Jim,

An exhaust leak under the hood is very distinguishable. You'll hear the air very clearly put-put-putting away from the side of the head. And in my case since the engine is running a tad rich you can clearly see black exhaust smoke blowing from the rear three cylinders at the gasket.

Think I'll just change the oil and drive it. If nothing else I've got Triple A Plus to tow it the rest of the way if it breaks down. Thanks guys!
