Well today while going through the service manuals procedure for inspecting the oil pump i found myself short a depth micrometer to do the side clearance measurements. I wanted to know that things were in spec so after scratching my head for a few minutes i went for the plastigage. I laid 2 pieces on the outside of both rotors and assembled the pump and tightened the screws down. after i took it apart and inspected. The measurement came out to 0.0020" limit is 0.0047" Seems like a easy cheap way to measure the side clearance without a depth micrometer
