What kind of engine oil do you use?

The 4agze oil pump is the same in the smallport 4age and the ae101 20V 4age.
ae111 blacktop pump is also the same by gears inside, but the cambelt tensioner is different.

I think you should check your connecting rod bearings and oil pump (especially the pressure relief valve)

If you have the original toyota oil cooler setup you should check the oil pressure relief valve inside aswell.
