whatever's blocking access to it has to come off. i think an exhaust system crossover pipe has to come off. First step, get some pb blaster or some other rust solvent and soak every relevant bolt with it long before you start the job, repeatedly. Some may break off anyway but less likely if you soak them good first.
Definitely use a REAL gasket on the new pan, if available. Ignore the recommendation to use silicone sealant only, this is nothing more then a cost cutting measure from the factory and nowhere near as good as a real gasket. Use permatex brown sealer with the gasket also.
It is very helpful to position the gasket in place on the pan after applying the sealant to pan and engine - and then use sewing thread through several of the holes in the pan to hold the gasket in place to prevent it from shifting. then insert your bolts and get the bolts started but do not tighten yet - remove all the thread first and then tighten.
These bolts are not tightened very tight at all, the measurement is in the inch pounds. Use a 3/8" or even a 1/4" socket if you do not have a torque wrench that measures in inch pounds (i work with mechanics and i dont know anyone that does). Get them bolts "moderately firm" and then stop. You will see the edges of the gasket squeeze out some, let it do that a little bit and then tighten no further. They need only be tight enough not to work themselves loose, it is the gasket and sealant that will prevent the leakage NOT the tightness of the bolts
BE SURE to tighten in a staggered pattern, similar to how you tighten wheel lug nuts. That is, do not tighten one bolt, then the one next to it, and so on - if you do you might warp the pan. Instead tighten one, then tighten the one on the other side of the pan. Then go to a bolt 90 degrees away from the first two etc. i think you get the idea.
