    Q:
    What is the procedure for checking main and Rod Bearing clearances for the 1991 Oldsmobile Cutlass? Posted by Priscilla I.
    A:
    The procedure for checking main bearing clearances is as follows: 1. Install the main bearings and caps into the engine block, ensuring all oil, grime, and foreign materials are cleaned from the crankshaft and bearing surfaces. 2. Place a piece of Plastigage along each main bearing journal. 3. Install and tighten each main bearing cap according to specifications, ensuring the arrow on each cap faces the front of the engine. 4. After tightening, remove each bearing cap and measure the width of the flattened Plastigage strip using the scale provided on the envelope to determine bearing clearance.
