• Q: How to measure Rod Bearing Clearance with Plastigage on 2008 Dodge Viper?

  A: To check the clearance in the connecting rod bearings, use Plastigage or an alternative. Try first to place the connecting rod you want to check at the bottom of its stroke and then clear the Plastigage surface, as Plastigage dissolves in oil. Cover the bearing shell across the width in the bearing cap with some Plastigage, moved approximately 6.35mm (1/4 inch) away from the oil hole and 6.35 mm (1/4 inch) toward the center, to check any areas you notice. Before installing the rod cap with Plastigage, rotate the crankshaft until the rod just begins climbing toward the top of the engine; do not tighten anything or move the crankshaft after this. After shifting up the Plastigage, remove the bearings cap. Then, use the scale on the packaging to compare the Plastigage width with the correct band which will tell you the clearance value in thousands of millimeters. Keep in mind that a difference in readings between the two ends means some tapering exists in the bearing. Always write down your readings, as Plastigage displays both inch and metric markings. Checking engine bearings usually requires a range of 0.025-0.076 mm (.001-.003 inch).
