The Timing Chain drives the Camshaft.

Overview

  • We have seen a couple of single link timing chains on A12, which is probably the original A10 single row chain. Insist on the factory specified double-chain, like Nissan did for later A10s.
  • A rattle can be the trait of a stretched timing chain. Pinging/pinking has also often been mistaken for timing chain rattle


A-series engine has a short timing chain -- and with an automatic adjuster -- it rarely stretches or goes bad.

Compare to the loooooong chaing used in the Nissan KA24E engine:

  • KA24 often has timing chain problems
