Default strange noise

On cold starts. My car makes a rattle noise like metal taping together. Listen closely and can hear a very slight tap. But when car is warm. And I have drove around for a while . It doesn't make the sound. Sounds like maybe lifter ??

What is the mileage? Do you know the maintenance history? Is it stock? Could be a lifter, lots have some sort of initial start up tap. Could be a cold piston knock also.

It's at 135,xxx but I've had it since it had about 50,000 miles on it. Oil changes always come on time. It's pretty much stock other than intake and exhaust work. Just making sure it's nothing serious

Cars are like old people: They make noises when starting up on cold mornings.
