  • We are assuming you have your motor already removed and preferably on an engine stand as that will ease the process of checking your Toyota 2JZ Oil Pump.

    Remove the bolts under your lower oil pan to gently remove your upper aluminum 2JZ oil pan, and then remove the windage tray and the 10mm bolts that secure the windage tray.

  • Remove all the bolts that secure your oil pump in place and remove it, you will need a Toyota part or you can opt to use a impact driver to undo the screws that hold the 2JZ oil pump cover.

    You are done with the removal part of our How To Service Your 2JZ Oil Pump, now it’s on to measuring the play within the gears to ensure your 2JZ oil pump still works.

  • Now with the oil pump cover removed, use a feeler gauge to test the clearances in your 2JZ oil pump drive gears. You want to make sure they are not out of spec, so your 2JZ stays lubricated even under the highest of stresses.

Standard body clearance:
2JZ–GE – 0.100–0.175 mm (0.0039–0.0069 in.)
2JZ–GTE – 0.080–0.135 mm (0.0031–0.0053 in.)
Maximum body clearance:
2JZ–GE – 0.20 mm (0.0079 in.)
2JZ–GTE – 0.16 mm (0.0063 in.)
The 2JZ oil pump gears must clear a tolerance between these 2 ranges, if your 2JZ oil pump tolerances fall outside of these parameters you will need a new Toyota Oil Pump.
