Can see why you're asking, you've moved your fuel filter to that spot...
Yeah you should have put up one of your old pics or a more generic engine bay

I thought they had something to do with stopping the fuel vapours building up?

It's an emmissions thing, takes the fuel vapours and lets the engine suck and burn them off. If Mr Plod is observant and sees it's missing you can be defected.

In NZ it matters not a single bit. It's not a WOF or cert issue. Just block off the line going to the fuel tank, the vacuum line going to the throttlebody and remove the metal pipe which goes to the air filter housing. I found it easier to cut up the pipe close to where it goes behind the brake booster for easier removal without having to remove the booster. I've removed them on both of my coupes with zero issues.

what about bypassing the canister and running straight to the intake?,

would pluging/blocking it off stop or restrict circulation? :o

Crank case ventilation/recirculation system. Do not block it off. This will result in gasket leaks (sump, rocker cover) It also forces the oil so stop draining from your turbo because of the blow by pressure and may blow an oil seal in your turbo. I've seen this happen! As for performance, the blow by does effect A/F ratios this is why they don't recirculate it in race cars. It can bring on pre-ignition (detonation) if your car runs too lean. Run an aftermarket canister so the blow by can be expelled atmospherically through a filter.

I don't think you understand. He's not wanting to block off the oil catch can - he's wanting to remove the emissions evaporation canister.

No don't do that. The canister has charcoal in it which absorbs the vapour to an extent and ventilates through a valve back to the air filter housing. The valve is what is controlled by the vacuum source from the throttlebody. The vapour from the fuel tank in no way makes its way into the intake of the engine after the throttle plate (which could cause running on, or a source of a massive vacuum leak).

Sounds good. I will plug it up and it will remain in the rubbish bin for the time being.

:D thanks guys
