Method Of Using PLASTIGAGE

WARNING: This page is about a different car, the 2016 Infiniti QX50. However, it is still accessible from the selected car via links, so may be relevant.

Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.
Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil holes.
Install connecting rod bearings to connecting rod and connecting rod bearing cap, and tighten connecting rod bolts to the specified torque. Refer to DISASSEMBLY AND ASSEMBLY for the tightening procedure.
CAUTION:
Never rotate crankshaft.
Remove connecting rod bearing cap and bearings, and using the scale on the plastigage bag, measure the plastigage width.
