You will need to pull the engine out to get the oil pan off of this engine.


4 X 2

  1. Drain oil, then remove engine as described under ENGINE.
  2. Remove oil pan attaching bolts, nuts and reinforcements.
  3. Remove oil pan. Clean sealing surfaces on pan and block.
  4. Apply sealer No. 1052080 or equivalent to front cover-to-block joint and rear crankshaft oil seal retainer-to-block joint, extend sealer one inch in both on all four corners. Install pan gasket.
  5. Reverse procedure to install. Torque bolts and nuts to specification.

4 X 4



So this would be difficult if you have no way to lift the engine out. The oil pump is in the bottom of the engine under the oil pan.
