1. Position a plastigage on top of the journals in the axial direction.

2. Install the main bearing cap. (See CYLINDER BLOCK ASSEMBLY (I) [WL-C, WE-C].)

3. Remove the main bearing cap. (See CYLINDER BLOCK DISASSEMBLY (III) [WL-C, WE-C].)

4. Measure the main journal oil clearance. If the clearance exceeds the maximum, replace the main bearing or grind the main journal and install the undersize bearings so that the specified oil clearance is obtained.
