Motor Mount Torque

[bmw5002]

So, I bought a new $50 right engine mount for my 91 rolla because the rubber in my old one was cracked. I went to put it in tonight, and followed these torque specs from my Hayes manual, which is the same information available on autozones free online info.

Right motor mount and through bolt-58 ft. lbs. (78 Nm).

Engine mounting RH-to-engine manual-nut-38 ft. lbs. (52 Nm)

Engine mounting RH-to-engine manual bolt-47 ft. lbs. (64 Nm)

Now that I look at it I actually torqued the RH-to-engine nut with the right motor mount and through bolt spec (58 ft lbs). I feel like such a dumbass. Both bolts snapped off in the nuts. SO the mount is cooked, because the bolts are actually welded onto the mount. $50 down the drain. I guess I should've taken it to 38 ft lbs?

I've made similar mistakes with the bolts in and near the water pump. The ones that hold the body of the pump together only need inch pounds and I snapped one off since I confused it with the reading for another bolt. Fortunately an extractor got the bolt shaft out.
