have checked the linked thread, what size silicone hoses do i need to replace this please, can see howe its done by looking at it?

could this cause a decrease if fuel economy as ive noticed this recently....

I done mine last week but replaced it with a standard seat one its £27 from dealers

If you want part number let me know mate.

I did find silicon ones on ebay to but they were part of a set and from Hong Kong.

you noticed a difference since fitting it.... gonna go down the silicone route, afaik its 19mm silicone hosing and a tpiece to match, looks straight forward enough?

 

[adam cupra 20vt]

I'd only had the car 2 days before I noticed it and I had it replaced at the same time as a full service and filter upgrade so I can't really say if it made a difference or not.

As far as I can see it looks fairly straight forward to do from looking at the other thread.

 

[james walker]

anyone know where i can get 19mm silicone from apart from net?

halfrauds only go upto 8mm!!!!

 

[adam cupra 20vt]

Do you have any marine fabrication or hydraulic companys locally?

Thats where I used to get mine from......there handy for making up turbo feed pipes to

 

[james walker]

not a bloody clue matey, ill check yell.com......

also anyone know what this will cause... i.e running rich, or lack of pressure etc

One of the bottom ones split on mine. You'll notice a big difference in throttle response when its fixed. If its been like that for a while, your cam cover and intake manifold willl be very dirty.

 

[james walker]

cam cover not filthy, well ive just cleaned it...

theres alot of gunk inside the hose.

was it the same hose that split on yours.

[adam cupra 20vt]

Thats more than good enough its only a oil breather pipe.

No, it was the right hand breather hose on the underside of the intake manifold, yours is the one on the top right. It would have the same effect on performance though.

 

[Cupra Ross]

Its worth getting the better hoses, especially if re-mapped. Remember that these hoses will be under the same amount of pressure as your boost hoses and they have to deal with corrosive crank-case gasses on top of this.

 

[adam cupra 20vt]

That stuff in the link is fine tho its rated to 6.5bar of pressure

I'd rather have a brass T piece, make sure you keep an eye on the plastic one.

I also usually buy my T pieces a mm or 2 bigger than the ID of the pipe

 

[james walker]

sorted the hose yesterday

for future info


i purchased 19mm red silicone piping from the bay

£14 for 1 metre, thats plenty

18-22mm jubilee clips £55p each

19mm t-piece from the bay £2


followed guide in the link above, easy as...

now car pulls better, job done

£55 ofr oem part made of chocolate, £20 quid replacement into silicon

great mod and would recommend users to do this, as the oem hose will break at some point.

cheers

Well done mate, could you post up a photo of how it looks in your engine bay? I think I'll have a go at this myself.

 

[james walker]

i would, it looks exactly the same as the link on the first post..... exept the hoses are red, and the tpiece blue

bit of a faff getting enough purchase on the lower hose connection, but everthing else ease, and took 20 mins

all i did seperate, was use jubilee clips to connect all hoses to tpiece to make sure they stayed on.


but for 20quid its a real worthwile mod, and makes the bay look prettier

 

[Cupra Ross]

Thanks mate, thats the next job on the list.

 

[james walker]

well worth it...

im thinking of uprating other hoses in the bay, considering how pap that oem one was..

whats the reccomendation on these and where from... forge etc.

already got tip from samco done
