When should the timing chain of EA888 be replaced?

[Gollum]

For models equipped with EA888 engines before July 2012, the timing chain must be replaced after 60,000 kilometers. The relevant explanations are as follows: 1. Reason: After 60,000 kilometers, the engine's tensioner may become loose, leading to the risk of timing chain misalignment or even cylinder and valve damage. If there are symptoms such as oil loss, difficulty in starting, or sudden engine shutdown while driving, immediate replacement is necessary. 2. Precautions: During replacement, the tensioner 06H should be replaced with 06K, the timing chain should be replaced with a threaded type, and all four guides should be replaced. It is recommended to replace the entire set, including the tensioner, timing chain, balance shaft chain, plastic guides, and the lower side cover.
