What would cause a knocking noise when the engine is cold?
When the engine is cold, the appearance of detonation shocks, and hence the characteristic knock results in the use of fuel with lower octane (according to the manufacturer’s recommendations). A very common factor in the appearance of engine knocking is the use of a thinner cylinder head gasket, which causes an increase in the compression ratio.
What can cause a ticking noise from the engine?

- Lifters. An engine uses a series of lifters in order to provide the necessary force to mechanically open and close its valves.
