you are correct. With the engine off, remove the air filter and take a look down through the throttle body. If you see any pooled oil, you have a blown plenum gasket.

my symptoms were rough idle, low power, bad mileage(9mpg), oil consumption(1 quart per tank of gas). I did not have a noticeable amount of smoke out the tail pipe.

I took some pics of my plenum repair and posed them here:

Good Luck,
