Any idea why this is not connected, and cleaning engine pipework help

[cainhead]

Hello,

 

Anyone know what the white circled pipe is meant to be connected to. I noticed it when changing all the vacuum pipes. The car was originally an n/a and I had UK TT put in. Runs ok but it worries me that after seeing pictures of other supra engined this is connected.

 

Also as you can see in the picture the engine seems to be oxidizing on the metal pipes. Any idea of best way to clean this up.

 

Cheers

I am sure that the pipe you are referring to, goes to the pressure tank

After a little investigation I think thats the charcoal canister. I found a technical thread by Ian C about the sequential system and initially it does say to the pressure tank, however two posts up someone has corrected it as being the charcoal canister. Looking at this in my engine I see one pipe runs to one side of the intake manifold and the other dissapears off round the back of the engine. Any idea of seeing where this come out

 

Cheers

That pipe used to go to the Charcoal canister, i know because I've just removed mine lol. But it should be blanked off properly with a blanking cap, cheap enough to buy from ebay.
