I have high end hearing loss so not sure if i hear the squealing or not but if an oil galley is blocked leading to the cam bearings i would think it might emit a squeaking sound, even if it was one cam bearing or maybe 2 or 3 it could still run.

I think because the idle is turned down to barely even running (maybe 500rpm) and the 30w oil is so thick that it's not gonna splash like a normal setup would. If I turn the idle up even to 750rpm which is about normal for my cam, it starts splashing and spitting oil all over the headers and smokes a lot. You could very well be right but I'm hoping not! lol I just think the noise is too sporadic and inconsistent to be a bearing or even a lifter. I can see good oil flow at each individual pushrod so my fingers are crossed.
