I would push for new engine. No partially rebuilt engine will ever be as good as factory new engine. Don't let them make this your problem.
23K miles, obviously there was something wrong to start with.
I have knock when cold and only have 9K but have had this issue since it had 5K. But no antifreeze smell.
One dealer said normal, second not normal but don't want to touch it since first dealer already replaced lifters at 3700 miles
