I have put this assembly lube in every Toyota (and every other make for that matter) oil pump I have ever installed both at work and for my personal engines. It has a very low melting point and mixes right in to the oil with in minutes of starting the motor. if this is what you used you should not have any problems with it building oil pressure Todd
