Just found out my car has many vac leaks, all leaks are sorted bar 1, the passenger side turbo has a big leak according to my mechanic, he said that if you gradually floor it u will hear the leak, it is quite hard to hear as the exhausts are loud, its going in to be hooked up to a smoke leak detector to pinpoint the leak, I hope its not going to be to much trouble, looks like I will have to keep the boost right down till I get it sorted. Bloody car, does my head in sometimes.

how does a leak detector work then??
