Danza V Posted June 28, 2013 Share Posted June 28, 2013 Hi all. I got a polo with an aftermarket air filter. The crankcase breather didn't have anywhere to connect it to. So, the previous owner just left it open with nothing on the end.. Car runs fine and I've heard it's fine to do this. I've checked for vac lines to connect it to, but there's none..Also there's like a little valve thing on the end with a plug on it.. I'm curious as to what this is. I've spoken to a few others and they said they left it off but I'm unsure. It's still venting out the gases as I've just left it vent to atmosphere..Help is appreciated greatly..

AdamB Posted June 28, 2013 Share Posted June 28, 2013 Sounds like its just got a 1 way valve on it. Its fine to leave as it is. You can just plumb it to recirc back into the intake manifold if you wish. Quote Link to post Share on other sites
Danza V Posted June 28, 2013 Author Share Posted June 28, 2013 The only way to do this I'd by drilling into the intake pipe and fitting a joiner to it. The car will be as I me ironed above yeah? Just I know it will stink of oil and may leak a tad oil but there's nowhere to put it. People have said just bung a filter on it, but i said it will if anything, restrict the fliw and blow a hoke in tge boock..by the way cheers for the reply Quote Link to post Share on other sites
AdamB Posted June 28, 2013 Share Posted June 28, 2013 Hmm have you checked a manual for the car? There must be something to illustrate where it goes to? I can't imagine thats standard. Does it have another top end breather as well? Quote Link to post Share on other sites
Danza V Posted June 28, 2013 Author Share Posted June 28, 2013 (edited) No it doesn't mate.. Just a crankcase breather at back of block. I did hear trisk had a polo and he left it to atmosphere..It's not standard. It was connected to the old air box, but now that's gone an I haven shite cone filter. So, there isn't anywhere to put it.I'm sure other people have been here lol.. Edited June 28, 2013 by Danza V Quote Link to post Share on other sites
AdamB Posted June 28, 2013 Share Posted June 28, 2013 Ah I see, if you really wanted to you could drill a hole and put it back into the air pipe, but tbh thats more hassle than its worth and will most likely just cause problems. You'll be better off to either get another standard airbox or just leave it to vent, put a longer pipe on it and cable tie it down the engine bay near a wheel to get rid of any fumes.

Danza V Posted June 29, 2013 Author Share Posted June 29, 2013 That's what I did on one of my other cars. Not good for the environment but, hey ho! I suppose it's ok doing that by mot air boxes havea little filter element in them anyway to catch the oil so only fumes are re cycled? I mean if I drilled a hole I woul most likely just get oil in the engine... Quote Link to post Share on other sites
AdamB Posted June 29, 2013 Share Posted June 29, 2013 Yeah hence why people run catch cans because it contaminates the fuel as well and reduces its knock characteristics If you cable tie it out the way or something, am sure no questions will be asked at MOT time, providing it still passes the emissions.

Danza V Posted June 29, 2013 Author Share Posted June 29, 2013 (edited) It isn't going to cause harm if its like this then ?I mean I know oil might come out, not much, but some... Edited June 29, 2013 by Danza V Quote Link to post Share on other sites
AdamB Posted June 29, 2013 Share Posted June 29, 2013 You'll only be helping to kill the planet, but don't worry, theres enough car enthusiasts that do the same so your not alone Not much oil will come out, it will just be vapour. Quote Link to post Share on other sites
