It's been awhile since I've been to that part of the engine, but isn't there one to seal the lower timing cover (located between the harmonic balancer and the crankshaft timing gear) and then another one behind the crankshaft timing gear to seal it from the main bearings and the rest of the rotating assembly?

EDIT- NVM, I just looked at the TSRM and there isn't one between the harmonic and the gear

Default 2 crank seals

Thanks, Yeah I don't know but my lower timing cover has nothing to hold a font seal and it seems kinda like it would leave the timing cover open for contamination the way it is. I am wondering if something is missing on my lower timing cover. I am going to go to the dealer on Tuesday and see for sure. See you at work Kevin. Scott

Could it be the oil pump drive seal? Check out 11301C on this diagram.

Default 2 seals!

Hey that drawing looks like it slightly smaller and thick. I bet that is it. I should use it then. Thanks Jim! Scott

ooops just ran the part number came back as Crankshaft front oil seal 90080-31022. Strange it's a crank seal but does not fit nor go on my car that I can see. maybe it crosses over to the oil pump seal. I will have to check with the dealer. My oil pump seal appears to be fine though.
Updated!

OK Mystery solved. The extra seal in the Felpro pack is the oil pump seal. Not gonna replace it cause it is not leaking. Not Broke? Leave it alone! The guys at the Toyota dealership sold me an oil pump seal knowing I needed a crank seal go figure! Evidently the oil pump seal on our cars also fit other cars as the crank seal.....
