Mini R50 Engine Clicking

So my engine has been making this clicking noise since its been getting really cold in the mornings. It only happens on cold nights and only until the engine warms up. I have just gotten the oil changed and have it booked for service next week but the dealer already told me they didn't hear any noise. I suspect they had the car in the shop the night before keeping it warm.
Any ideas on what it could be?? Please comment.

@elgablo1 you're thinking of a second gen. that's a first gen.

@20RoyalSuperKing Might have had the wrong viscosity oil put in too

Does the car have high mileage, like 100k or more? Sounds like a sloppy push rod or valve rocker. Once the oil warms up the lubrication should reach the rod and the clicking would definitely diminish as the cars warms. It's not a bad injector or else it would make the noise constantly. I would try a pressurized oil system flush, not just run an oil system product through. That has resolved a similar issue I once had with an R50.

is the anti-freeze ok it should be a 50/50 mix the water could be freezing. you should get your dealer to check the anti-freeze
