DIY Guide: The “elephant hose CCV (catch-can) mod”

thirty3 · 31-05-2008, 22:54

I have had this mod on a 06 golf pd since noveber. But catch the vapour in a can and re-route the air back to the air intake pipe.

I took is off today and got about a cup of water from it...I was gobsmacked by the amount in the small time frame.

Lofty86 · 06-06-2008, 23:04

Have done it to my Furby now, and run it for a tank.

Venting like an elephant turns out to be a top cheap mod.
Better mpg (in the uk, about 16-19c and dryish).
I havent got a catch tank, and have managed to get an almost oem look!
Will post pic tomorrow.
HTH, Dave.

Been running mine for quite a long time now. No obvious effects, but I'm

that no re-circ is going on. Nice clean air going in all the time.

Do you think this mod stops the egr clogging (because thats the sludge build up soot exhaust and water vapour from crankcase). Or do you think it just reduces the build up.

Basil · 09-06-2008, 16:17

Having scraped the goo out of the intake manifold myself - it's really nasty thick sticky tar-like stuff being formed in there. It seems you need both components (carbon + oil) to clog things up.
Dry carbon soot shouldn't stick as badly and would burn off pretty easily I'd imagine.

Yeah thats my thoery as well.....

I asked before does anyone know if venting the crankcase with or without a catch can is an MOT failure.

This way your not venting to atmostphere and the oil deposits being heavier than air collect in the bottom of the tank which can be emptiied periodically.

Ive just thought of another problem with doing this...

If you dont empty it, your engine is going to be sucking hard on liquid oil/water!! never good!
Not worth the risk. Ive just let mine vent to air.
Havent seen oil in the yard yet either, so thats never bad.

Lummox · 21-06-2008, 20:51

Very true, but how hard it it to empty it, do it when you check your oil.

Lofty86 · 22-06-2008, 13:03

I know what your saying, but hydrolic locking you car isnt worth it.

Just let it vent to air i would. (and have).

big_dave · 01-07-2008, 19:51

Anyone have a part number for the breather hose? I'm going to try this mod shorty and want a backup just in case

Lofty86 · 01-07-2008, 21:03

Oooer. Not sure of the number, but you might be able to get it off without cutting it or breaking it.
(is that wat you ment?)

On mine, the breather hose has been taken off complete, and replaced with said "rubber pipe" to make the elephant trunk.

Completely reversabe if you really want to (not that I ever will

)

Nor me actually.

big_dave · 02-07-2008, 13:43

Well my plan is to have everything ready made indoors then just go out, whip the old one off and stick the mod in place.

I've assigned my mechanic to find me one

Basil · 02-07-2008, 15:53

if anyone has any feedback after doing this mod- I'd appreciate hearing about it

Cheers
Bas

Shifty · 02-07-2008, 17:35

Did mine today. First impression, initail throotle response is better. I'll let you know what I think when I have drivin it more later

I used a copper end cap, some strong glue, and some washing machine waste pipe. More pikey than all of yours

ultra_joel88 · 02-07-2008, 18:09

does this cause a CEL light? what diameter pipe do you need and what length? what is the best pipe to use?

devonutopia · 02-07-2008, 18:43

Elephant hose mod does not cause CEL.

You need pipe with the same i.d. as the breather pipe nipple on top of the cam cover - I would guesstimate circa 10-12mm, allowing for stretch. I used some pipe usually used for water. I think it took around 2 feet of pipe for me, maybe a bit more - enough to get down to the subframe anyway.

ultra_joel88 · 02-07-2008, 19:14

so this would be ideal?
