charcoal canister required?

[deaf_rattle]

Looking at taking the charcoal canister out of my ma61.
I want to remove the hard line from the back of the car (tank to canister) as well.

Will this be a problem?

cheers

not really. boats dont have them at all. i think they're just there to allow an area for fuel vapours to collect and turn back to liquid before re entering the tank

that being said if you do remove it you will need to have a breather from your tank as they are usually sealed so with no area for the vapours to collect the tank could pressurise

[Mr Revhead]

yeah its an emissions thing

but don't tel the govt or they will make u need them!

You will need to keep the breather pipe, just put a small simota filter on it or plumb into your catch tank

interesting thing, my mate went into get a cert on his rb20det c33 yesterday, and got told he needed to have positive crank ventilation, which in short means the breathers (which currently go to a catch can) need to be plumbed into the intake, he suggested before the turbo.

said it was a new emissions thing for certs

whatever,

surely you could just loop them back up to each other (not good i know) but he cant not certify that surely?

Also, any cars certed some time next year or onwards will be required to have a cat converter fitted....

any info on that?

It's on the low volume vehicle certification website, cant find it just now.

Technically I think I also recall reading somewhere that you do need a charcoal cannister for either cert, or wof, or something. technically

Most "WOF Inspectors" would not even know what a charcoal canister is

read Section 2.5(1)

Suggests to me you'll only need to fit cats if you're undergoing an engine conversion using a modern engine.

I didn't realise they put jokes into the standards:

Positive crankcase ventilation

means a system which re-directs crankcase blow-by to the intake manifold and back to the engine, where it is re-burned in the cylinders as part of the fuel/air mixture. This cuts emission pollution and increases fuel economy because partially or un-burned fuel in the blow-by is consumed the second time around, in addition to keeping the blow-by and water vapour from fouling the oil in the crankcase, thus reducing the formation of engine sludge. Positive crankcase ventilation is also an essential aid against internal engine pressurisation and subsequent oil leaks - which is particularly handy if your engine was manufactured in England.

sweet, just gotta make sure my supra is all certed before may 2010.
