[s-cars] Valve cover leak causing boost drop?

[David Forgie]

Jim: As others have suggested, your crankcase ventilation system has a problem, Houston.  Most
likely the one-way valve but it could be other PCV system components as well.  The cam cover has
 a vent that allows vapours to be pulled out and into the engine for burning.

Follow the link to the live Engine Bay Device map below and then click on the Crankcase Ventilation
 label in the lower right corner for more detailed information including flow diagrams and Part no's.

^^All the labels in the Engine Bay Device Map are live links as well (for future reference)
