2010 Toyota bB oil seals: what they do and when to sort them out

Oil seals absolutely are used on the 2010 Toyota bB. Toyota’s own technical literature confirms this: the Toyota Electronic Parts Catalogue (EPC) for the QNC20/QNC21 bB lists front and rear crankshaft oil seals, camshaft/timing side seals, and transaxle drive shaft (output) oil seals. The Toyota Repair Manual for the 1NZ‑FE-powered bB also includes procedures titled along the lines of “Crankshaft Oil Seal Replacement” and “Drive Shaft Oil Seal Replacement” for the U‑series automatic/C‑series manual transaxles. In short, oil seals are relevant, present, and important on this model.

On a 2010 bB, oil seals keep engine and gearbox oil where it should be while rotating parts do their thing. The front crankshaft seal sits behind the crank pulley at the timing cover
