What causes a loud knocking noise in the engine?
Connecting rod knock noise increases in volume with engine speed and is at its loudest on deceleration. The following are causes of connecting rod bearing noise: Excessive bearing clearance. Worn crankshaft connecting rod journal. Thin, diluted or dirty oil and/or filter. Low oil pressure.
Why does my car make a loud noise when I change gear?
This noise is usually heard when you drive your car, change gear and accelerate. The sound seems as if something inside the engine is knocking hard against the engine.
