I know its a PITA to get in and do it. But sometimes you can loosen all of the motor mounts and lift the engines weight with the crane and then re-tighten everything. More than likely the mounts were bolted on and then dropped in. There is a small amount it can be moved by loosening them all and re-positioning it before tightening it down... I'd venture to say by doing this you are going to make your oil filter clearance on the other side tighter....
