Changed the exhaust header and after starting up I have this sound that is coming from the bottom of the oil pan.

I have changed the exhaust header 4 times and am pretty proficient in doing so. Nothing out of the ordinary when I did it this time.
At first I thought... flex plate. Checked the bolts and they are tight. Don't see any cracks either. I ran it with the cover off and the noise does not increase. I would think it would be louder with the flex plate inspection cover removed.
Stuck lifter? I ran some Seafoam in oil for 10 miles and changed oil and filter. No change.
Does it in P, N or D.
Does it when cold or hot.
I can't imagine that I dropped something in the intake port not knowing so when changing the exhaust manifold. I would think the noise would be very loud up top if this were the case. This sounds like it is coming directly below the oil drain plug.
Standing over the engine it is not that noisy as you can hear from the video. Go underneath and it is loud.
When I changed the oil today it was clean with no debris.
Any suggestions as to what this may be? Hoping it is not a piston skirt.:wow:
Thanks!
