What does a failing head gasket sound like?

This loss of compression results in a rough running engine and a notable reduction in engine power. This sort of failure typically is accompanied by a sound like an exhaust leak.

Can a catalytic converter cause a knocking sound?

The noise is normal, and is created by engine pulses being amplified through the light-off converters. Do not replace the converters unless loose internal components are found. To reduce the noise, install a wrap kit (P/N 4L3Z-5E258-AC) on each of the light-off converters.
