    Yes, pushrod engines can and do use timing chains. some engines use gear drive . Some times people will change a chain drive system to use a belt. Belts are typically quieter and other perceived benefits of going to belt are controversial.

  • Which is better push rod or timing chain?

    Pushrods have “easier maintenance” as there is no maintenance on/for them. Timing / cam chains do often have an expected life duration when they should be replaced. There is still a cam chain to drive the camshaft on pushrod operated valves.
