Cold Weather Issue is Cold Weather

[Grogger42]

I'm dealing with a frustrating issue with my 2018 CX-5 and wondered if others had a solution. Love the vehicle, no issues in warm weather. However, once the temperature gets below 7C or 40 F. there is a loud ticking noise near the front passenger side of the engine. Once completely warm I can push the accelerator to the floor, clouds of carbon then the issue is resolved for a few days. I thought it might be a lazy lifter or injector issue- have used several of the high end additives to try to correct the problem- nothing works, The ticking returns, you have to completely warm up the engine, floor it to clear the carbon then good for a day or two before the ticking returns at start-up.

Any one else have that issue or could offer suggestions as to what might be the cold weather problem?

This definitely sounds like a serious problem.

What does "clouds of carbon" mean? Oil (blackish blue smoke), coolant (lighter colored steamy smoke) or do you mean like an ashy diesel-ey smoke?

Hmmm CD issue with adjustable lifters ?

Thanks for the reply! It's a brief emission of ashy diesel-ey smoke on initial flooring. Subsequent flooring gives off a bit more smoke, but less- by a 3rd or 4th flooring no carbon emitted.

Would the lifter stop ticking after warm up? Once the CX-5 gets warmed the ticking disappears and won't return for a few days until another cold start.
