Out of pandemic boredom I've been watching a lot of YouTube videos on engine teardowns. I noticed a lot of Hyundai engines seem to have pretty severe piston slap issues. When they remove the pistons the skirts on one side are horribly worn/scraped up and so is the cylinder bore. I know a lot of engines have piston slap and most folks seem to think it's not harmful as it goes away when the engine warms up. But on these Hyundai's it definitely looks to be harmful.
Does this level of cylinder/piston skirt wear come from owners letting the oil level go low? Or is it just the piston design and if so, what about the design is bad? I can see they have a very short skirt, but so do my Hondas I think... The tear down videos I've been seeing include both the 2.4 and 1.8 engines. I don't want to start a Hyundai hate thread, I've never owned one but I'm just curious about what I've been watching.
