Oil pump

A cool fact about the oil pump, its not generally possible to replace in the car due to the oil pump relief valve being in the way. Also to get the oil pan off, you need to drop the subframe. When you drop the subframe, nothing supports the engine. Its a much easier job to take the motor out. A few people have changed them in the car. I have changed them in the car, but after the rig supporting the motor slipped one time, I will never do that again. 450 lbs of motor crashing down on my head is not how I want to die.

Oil pump drive

Late drive - Notice the wear on the flat spot. Compare the width here to the early drive shown below.


Early drive- Notice how much smaller it is than the late drive. Also notice the small shiny spot. That area is the only part that actually engages the pump.

Oil restrictor

Located in block. Limits the amount of oil that flows to the head. As the RB26 is solid lifter, it does not need as much oil up in the head as a hydraulic lifter RB25.
