is it okay to have those lines that would originally go to the carbon canister plugged off?

what is the bottom of the canister suppose to look like? anyone can take a pic of the bottom of a GSL-SE canister? is it the same as other yrs/models?
mine has an opening with something inside it that i can feel with my fingers.
if its not suppose to look like that, can i just use on from a FC?

i am asking cause my car didnt hold idle till i removed the canister and plugged the lines. just wondering if that is okay or not.

 

cannister is the same from 83-85, fc actually should work too. if the car doesnt idle without those lines plugged, maybe you should look at the purge solenoid

 

more info please
where and what is the purge solenoid?

 

The purge solenoid is near the top of the engine,its a little black plastic canister with 2-3 vacuum hoses coming off it.The PS is vital to keeping the crankcase vapors and charcoal canister vapors moving to prevent sludging of the engine and a possible fire hazard.
There is no good reason to remove either of them,neither are complicated or rob you of any horsepower.By eliminating either one,you disable the whole system.On most cars the PCV and Vapor Recovery System are two different devices,but on rotaries,Mazda decided to merge them together.The hoses on/near the oil filler tube and center engine plate are part of the plumbing for this system, which removes crankcase vapors from the engine and gasoline vapors from the fuel tank,and then feeds them into the engine for combustion.

 

still wondering what i am looking at the purge solenoid for?
how can i tell if its good/bad?

 

Never heard of one failing.
Usually they are either unhooked all together, or the hoses from the charcoal canister/engine crankcase/purge solenoid/intake manifold are altered or incorrectly plumbed.

Its a little complicated,but you have to get everything plumbed in right.

The best way to check the system is to follow the lines.First off theres a line coming from the gas tank to the charcoal canister.It comes up from the firewall,next to the fuel lines.From there is goes to the canister.Then theres another line going from the canister to the center engine plate,just at the base of the oil fill tube.This is where the fuel tank vapors mix with the engine vapors.Then theres another hose right next to that one which leads from the engine block to the plastic purge solenoid.From the solenoid,theres one more hose leading to the intake manifold.
This system is vital for keeping the fuel tank vapors clear and keeping the engine clean inside.If you disable any part of the system you will experience fuel smell from the tank(which is a fire hazard) and the engine will develop that sludgy muck in the oil fill tube(which is an engine longevity hazard).

The only moving/working part of this 2-in-1 system is the purge solenoid.The system as a whole is pretty reliable and rarely needs attention.To make sure its working you can test the solenoid for proper suction.Remove the large hose from the bottom of the purge solenoid(this is the hose that comes from the engine block near the oil fill tube).Place your finger over the nipple on the bottom of the purge solenoid and increase engine RPMs to 2000RPMs.If there is suction at the purge solenoid at 2000RPM,then its working correctly and the system should be evacuating the fuel tank and engine vapors normally,while you drive.....provided you keep the fuel tank,charcoal canister,engine block and purge solenoid properly plumbed together......

 

thanks i will have to check it out

still wondering if the charcoal canister is suppose to have an opening on the bottom?
i can feel something inside the canister with my finger, there is an about 1 inch circle hole that is there. i notice on FC canister there is a hose venting to the atmoshpere.

 

Yes,it should be open at the bottom.Theres usually a spongy filter in there that keeps dirt out.
The charcoal canister can be flooded with raw gas if you park on a steep incline or are in the habit of topping off the fuel tank to the brim.The hole in the bottom allows the raw fuel to drain out in these scenarios.

 

i am guessing if the purge solenoid is fautly, there will be no suction/vaccum?

 

At 2000 RPM,if there is no suction at the bottom of the purge solenoid,then it is faulty,clogged or not hooked up right.Since its a pretty simple thing,Im betting they can b e cleaned up with some carb cleaner if they get grundgy.Theres very little to go wrong with them.I imagine a good intake backfire might damage one.....
