Advise on changing oil pan?

[Joseph_H]

I need to change my oil pan and gasket and also I will be adding a new oil pressure sender on my E420. I am wondering if you guys have any recommendations on what else to do while I am down there? Shall I use some sort of spray cleaner to clean engine parts after removing the pan? If so, what spray do you recommend using - something that doesn’t harm wires etc? I found some minor leaks around the pan and sending unit. I need to change the pan because it is bent. My sending unit is also acting up. Any advise from you pros out there would be appreciated.
