Does this sound like lifter noise or piston slap?

Have you ever put a real oil pressure gauge on this engine? It's not unheard of for a high mileage engine to have low enough oil pressure at idle to not properly supply the lifters with enough oil for them to work properly. You are going to have to ignore many things that happen with a engine with 200,000 miles on it.
