The Proton X70 is equipped with a 1.5-liter turbocharged three-cylinder engine, which uses a timing chain rather than a timing belt. This means that there is no specific interval for replacing the timing chain, as it is designed to last the life of the engine.
However, the engine's timing can still be adjusted if necessary. The timing of the engine's camshaft(s) and crankshaft can affect the engine's performance and efficiency. If you suspect that the engine timing is off, it's best to have it checked and adjusted by a qualified mechanic.
Adjusting the timing of the engine requires special tools and knowledge, and attempting to do it yourself without the proper training can be dangerous and may cause further damage to the engine. Therefore, it's recommended to take your Proton X70 to a reputable mechanic or Proton service center to have any necessary engine timing adjustments made
