Default 07 STI p0446 P0452 emission leak codes

Anyone have any recs for fixes before I do a smoke leak test? Both codes for small leaks (evap related) changed the gas cap have to put some miles on it to see if that did the trick

Assuming we are refering to a USDM Impreza neither the 06 or the 08 US service manuals list P0446 (P0442 and P0447 listed).
Have attached both 06 and 08 H4DOTC Engine Diagnostic sections
