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.

What’s the knocking noise coming from MY Suburban?

How can you fix a tappety engine? A pretty severe case here. Via YouTube channel Mesomorphman
