2350 front structure gasket

[Chamberpains]

Cummins isx torque to the exhaust side(right). A crack on the left side is usually a sign that someone torqued and tortured the engine pretty hard to twist that side enough to break something. Or best case scenario, an engine mount came loose and allowed the engine to twist. But I'd go with the previous and assume it was beat pretty hard. I'd leave that one be. Plus the whole front of the truck and the engine has to come apart to do a gear case. Probably close to a 16-20 hr job in mostly labor cost.
