Agreed. This subtle off beat metallic tapping sound is caused by lifters and can occur on a warm engine. Definitely not caused by the chain tensioner.

Well I have been wondering if the stiffer springs were causing some lifter noise, I think someone here dismissed that early on though. It does get louder than that.
