A112 ABARTH. Noisy tappets? or something worse?

The A112 Abarth is making some unhealthy noises. It sounds like a valve/tappet noise but I cant seem to make it go away by adjusting the valve clearances. So I open up the engine and takes the rocker assembly off and inspect it. CHECK OUT Jethro Bronners channel If you like engine/car restoration videos!    / jethrobronner   ‪@JethroBronner‬
