When I first start my car it is making a chattering sound like a lifter or valve chattering it is worse on cold mornings. I have checked the oil and it is good and always changed when needed to be. I am not sure what this could be.

You have correctly identified the noise. It is not harmful, just distracting. Carry on and remain calm.
