I've been searching for about a couple of hours now, and was just curious.... how common are cracked blocks for 5.9 magnums? The reason I ask this is I have in my basement, a 5.9 short block that was pulled out of my friend's father's truck. It was pulled because the oil pressure took a shit and it JUST started to scrub the main bearings. If it were just a regular short block I'd turf it and start over. But, It has forged pistons, rods and what looks to be a aftermarket crank. The block has also been align-honed and zero decked. So again, how common is it that these blocks crack? any and all input on the topic is greatly appreciated. Oh and the truck was blown(SC'd) at one time, for what that's worth.
