Engine knocking and oil leak
I have a 2016 c7 z06 that has an oil leak. Approximately 3000 miles ago I had the front and rear main seals replaced at a Chevy dealership. The car is still leaking oil but when I took the car to another dealership they weren't able to find the source of the oil leak. They also said that they heard a knocking noise about halfway down in cylinder number 7. The knocking noise goes away after idling for a few minutes. I've attached a video of the knocking noise. Any words of wisdom or advice is appreciated.

I was wondering/thinking if they got the torque tube reinstalled correctly too. OP, how many miles on the car and is it an A8 or M7 - I can't tell from the bell housing.
I would think a catastrophic knock from the crank or a rod would result in a loss of oil pressure.
