:( just wondered what the black can bit does. The bit thats mounted at the rear of the engine (top left hand edge) It has 3 hose outlets top hose goes to manifold one goes lower down and one dissapears downwards somewhere. It will probly be obvious when I know but it aint clicked with me yet.

That is probably the charcoal canister.
It absorbs Petrol vapour from the tank and a valve lets it into the inlet under control of the ECU.

Never looked on a GTV, but the description is about right for one.

Its the crankcase breather seperator/catch can. Ideally it should be removed every so often and flsuhed out to remove all the crud that accumaltes

Well, undo hoses, remove and wash out the oil smeg that has accumalated (sp?) - with meths or petrol or degreaser. put back on.

The charcoal canister also captures vapour from the induction system. It's one of the wonderful 156 features that I wish my old Uno Turbo had - it's parked in the part-of-the-house garage, it's Ok when it hasn't been driven for a month or so, but within that time the fuel rail slowly evaporates into the air and into the house...

Good to know I can park my Spider indoors ;)

I removed mine and blanked off the tube but the fuel tank made some horrible bending noises when pressure was equalised. I was thinking of putting in a small relief valve... Did you do anything like this 916?

I kept the catch tank which is the black box on the right and took the vent from the carbon cannister and fitted it to it :)

The vent goes out the bottom left of the boot and the catch tank only has 1 port on the top so no chance to get it wrong :)

when we're talking charcoal and carbon cannisters do these items need replacing at some point or do you just clean them as suggested earlier.?

You don't clean them at all, you just leave them alone.

The cleaning mentioned earlier was for the oil seperator on the crankcase breather.
