Hello all, I'm in the process of changing my valve cover gasket on a 7.3 IDI N/A in a cut away chassis (doghouse box)

Driver side is off but having issues removing passengers side...

I've undone the passenger motor mounts 2 x 19mm bolts and tried to jack engine but it's not lifting... is there anything else I need to undo? Do I need to hit the bolts through?

Engine mounts (passenger side)



Passenger valve cover no clearance
