Damn Boost Leak...

[erald01]

Quick question which i am not really clear about...I know i have a boost leak somewhere but i can't see it visually like i have done most of the leaks. This time is big and i can't seem to find it, but my boost gauge at idle reads -18 to -20 is normal at idle correct? Is it possible to have something internal gona bad that could cause the leak, such as valve seals or so?

Boost leaks won't change your manifold vaccum at idle any, however they will change the way it runs. Have you checked for corrosin on the upper outlet of the intercooler? Thats a pretty common spot for boost leaks. Are you using a pressure tester?

My IC pipes are brand new and i ordered the gauge from boostnet so i can do the boost leak test. I just hope its not an internal problem thats all im worry about it?
