Charcoal Canister

[portaz]

Hi guys I did a search on this but the results are not really suited to my issue. I want to keep my canister button new engine has the hard vacuum lines removed that go around the back of the now installed engine, which leaves the vac and purge lines on the canister without anywhere to hook up to, I could run a line around the back of engine for vac but no idea on purge, is there an easier option?

I fairly sure the canister lines go around the front of engine behind the plate that goes behind the cam gears , the three that go around the back are water for turbos, wastegate line and factory bleed valve line

[GTSBoy]

One line (the purge line - the lower of the two on the button) goes up the back via the crossover pipe. The signal/vac line goes behind the timing cover to the front of the plenum.

Bugger it looks like I don't have that behind the timing cover either then could I pick up vacuum source from same place as boost controller? Eg intercooler passenger side? Anyway around the purge?

[portaz]

Just had a quick look I can get the tubes from sss but it means full timing belt and can gear removal to acheive it mmm have to think about that one

[GTSBoy]

Just run a rubber hose over there as discreetly as you can and save the big job for a time when the front has to come apart.

I just realised you were talking about an GTR and so where I say "crossover pipe" and "plenum", there would be a slightly different arrangement on a 26. I was talking about lesser RBs.

[portaz]

Sounds like what I was thinking of doing its a bit rough but achieves same purpose I guess

[XKLABA]

yeah on the 26 both lines run across the front, are you sure the steel lines aren't still there because they are attached the the plate behind the cam gears so unless they have been unbolted they should be there

getting to where the small hose attaches to manifold is easy the bigger of the two is not going to be fun as it under the plenum next to the BOV signal port

[portaz]

Yes the guy who had it before I'd say wasn't running a charcoal canister and he had stripped alot of those metal lines, I'm really undecided as to whether run two hoses cable tied to the water line already there or pull it all apart and start again, seems a shame those cause I was so clever and did all the belt tensions and had all accessories installed before I put engine in.

Seriously, just run them down under the radiator out of the way.

Thought I would just continue this thread rather than start another. What's the legalities about charcoal canisters, do you have to run them? Is there any advantage not running them besides less piping and a little extra room in the engine bay? I should be able to remove mine as long as I block the nipple on the intake? Not sure what to do about the kind that runs back under the car, presumably to the fuel tank?

[GTSBoy]

Absolutely required. Instant defect without. No real performance penalty associated with them. Keep.

How long can these charcoal canisters possibly last and be effective? The charcoal will eventually stop absorbing stuff.

[StevenCJR31]

i vaguely remember a nissan manual stating to replace them every two years

[GTSBoy]

Um.......they absorb vapour released from the tank when the car is not running......and they purge those vapours back out of the charcoal into the engine when it is running. Hence, the port on them labelled....purge.
