DIY Boost leak tester guide

[Henk80]

It doesn't matter what you choose as long as it can build up pressure to approxably 1 bar (don't now how many PSI that is)
And have a gauge to read the value.

I connected my tester at the first intercooler tube from the turbo.

Good write mate
vids explains all will have to give this a go on mine as i think mine has a leak some where

 

[jimbomiller]

Great writeup - think i'll try this!

well well well. all my bits arrived today to make my boost leak tester. so here is some pics of my
10 min effort

hi, what site did you order the pipe from? i'm having trouble finding the right size on the net.

 

[sambryant]

Everything but the pipe was ordered online. I struggled to get the pipe myself. So what I did, I went to my local pluming center, they sorced a 55mm joiner(outter diameter 60mm) and an end cap, which they kindly stuck of properly. Cost me £5.50
the total cost was around £10.
Just to add I bought a low pressure gauge, goes upto 2 bar which is perfect for us. Same store as the link rsmith used but different gauge.

oh fair enough that's cool, i'll order the bits online and go somewhere to get the pipe, cheers for the info,

and thanks rsmith for the guide, will be very usefull!

well at long last i managed to get round to using the boost leak tester on my car today. im so glad i did, i found two big leaks. they must have been there since i bought the car as i havnt notice any loss of performance.
anyway here is a pic of the pipes that are split(mine are not forge just standard) these are located under the inlet manifold.


on the tester i couldnt get above 0.4 bar unless i covered up these splits. so can anyone tell me, should i get better performance once i have changed these hoses?
also were can i buy them, the forge ones seem very steep.

Glad it worked for you mate, i had splits in these pipes to and the boost leak tester found them for me.

The OEM ones are not that much cheaper than the upgrated forge or Awesome GTI ones and you have to buy them in a set from SEAT not just the individual ones, i upgraded mine as the OEM ones would inevitably fail again.

robbie will i see any performance gains once these are replaced?
forgot to say. the boost tester works fantasic and its the best £10 i have spent

 

[LaurenW]

I could do with checking mine

 

[sambryant]

anyone????

 

[greesha]

Sambryant. Maybe you should consider fitting oil catch tank to get rid of those pipes under inlet manifold?

Where are you from ? ^^

EDIT: Im 100% sure you will notice performance gain as I did with mine

 

[sambryant]

greesha im from bristol. i want to fit a catch tank at some point. still unsure on how to fit them properly.

just follow this link. Im sure it will be very similiar in LCR. If I have done it then anybody can do it ^^.

Uh a bit far then ... but when I will be next time in Bristol i will kindly ask you for pressure test, oks?

 

[sambryant]

yep no probs, you can have a beer aswell if you like .im sure the catch tank will be easy once i get it in my hands, its picturing it, thats the hard bit

No gain, but there is performance lose to be had, they can cause boost lose depending on where the split is, poor idle and in my case oil was being lost from one of them.

There only £23 from awesome, you should really replace them and be done with it.

This guide is not applicible to the LCR and can be confusing, but there are guides on SCN for the LCR, have a search.

Anyone tried this on his/her Cupra 6L? Which hose did you use?

 

[leoncupra666]

im having problems trying to watch these videos can anybody tell me which hose to connect it to or even have a picture i have just made mine and really need to test it many thanks scott

The one coming from the charge pipe mate undo ur oil cap as well and pull ur dip stick out
