8. Remove the Plastigage® material. Repeat the
test for each connecting rod bearing.

Connecting Rod Side Clearance

Figure 320 Measuring connecting rod side
clearance
Place a feeler gauge between the connecting rod and
crankshaft journal. This is the connecting rod side

If there is too little side clearance, the connecting
rod may be damaged or the bearing may be out
of position. If there is too much clearance, the
