Boost leak???
 

Where to look for a boost leak and how do I see it?If can with some pictures please.

it can be a whole bunch of different problems,

im having problems with my front mount at the minute

hey man
 

i dont know if this will work but when you have a vacuum leak on a engine you spray starter fluid on the vacuum lines and it will bring the idle up or down try spraying the intercooler pipeing and holesis .. were you spray it and it does work then thats were your leak is ... this could be lots of outher thing man not just a intercooler leak ... so what is your supra doing so we can help u

Starter fluid or propane or brake cleaner are not reliable for testing ffor boost leaks. These methods require strong vacuum; Boost leaks however may cause no boost leak as they may only be leaking at 100kPa/s where your engine's vacuum at idle is only around 15kPa/s. To really test for leaks you need to pressure test the system.

Connect one of these and then pump up to 5 to 10 psi higher than you're normal boost level. If the pressure doesn't hold try putting a second one of these (without the nipple) in the other end of the piping to plug the throttle body side. So, plug with nipple on the turbo input and solid plug on the throttle body side. Then hose everything down with heavily soapy water and watch for bubbles. If you see none and the pressure's staying try another 5psi and you're good.
