Catch tank

[stainesy]

been looking at catch tanks on ebay.
what the benafit of a catch tank?

[dangerstevie]

The standard breather system recirculates the crankcase oil vapors into the air intake, this lowers the effective octane of the fuel and as we all know that is bad. However this setup is supposed to be better for the environment, ( don't know about you but i prefer power to helping the green party)
By fitting a catch tank you pass the crankcase vapors into the newly fitted catch can where they mostly condense and pool in the can, with the rest of the vapor being let out to atmosphere. Keeping the effective octane as high as possible and keeping everything cleaner and nicer.

Someone please correct me if i am wrong anywhere about this, i dont think i am but just in case i remembered the theory wrongly.

the white pipe is just left open under the gearbox, you still a smell of oil when sitting in traffic tho

[stainesy]

oh right so the pipe that normaly goes to the pipe between the air box and the turbo goes to the tank and another pipe coming out the tank to under the the car and thats it?

actuly that pipe that raps round the engine and goes to the air pipe just before the turbo. could that just be re directed down under the car and i blank off the hiole left in air pipe to turbo?

as the pipe on mine seems to short and is constantly pulling the rubber seal from the air pipe.

Is that a 'home made' reverse IC pipe?

Looks good either way!

Cheers for that, I might have to look into making one up

you want 19mm outlets on the tank, altho i've used 15mm outlets & just secured the pipe with a jubilee clip

[Volvostorm]

And remember to empty it once in a while!

Think ill get myself a catch tank instead of replacing the pcv.

Keep me posted stainsy how you do!

[stainesy]

LOL yeah the ones iv been looking at have a glass tube on the side to show how full it is.

Yep, all those replies sum it up nicely. Its a well worthwhile mod, although i have 1 question. The std breather connects to the little soleniod valve thing on the air intake, what is that valve, what does it do and what is the little vac pipe on it for??

And those RIP pipes are lovely. Where did you get the ally pipe and silicone joiners from???

its a little heater element, you don't need it. The small pipe is a breather for the vac tree

the stainless steel was from Custom Chrome in Nuneaton & got the joints from ebay

Which ones you looking at Stainsy?
