How can this be right??
I have a 93 JGC 4.0L. The other day I was replacing my valve cover gasket. I cleaned everything meticulously. Then it came to bolting down the valve cover. I took out my torque wrench and then refered to my Haynes manual for torque specs. The books indicates torquing the valve cover bolts to 75 FT LBS. I thought that was quite a bit. Any ways I adjusted my torque wrench to 75 Ft LBS. I started bolting down each bolt gradually until they were fairly tight but not to 75 FT LBS yet. The bolts were in quite tight already and I felt weary tightening them up anymore. That is when I took out my thick original Jeep Factory Service manual. This book also said to torque to 75 FT LBS. So I hesitantly began tighteniing the bolts when suddenly one of the bolt heads snapped. I didnt even get it to 75 FT LBS. These bolts were all new...I purchased them when I purchased the gasket. Now I have a broken bolt I have to contend with. How can these manuals be right? Isn't 75 FT LBS way too much. Am I missing something here?
