[Supras] Timing belt replacement

[Bob]

I don't have any reason to pull the pump.  

The oil pump drive seal is most likely the problem

removing the oil pan to get to the oil pump while the engine is in the car 
is a PITA. if yer refering to the oil cam bearing, then not really if I 
remember correctly. Eitherway, full directions are in the TSRM to do the 
work.
