Something to think about....our manual says to use seal packing to make the gasket. And I believe the part no. they have listed has since been replaced by what is in the photo below. This is based on what I've been told by some off-road guys and the one parts guy at my local stealership.
It just so happens I'm getting ready to put my oil pan back on my 92' pickup (that's whats in the photo below). On another web site board I look for guidance on my yota pickup, the off-road guys swear by the toyota fipg (form in place gasket), they argue that it isn't the same as permatex black rtv or ultra grey rtv. That it is better than both and any aftermarket cork gasket. Thus, I spent $17 on the fipg stuff.
My own thought for these camry's (i've yet to do the oil pan) is if it's fairly easy to remove and replace, then I would be less hesitant to use black rtv. However, on these trucks it is a royal pain in the ass to get the pan on/off, so I am taking whatever measures are necessary to increase my chances of only having to do this once for a very long time!
According to the manual the camry pans have the same grooves as you see below off my 22RE....that is where the fipg, rtv, or whatever you choose to use goes in and then the inside of the screw holes. Look in the manual, they show you the pattern to make with the stuff.
