Brooke,
check the infamous michelin man hose, the one from the crossover pipe
to the inlet of the intercooler. This is the one that seems to collect
oil and fail most often.
Obviously a test of the boost system with compressed air will reveal
any leaks and is a wise next step.
If your michelin man hose is bad I have a good stock one I can send you
to get you by.
If you get Samcos don't forget to order the appropriate clamps, the
stock clamps wont work.
