boost leak only when cold

[coryf1233]

I can only hear a high pitched screech during boost when its cold, when it warms up at normal operating temp, the noise pretty much goes away..

any ideas.??

make yourself a boost leak tester. cost ya less than 10 bucks with supplies from home depot. only way to really pinpoint any leaks. and it makes sense that you would only get leaks when cold. things compress when cold, expand when hot. probably just a vacuum line somewhere.

I second that, I actually made a tester and hooked up a bike pump with a psi gauge, its a Biotch to pump to 20 psi but works haha.

I did a BLT and on my boost gauge(prosport) it doesnt show any psi..but on my buddies gauge it read fine..so im not really sure whats going on
