    Maybe after the plug test, see if you tossed a cam follower.

    Seen this many times as well, usually the motor is pretty crazy, even at idle, when that is the case...

    Head gasket. Seems fine at idle but the increased cylinder pressures with boost push it.

    Which is yet another reason why I said to pull the plugs. Anytime an internal motor issue is suspected that is the first thing someone should do. Spark plugs can tell you a lot...

    I would think if it was a head gasket, the car would have other symptoms. Higher than normal temps, using coolant. Even if it was a small leak, it could still be checked by wanding the radiator at any emissions station. Ask me how I know...........
