Light Knock When Hot and In Light Load Condition

Light knock hot may be caused by one or more of the following conditions:
^ Loose torque converter bolts (tighten the bolts)
^ Exhaust leak at the manifold (tighten the bolts, replace the gasket if necessary)
^ Excessive rod bearing clearance (replace the bearings as necessary)
^ Detonation or spark knock (See Powertrain Management)
