i'm rebuilding a 4cyl diesel out of a 2020. the old oil pump pick up strainer was damaged so i'm replacing it while i'm in there. dealer said part had been superseded by kit. the new parts replace the back of the oil pump, the strainer, and the oil supply tube to the oil gallery. it does not have a place for the small tube that feeds the lower idler gear. I've called the dealer and they've checked with technical assistance and weren't able to find any info. the service dept is going to look for bulletins. does anyone know if the oil tube for the idler is just not used? it would still be splash lubed. also the replacement block for the rear of the oil pump only has 3 bolt holes and not 4 . the parts drawing clearly shows 4 bolts holes.
