Narrative:

GPWS warning. Arriving pdx from the east, night IMC, pdx landing runway 28, cleared to 13000 ft. Leveled at 13000 ft and began to slow in anticipation of the pdx slam. Slowing through 250 KTS on the pdx 090 degree/040 degree radial 40 DME, GPWS issued terrain warning. Executed escape maneuver. First officer advised pdx approach as we climbed to 16000 ft. Completed remainder of arrival without incident. Subsequent telephone conversation with pdx approach revealed MVA for the mount hood area is 13000 ft and ATC showed no altdevs until the escape maneuver. DFDR data showed both engines had exceeded operating limits and would have to be changed.
