i have a boost leak and i cant find it when it gets over 8 psi it squeals like a pig, could it be the intercooler?

Thats a strange one, at least you have a spare.

fab a leak test from some tube
Get a piece of tube same diameter. Drill hole put in a bolt on or push fit tyre valve and compress it to 15 psi and listen for leak, easy to do.
Can use dye or washing up liquid for double checkingif you've found leak
Just put it on a boost hose, use an old one cut it in half and put your new fabed pipe in the middle. Make sure it's in a convenient place
Always handy if you need to use again
I made a simple little gadget for a leak on the TDI
Cut a circular piece of MDF or similar the same size as the pipe onto the maf,
drill a hole in the new piece to take a tyre valve, (i cut one from an old inner tube)
clamp it into the hose using the original jew clip and blow some pressure in with any sort of pump (i used an airline) the leak will become very obvious very quickly
P.S din pocket on its way

i used 25mm MDF once i had tightened the clip up... would have taken more pressure than the rest of the system, and i didnt have to waste any spares
Also by putting it in at the start before the turbo the system would hold the pressure instead of just blowing past the turbo.....
