This is how my buddy blew the engine on his insight. It was burning oil so long that it melted the spark plugs. He could have had it fixed for free but he didn’t know about it until that extension had ended.
I actually don’t know what was wrong with it because he never let me take a look for him. I offered to have an engine delivered to my house and me and another friend could have slapped a used engine in.
He was hellbent on buying a new car so he traded it in.
