Ive been searching but no luck, anyone know the part number for 20v st front main seal?
Is it the same as 16v 4ag?

Also known as Timing Cover Oil Seal...

16V listed as 15100C Part #90311-32001
20V listed as 15100C Part #90311-32018

Toyota Parts Suppliers advise...
Part #90311-32020 replaces:
90080-31014, 90311-32001, 90311-32002, 90311-32017, 90311-32018

So yes, as you might expect, same seal and used on a whole bunch of
other Toyotas also... 4AFE, 7AFE etc.

I can confirm that 90311-32020 is indeed correct

Thanks guys
