whats' up with the iron ?

Well, that awful number is an improvement over the one before! Something was grinding away on the inside. A compression test showed that everything was within specs. All four cylinders were above 500 psi. A front crank seal had failed. Perhaps the Iron was from it grinding away on the crank.
