Timing Chain Replacement

[Mameluke]

Gettin ready to do it sometime this week, but im readin through the instructions of othe install from http://alldatapro.com, and it seems that i need to remove the oil pan. and the oil pan is a total ***** to remove, involving a lot of suspension work , and raising the engine up and wat not. is there any way to do the timing chain replacement with out all that noise?

btw i have a 91 240sx, with a 96 block and 91 components (intake/exhuast/distributor/etc)

i also read on 240sx.org on that guys ka24e install that he didnt remove the oil pan, just put something over it to prevent anything from falling in, but i dont know if i coud apply the same concept to the kade, any help is appreciated. thanks
