Intercooler Pressure Test For Leak

[GD51LA]

i want to know if my intercooler or pipes are leaking

im will make my own tool (probably been done b4) this is how

Rb26tt

i will disconnect both ends, the one from the throttle body and the other from the turbo side, then i will block both ends off (ill find something at bunnings) then pump 30 psi or so into the cooler and piping. i will have a psi gauge on one side with the readings of pressure. if pressuer drops off then obviosly theres a leak. i will find the leak with some sort of soap spray

what do you think? 30psi too much? im running standard boost..

i will post my findings with pictures

30 psi will lift the bov's off theor seat, TBH pump it up till it wont go higher(BOV's will open) Probably about 10 psi is plenty.

remove afms . put spaghetti cans where they are . pull off vac line to watse gate or anythign really . pump up to what ever boost pressure you run . squirt soapy water on everything in engine bay

Just dont expect it to hold pressure, as the air will go through the motor.

Cans are a good idea, I was about to turn up some bungs on the lathe.

Block the throttle end too and you should have a pretty good seal, block the bov with a bit of beer can to stop that leaking if you need to.
