Charcoal canister removal
 

Hey guys, i still havent put my cusco oil catch can on, and im looking at placement right now. I wanna put it where the charcoal canister is but then im wondering what to do with the lines that run to the canister. I know where they go but wondering what can be done with them.

The first line is the bigger line, the one that comes from the tank i assume. and the second is the one that runs over the intake over to the temp sensor on the thermostat housing. Iv heard the temp sensor line can just be blocked off. But what should i do with the bigger line from the tank? Also is there another line under the canister i missed? If so what do i do with that?

I don't recommend taking the charcoal canister off, but its your car and you can do what you want. The only thing it will effect is gas mileage and emissions output.

The big metal line that is near the firewall is the fuel vapor feed from the tank, you must block this off if you remove the charcoal canister. The little vacuum line that goes to the BVSV can just be plugged off. The metal line that is at the bottom of the canister that goes into a hole in the body is a fresh air feed, nothing to block off there.

yea my egr is blocked off with block off plates already so no worries there. but isn't it recommended to just vent the feed from the tank? I mean on hot days that tank is likely to pressurize no? I'd assume the "evap" canister also serves this purpose aswell. I was told by another tech to just vent it towards the ground? what's ur opinion on that matter?

If you are worried about pressurizing the fuel tank, then vent it. But you will lose a significant amount of fuel through it evaporating. You'd be amazed at how much vapor comes out of that line when its not connected.

How about this for a solution: make some custom adaptors so that the big rubber line goes directly to the BVSV? Just an idea.

Don't remove it if you don't know what it does. And a catch can next to the turbo is a bad idea. You need it in the coolest spot of the engine bay.

A charcoal canister stores and purges the fuel vapor in the fuel tank. It's not a mandatory part, you can run your car without it but you will lose gas mileage and output more emissions.

Do whatever you want with it, I really don't pay too much attention to mundane car parts that really have no effect on how the car runs and drives. I spend most of my time and energy where it matters, like the head gasket, timing belt, ignition timing and the turbo......

Oh? and yet toyota decided it was a good spot to store FUEL? Take a look under that engine bay once, then tell me where else it would go. Cusco and greddy both make mkiii supra kits that braket right to the strut tower, which is even closer to the turbo. So honestly i think its pretty safe.

To be honest id really prefer to have a catch can than to have to clean out my intercooler because some oil got through and over time is now gumming up my shit. Its just a smart preventative thing to have. On any turbo car.

WOW...., you guys need to relax a bit.

It's getting heated in here.

haha. im chill man. Im @ work till 6:30am. Things frustrate me easily right now lol. damn 3rd shift.

Ok well i should have said it would be better (instead of need) to put it in a cooler spot in the engine bay. Simple science tells you that if the surrounding air is colder it'll allow more vapors to into the catch can as opposed to it being next to the turbo. You can mount the catch can pretty much anywhere if need be. Just because some companies make brackets for a certain spot doesn't mean that is the recommended place for it.
