Swampy442 Posted June 20, 2012 Share Posted June 20, 2012 Its the PCV valve, basically a ball bearing in a tube, stops boost pressure entering the crank case. And you *did* a boost leak test. Quote Link to comment Share on other sites More sharing options...
Gpro Posted June 21, 2012 Author Share Posted June 21, 2012 ok thats fine i will ignore that then Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 21, 2012 Share Posted June 21, 2012 If its leaking it needs replacing. Quote Link to comment Share on other sites More sharing options...
ashbuster Posted June 21, 2012 Share Posted June 21, 2012 lol dont look like the pipe tho mate looks like the part that goes into the cover, as above fix it Quote Link to comment Share on other sites More sharing options...
Gpro Posted June 21, 2012 Author Share Posted June 21, 2012 lol dont look like the pipe tho mate looks like the part that goes into the cover, as above fix it So it is leaking then! i got the impression its fine its supposed to do that. Anyone know the part number or actual name for it so i can get a replacement? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 21, 2012 Share Posted June 21, 2012 Its leaking pressure into the crankcase, you dont want up to a bar of air into the oil system. Its calld a PCV or positive crankcase ventilation valve. Would deffo be worth changing the pipe as well Quote Link to comment Share on other sites More sharing options...

Gpro Posted June 21, 2012 Author Share Posted June 21, 2012 Would it be easier if i cap of the pipe that goes in to the intake manifold and put a small air filter/breather on it? Quote Link to comment Share on other sites More sharing options...
Gpro Posted June 21, 2012 Author Share Posted June 21, 2012 i mean would that work ok? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 21, 2012 Share Posted June 21, 2012 No reason why not but there's no need to, just buy a valve and pipe. Quote Link to comment Share on other sites More sharing options...
Gpro Posted June 21, 2012 Author Share Posted June 21, 2012 Am just thinking wouldnt it be cheaper? Am going to toyota tommorow and get some prices Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 21, 2012 Share Posted June 21, 2012 It will be cheap! Are you the sort of person to pay 100 quid for a pointless induction kit or bov, but won't pay 40 for a essentials like new engine breather parts? Quote Link to comment Share on other sites More sharing options...
Hoppy Posted June 22, 2012 Share Posted June 22, 2012 If you want cheaper mate, sell the Supra and get something cheaper!! A nice little City Rover perhaps Buy a replacement valve from MR T > Fit it > Job done Quote Link to comment Share on other sites More sharing options...

Hoppy Posted June 22, 2012 Share Posted June 22, 2012 It's different mate. If i remember correctly, it's a metal 90deg piece with no 1 way valve in it. Quote Link to comment Share on other sites More sharing options...

Hoppy Posted June 22, 2012 Share Posted June 22, 2012 Gpro, has your PCV been welded onto your cam covers or is your rubber seal ring just bubbled up from engine heat. It looks a bit dodgy TBH. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 22, 2012 Share Posted June 22, 2012 Be careful when removing the valve though, if the O ring is brittle it may break up and bits could fall in the cam cover. Quote Link to comment Share on other sites More sharing options...
