i had to replace my oil pump and in doing so had to remove the exhaust and in the process. a bolt snapped in the manifold. so now i have to remove the manifold so i can drill and tap it. i cant get to it while in the car. any suggestions? i really dont want to break one off in the head...i have liquid wrench to spray it down. with and ya. i know to work it easy and all that. just any advice be good?? really dont even want to do this haha

 

far less likely that one will twist off in the head-
far less rust and heat there. Haven't looked at a '91,
but if some of the manifold bolts have a threaded end
in order to hold a bracket,dipstick tube,ETC.with a nut
as the older thirds have,those can be a bother....
Often as you try to remove the nut,the manifold bolt will also try to turn and bend/twist the attached
brackets...

 

I replaced both manifolds in my 1989 a couple fo months ago and the manifold bolts came out much easier than I expected. Hope for the same with yours.

 

ok well im half way through this project. the manifold bolts came out easy, i did soak them all night with liquid wrench thou. but apparently the power steering pump needs to come out cause there is one bracket attached to the exhaust manifold bolt. i have all the brackets unbolted from the motor and exhaust, and i dont see anymore. the 3 bolts behind the pump at the bracket, and then 2 bolts that attach the front bracket to the motor.. is there more? the pump wont budge.
