Hey. I have an 06 Hyundai Tucson that was given to me and this night when I went out the engine was clacking I believe when cold. If I rev it up a bit to like 2k~3k the clacking was faster. When the engine eventually warmed up I couldn’t hear it anymore at a stop light.
Now I just want to make sure what’s up. The engine isn’t that old 220K KM (137K Miles).
I read it might be piston slam which is no cause to worry and shouldn’t damage anything?
