if i dont need the canister with the four vacuum lines coming out of it in the front of the car what does the engine use to run/how will it run without those lines and if i take it out do i just plug em off?i know you need the BOV,FPR t run but it seems to me there has to be somthing else but i dont want to hook up a bunch of lines if i dont have to i just want it to run as smooth as possible.so if any one could help me and maybe post some pics up of the lines and were they go maybe it would click for me and i would understand.thanks in advance.

Let me start off by asking if this is the first car you done this extent of work to. I'm not trying to slam you, just get a feel for your depth of knowledge about mechanicsSecond, the canister is a vacuum canister that is part of the emmisions system. The lines "fume" carrying lines that run to that canister, which is a charcoal canister.

okay as far as my mechanic skills go ive took heads off a mitsubishi 3000gt and redone everything and timed it but as far as this i get the concept of it,put it this way first will i need it to pass emissions and as far as engine swaps this is my first swap but let me ask you this go and look at the thread that says old tragedes bring new beginnings and can you tell me what is the canister with the clear lines coming form it.thanks

oh and how would i plug up the holes that run in to the bottoom off the canister?

If I remember correctly the clear lines you see are coming from an Oil Catch Can.

How about you do yourself a fav. and throw the canister away? Just put a air filter on the line taht goes back to the gas tank and call it a day.

I believe the lines you are refering to in that other thread are run to the oil cactch can. If you are swapping in an RB, unbolt the charcoal canister. Snip the rubber lines that run to it. Then throw it in the garbage. It will not change how the car runs.

I can understand if you are wanting to leave the canister alone so it looks like you have all of your emissions equipment hooked up. But, remember that the RB was never sold in the U.S. So, if your state has strict smog laws like Cali, good luck getting it to pass. You might want to check your local laws and see if it's even possible to pass your states smog tests with that engine in there.

That is one thing I love about Oklahoma. No smog testing. Hell they don't even have mandatory inspections anymore. I'm sure they'll eventually change the law. But, for now, they let you drive pretty much whatever you want with whatever motor you want.

I wasn't refering to wether or not it would pass the tail pipe test. I was refering to the visual inspection. Some, not all, states have laws similar to California. These laws prohibit certain engine/chasis combinations. Especially when the engine in question was never sold here or designed to pass/meet our emmisions standards.

If his state emissions laws are set up like that, it doesn't matter if it will pass the tail pipe sniffer. If it won't pass the visual, it'll never make it to the sniffer. I just thought it might be a good idea to check his local laws before he does a swap and finds out that he can't legally drive the car.

1st. Find out about you states emissions laws. If they won't smog it because of the engine swap, you'll basically have a car that's for "off road use only".

Go to your local inspection place and ask one of the people that knows the rules in your state.

After pulling mine out and throwing it out, I wish I still had it. Capping the fuel vapor line causes the fumes to build in the gas tank and forces them into the cabin. Took the cap off and now my garage smells like gas but the car not as much...

It isn't a performance issue to run one and it will keep your car from smelling like gasoline all the time.

The filter won't do anything but keep dust from getting into the fuel tank vapor pipe. The garage will still smell like gas.

If it's there, its easy to run. No, you dont have to use it, but it's a good idea to keep it so your engine bay doesn't have gas vapors lingering around. Or you could remove it and run a vaccum line off the fuel tank vent tube away from the car.
