1996 1.6 16v engine noise

[Agk007]

I rebuilt this engine recently and I’ve got this squeaking noise I cannot pin down. It sounds like it’s coming from the head of the engine, but it’s hard to tell. To me it sounds like camshaft speed and not crank speed. Camshaft looks a little worn but not horrible. What do you guys think? It’s quiet when cold but as it warms up the noise becomes present. I linked a video on YouTube to let y’all hear the sound.
