i just got an fd and there is a fairly large boost leak. i was wondering if there were any common places, causes, ect... on the fd where this occurs so i could check those first.

 

check the lower and uper intercooler piping. my lower had a large crack in it.

 

There is a short rubber hose on the "Y" pipe to crossover pipe that will crack. You have to remove it and use your fingers to press on the inside to find it if it's failed (they usually look ok even when failed).

 

The guys at SIDEPEX replaced two of my stock intercooler hoses which I broke

 

1 of 150+ vacs lines came off, hint its the black one.
