This seems like the simplest of jobs ever, but it has turned into quite an ordeal. I am trying to replace the main seal on my 4.0L XJ, but I cant even get the damn oil pan off. The gasket has just seated itself so firmly on the block that I can't force the pan off. I am aware that if I pry to hard on the lip of the pan, I could deform it. So, I am trying to be conservative with the force I am applying. The pan just wont break loose, no matter how much I pry or tap it. I am really pissed at this point cause it is such a seemingly simple job. Anybody have any ideas?
