Mitsubishi ASX Diesel engine knocking

I own a 2013 Mitsubishi ASX with a diesel engine and 199300 km on the odometer. I've noticed a strange noise from the engine, specifically a ticking sound that's audible when the engine is warm. I had the injectors reconditioned, but the problem persists. What could be causing this noise and what solutions would you recommend?

Summary of the thread

A 2013 Mitsubishi ASX with a diesel engine is experiencing a ticking noise when the engine is warm, despite having the injectors reconditioned. The noise could be caused by incorrect valve clearance. It is recommended to check and adjust the valve clearance, preferably by a professional mechanic, to address the issue.

Start by checking the valve clearance, as incorrect clearance can cause a ticking noise when the engine is warm. If you're not comfortable doing this yourself, it's best to have a professional mechanic inspect it. Let me know how it goes or if you have any further questions!

At idle, nothing can be heard; only under load, after 30-40km, does it start to tick.

Since the ticking noise occurs under load and after the engine has warmed up, it might be related to the engine's oil system. Check the oil level and condition to ensure it's not low or degraded. Old or low oil can cause insufficient lubrication, leading to ticking noises. If the oil level and condition are fine, consider having the oil pressure checked. Let me know if this helps or if you have any further questions!
