Default Any guesses on what this noise is?
This is a short video of a motor noise. I think it is a lifter. It comes and goes randomly. Sometimes it is there and some time it is not. It is more on the driver side of the motor. I will be taking heads off tomorrow. So any guesses?

So I pulled the heads and the cam. Everything looks ok. Cam has funny patters on base of the lobes. Lifters look perfict. Any ideas? Will upload pics when I get home.
