That ticking is half engine speed. Rotational noise is a lot faster jmo
I'm with ya But diesels don't tick, they rattle and knock. Going by his description not the vid.....That speed tick from the vid is usually an ex. leak. There is no reason the stock rockers would be causing the issue for a typical freshen up.
