    The car is a 1995 SW-2. I removed the oil filler cap while the engine
    was idling, and pressurized exhaust gas was emitted through the
    opening. Oil filler cap contained emulsion, and white vapor has been
    coming from the tailpipe upon start-up, which btw has been sporadically
    difficult (acts like a flooded engine). What would cause the space
    under the valve cover to become pressurized by exhaust gas?

    Usually it is worn/bad piston rings for the pressure and water vapor
    is normal (depending on the amount of it) YOu could pressure check
    the cooling system and check for a bad head gasket or cracked head too
    but this would not likely pressurize crankcase and make sure PVC valve
    is working and not plugged up too.

    Blow-by past the piston rings?

    sounds like a blown head gasket

    Yeah - he wrote me in email. Said there's oil in his coolant too.
    Definately AT LEAST a bad head gasket - possibly even a crack in the
    cylinder head.
