Has an oil leak, front of the engine towards the bottom. It's not dripping but the area is caked with oil wetness and mud. UT vids led me to suspect crankshaft seal needs replaced. Problem is when I search for the part on RA, Amazon, AZ, etc. all are giving me different parts (as in the part itself, not just the part number). Heck I am so confused. Which is the correct part number? Should I also replace the camshaft seal? I will be replacing the radiator due to a leak, TStat, serp. belt, idler, tensioner. Thought with the rad out might as well take care of the oil leak.
 
I just fell into a trap which may have caught you also. I looked up the timing cover seal, but found out they gave me the aux shaft seal. So that may be why you are getting different seal numbers for a "timing cover seal".

Of course all the rubber gets old on all the seals, you might as well change them all while you are in there.
 
Looks like a Timken 2955.

It's probably that or the housing that it mounts in, unless it's the O ring for the oil pump that's behind the aux shaft.

I didn't see a timing belt and tensioner in your list but would be worth doing while there
