New Dephaser time?

[gex23]

I've noticed my engine sounds rather diesel like as of late, also the idle is afwul, lumpy (almost like its running on 3 cylinders), and would like some opinions on just how bad this engine sounds and if you think I need a dephaser or there are potentially more serious issues :

Sounds exactly like mine. They all run rough on idle so thats normal.

I'm currently trying to figure out if mine is the dephaser or a sticky lifter. ive been told to disconnect the dephaser solenoid and see what difference that makes but nobody can confirm what difference I'm looking for!!
