You might have an exhaust leak; I understand this is common with the 2.7. Keep in mind the TSB is for the 4.0. Exhaust leaks can amplify engine noise.

If you are still having some fairly cold days, pop the hood before you start it and look for light steam once started, much like your breath while outside in the cold. That's a quick way to find an exhaust leak while it's cold out.

Mine does some ticking on startup, 5W30, outside, but is plugged in; hence starting with warmed oil.

The only other thing I can think of is to inspect your valve clearances. IIRC while reading, this engine is shimmed, not adjustable like the 22Rx's.
