DIY Boost leak tester guide
- Thread starter rsmith
- Start date
will have to get onto the band wagon here and start to make one always worth knowing if you have leakage
Can anyone do this for me around the west midlands area? My tdi 150 seems to whistle more than normal, be nice to check. Can it even be done on a tdi?
Im really struggling to find anyone around my area that can supply me the pvc pipe and end cap. Been to various plumbing suppliers with no joy
Im 99% sure i have a leak but cant find it![[:@]](/forums/styles/seatcupra/oldforumsmileys/furious.gif "Furious [:@]")
I made one today using parts from http://www.pipecenter.co.uk/
However beware that their prices are high for small amounts and try to haggle down.
For instance the end cap was £7 on their screen but they can discount to about £1.80! I paid £7 for the gauge and visited a local tyre fitter and asked for a tyre valve.
I was very lucky to get 60mm High pressure pipe for nothing as they had it laying around it would have been £6 a metre with a minimum of 5 metres!!
I have about 2.5 metres left of pipe (same as original build design on page 1) so if anyone needs some then PM me and I can post you a piece if you paypal me the postage costs.
However it didn't work as I tried a electric tyre pump which I confirm are useless. I will get a foot pump tomorrow and try again.
I bought a halfords rapid tyre pump that pumps a flat tyre up in 3 minutes. This worked a treat, however there is quite a leak as the pressure goes down quickly. Looks like a new set of silicon hoses are in order!
make one all you need is high pressure 60mm tube with an endcap and some glue. Get a valve from your local tyre shop and then get a less than 4 minute to pump a flat tyre pump with a display and your done. Easy!

yep remove the oil cap just to be safe if testing right at the turbo but if at the intake pipe definitely otherwise youll pressurize the crank case and oil seals (cam, crank mains). youll also need to plug the crank vent nipple on the intake pipe.
You only need to pressurize to what your boosting...no need for more. Youll have some air bleeding it wont just hold indefinitely. About 1psi / second should be normal...
