What's this air feed pipe do? Mines splitting!

[realnumber 1]

Hi all can anyone tell me what the L shaped pipe does coming from my air feed. Mine has started to come away where it joins the main feed. Also does anyone know how much a new one will be and what it's actually called?

Thanks

Its an oil breather pipe, bit of breather pipe in the right length should suffice?

Oil breather pipe, you could just take it off, block the hole and fit one of these instead.



Or replace the whole thing with a silicone pipe.

better of getting one of these to save faffing about http://www.k-tecracing.com/show_prod...d=2410&appid=2

Cheers for the reply. Unfortunately its splitting away at the joint with the main feed so I suppose I would need a new/2nd hand replacement for the big main pipe.
I think I'd rather do that than get one of those filter things you've put above to keep it looking neater. Appart from the slim chance of sucking in a bit of crap is there anything else that could happen if it came right off. I don't think it will mind...

Just seen the above. That's what I need but sod paying that for a bit of pipe lol. Will have to try and find one 2nd hand I think!

[DaveDreads]

Nothing could really go wrong if it came away totally,
as long as you blocked the hole off otherwise crap will get sucked into the engine.

Cool it can wait until a 2nd hand one pops up.
If anyone has one kicking about feel free to PM me.

Thanks

excuse to fit a catch tank too

excuse to fit a forge or samco replacement.

Which has what benefit?

Really don't see the point in paying £60+ or whatever to have a pipe in a fancy colour when the bonnet is shut all the time...

It catches oil vapours from emitted from the breather and lets then condense back into oil. Essentially stopping the engine breathing them in to burn them off and will keep the intake tract cleaner in the long run too however for a road car its not going to make THAT much differences truth be told

What exactly is an oil breather pipe for why would you want air in with the oil? Might be a dumb question but hey thought I would ask... Mine seems to have oil coming from that pipe on mine? :/

[Gandi69]

When an engine is running, it creatures pressure in the crank case. If you didnt let this out you'd be blowing oil seals and so on. Oil vapour will obviously get into the pressurized air as its all over the inside of the engine and its hot etc, so this is fed back into the engine to burnt off as thats the convenient way to get rid of the vapour, its also for emissions reasons too. Race cars run a catch tank as they dont want these vapours be burnt off as to get max performance but race regulations state you must have a catch can and not just a breather filter, so the oil is in a safe and secure tank without the possibility of leaking out say if the car rolls or is crashed etc. Hope that makes sense.

Muchos Gracias my friend much better so to have oil on the breather pipe is normal then? It's just condensed oil that's returned to its liquid form on the pipe?

[Gandi69]

Yep that sright. Obviously you dont want oil pumping out in vast amounts but a bit of oil is normal

[Chapster5]

Sweet I'll keep an eye on it then I dont think it's too much oil on it just a bit, just worried me as I am having oil problems at the moment
