LPG: Silent Engine Killer? Kia Rio 1.2

If you want to know what I’m doing in the video, turn on the subtitles. What happened to the engine after 150,000 km on LPG? The customer didn’t want to scrap the car and decided to try to save it. How long will it take before the engine gets damaged again? What could have caused the damage, and is it reasonable to install an LPG system in such a small-displacement engine? ⚠️ This is not a professional repair, and the video is not intended as a tutorial.
