share on other sites More sharing options...

afennell Posted June 25, 2006 Share Posted June 25, 2006 I dont understand it myself TBH. The paper was deffinately "pushed" in there by hand but why i do not know. Like i said the car seems to be running okish with it out. Bit of a scare at first but that seemed to have settled when i took it out. Will drive it to work tomorrow to test it properly and let you know how it goes. You could do me a massive favour if you want and just phone your garage and ask them if they remember doing it and if so then why. That would be cool if you could spare 5 mins. No probs mate, it's the least I can do. Very strange. Injectors are 650cc power enterprise. Quote Link to comment Share on other sites More sharing options...
letmeshowyou Posted June 26, 2006 Share Posted June 26, 2006 I cant see a leaky BOV causing this sort of problem - sounds more likely to me that you accidentally disturbed one of the hoses when you were taking it off - have you checked all of these? btw... is there an AFR guage in the car?

garetheves Posted June 26, 2006 Author Share Posted June 26, 2006 No there isnt im afraid. Ill go check all the hoses in a few mins but if not is there anything else you can thing of. The main reason i believe its the BOV is because, if im honest, i was a bit concerned about the turbo hesitating before i took the paper out, i just didnt feel that it was pulling like it should, then when i took the paper out it became even more noticeable.

letmeshowyou Posted June 26, 2006 Share Posted June 26, 2006 all I can say really is... don't be booting it until it's sorted. a fuel pressure regulator hose would be a favourite to me to be off... at first thoughts I figured the paper was in there to make the BOV quieter (not thinking that any more) though I have to agree with Adam that I'd be very surprised if the garage that did all of the work would have stuffed it full of paper to cure a leak problem!

Suprash Posted June 27, 2006 Share Posted June 27, 2006 My only guess to why someone would stuff that material stuff in there would be to collect the oil in the air when it passes. I know some people reporting getting quie a meessy area around the BOV due to it constantly expelling air in the same location... Quote Link to comment Share on other sites More sharing options...
garetheves Posted July 17, 2006 Author Share Posted July 17, 2006 Well after taking the paper out a few weeks ago now the BOV seemed to be working fine. Took her out for a spin the other day and it was still working fine, but on the return home i noticed the BOV get quieter and then stop working altogether. Check it out when i get home and there is load more of that same paper underneath the valve again. Exactly the same spot as last time, stuck below the valve. This is despite me taking the BOV apart last time to make sure there wasnt anything in there. I have no idea where it came from this time.

MarkTheBoy Posted July 18, 2006 Share Posted July 18, 2006 Its not something silly like sound proofing or something in the engine bay is it? I don't even know if there is any sound proofing in the engine bay so dont cane me if its a daft suggestion. Just thinking out loud. Quote Link to comment Share on other sites More sharing options...

Is there some kind of air/oil filter in the bov that might have worked its way up? Quote Link to comment Share on other sites More sharing options...
wkdtime Posted July 18, 2006 Share Posted July 18, 2006 Gareth, can you make out what sort of paper it is? Have you got pic of it situ in the BOV? Quote Link to comment Share on other sites More sharing options...
Ark Posted July 18, 2006 Share Posted July 18, 2006 Where is the BOV mounted? On the intercooler feed? There's zero chance of this being stuff sucked in off the road. Through an air filter and past the turbos without tangling up and stalling the turbo? No chance. Have you looked at your air filter? Maybe that is disintegrating. Also, have you completely removed the BOV? Maybe you can see stuff inside the boost hose. Quote Link to comment Share on other sites More sharing options...
Homer Posted July 18, 2006 Share Posted July 18, 2006 It looks like kitchen towel to me. Maybe someone stuffed that in one of the pipes to stop dirt getting in when working on the car, then forgot to remove it? If the BOV isn't closing properly I think you would have exactly the problems you descibe. Quote Link to comment Share on other sites More sharing options...
garetheves Posted July 18, 2006 Author Share Posted July 18, 2006 Gareth, can you make out what sort of paper it is? Have you got pic of it situ in the BOV? Yes they are on Page 1 of this thread mate. Didnt take any the second time round but it looked exactly the same. It does look like kitchen roll or the kind of tissue you get on large rolls in garages that kind of thing. Doesnt look like its come from the Air filter. Bov is mounted on the IC pipe just before the turbo so i cant understand why this paper has just turned up in the BOV and not in the turbo.

Matt Harwood Posted July 18, 2006 Share Posted July 18, 2006 I've had exactly the same in a HKS BOV on my car when I first bought it. I knew there was a problem as I'd had one previously on a different Supra. When I looked at it, I found exactly the same as you have. I assumed the previous keeper had tried cleaning it at first, until I found so much inside it. Has yours ever worked OK? Maybe it's something that gets trapped in there from new?

When i first picked the car up, the BOV wasnt working at all, then when i removed all the paper it worked fine for 2 weeks or so, then it re-appeared. Not taken it out for a spin since i removed the paper for the second time due to it being off the road while i fit my FMIC, so once im driving it again will see if it works.

Ark Posted July 19, 2006 Share Posted July 19, 2006 I'm amazed that all that paper came out of the BOV. Just think how much could have disappeared into the block Quote Link to comment Share on other sites More sharing options...
tango Posted July 24, 2006 Share Posted July 24, 2006 Hi guys, just wondering how tight PSI or pressure for to set the BOV on the car, when I put my on, it sound slugsh, so I put some more washer in to make it harder, my car is running about 14psi, is there a figure psi to set to or just as tight as possable? cheers Quote Link to comment Share on other sites More sharing options...
wkdtime Posted July 24, 2006 Share Posted July 24, 2006 I would reccomend to do it as tight as possible where no boost is leaking, your BOV should reccomend how many washers to use and what boost range it can be used for. Quote Link to comment Share on other sites More sharing options...
tango Posted July 24, 2006 Share Posted July 24, 2006 No it didnt mention anything, just saids use washer to adjust the strength, just incase if I have it very tight, well my car only running 14psi, if I have it tight- tight, will it be a chance that when release pedal its cant release preasure?

wkdtime Posted July 24, 2006 Share Posted July 24, 2006 Yup thats what i would have thought so, what BOV have you got most are already preset to take anything up tp 30 PSI+. Quote Link to comment Share on other sites More sharing options...
Ark Posted July 24, 2006 Share Posted July 24, 2006 No, HKS bovs use boost pressure hold them shut. It's a vacuum in the manifold that sucks the valve open, so in theory it will hold an indefinite boost pressure. Quote Link to comment Share on other sites More sharing options...
