Hello, oil pan bolts? 100% do not need changed, can reuse the old set at 18 ft lbs torque, main bearings? well good question and the correct answer? they should be changed as torque on those is called torque to yield wheras you tighten them by degrees, What can happen is they stretch the threads with this typw of torquing, i am NOT saying you can not reuse, You should, that is the correct way but many times we have reused them with no issues, The trick and procedure here is to be sure you oil the threads of the bolts good before you put them in, here are the specs for them, I prefer to see new bolts but if cant find, you are ok using old, just be sure to look at threads to be sure smooth and no marks or signs of stretching
