I am going to install new motor mounts. I see that breakage of the block can occur at the mount points, and that a preventative measure is reinforcement plates such as Stinky Fab sells.
My question is how often does block breakage happen? Was it a problem with stock street driven, well maintained XJ's? i.e.... well maintained meaning mounts replaced prior to wearing out, bolts kept at torque specification, etc... what about a four wheeling rig? one that is driven cautiously and not too fast off road? or is the block breakage issue mainly for XJ's that see really hard use, racing, jumping off dunes, and such. Or mainly an issue of the bolts working loose do to improper install, thus causing breakage?
I am trying to justify my expenses. Is risk of block breakage high for my type of use? My use being slow going offroad, getting over hard stuff, but carefully, and of course highway to get to the offroading sites.
I used to modify old Porsches, some stuff was only needed for the autocross crowd, frame stiffening and such, and would be a waste to install on an otherwise stockish car for street use, Even mild hotrodded street cars would rarely get cracks. But for autocrossing it is a must to have reinforcement..
How do the motor mount reinforcements rate in utility for offroad use, slow speed, Do unreinforced well maintained offroad, slow jeeps have many failures here?
note my jeep is lifted 5.5 inches 33 inch tires, locker, Atlas 4.1.
