Thoughts on this noise? 13b
So I picked up a 91 FC that had been sitting for a few years, after getting all the crap cleaned out and finally running I come to hear this noise. My thought after some poking around is the chain for the cas on the oil pump, thoughts? The noise is really only at idle, when free revving the noise goes away which makes me think its the slop in the chain at low rpms is the noise. P.S. the water pump/Alt was not hooked up for this short video.

Update, noise is gone after deleting OMP and adding premix. Thinking the front rotor housing wasn't getting any oil causing that noise(no Oil in/on the injector when I pulled it). Car thanked me with low oil pressure(installing aftermarket gauge to confirm) and the alternator bearing decided it was next.
