Need help with codes and smoke

hi lads, after taking the jag to a regular mantainance service (oil change, oil filter, two oil hoses replaced and engine wash) the car began smoking white, very dense white smoke, only for about 10 seconds after startup in the morning. I’m also getting the codes “too lean bank 1 and 2). The mechanic says it might be coolant leaking into the cylinder through a valve.
I will be replacing the maf later today. Is anything else you recommend? It is kind of weird to me that a valve seal broken from one day to the other.
Thanks in advanced!!!

I don't comprehend coolant getting through a valve seal. Head gasket is more likely. But does it smell like oil or antifreeze burning? They both have a distinctive odor, especially antifreeze.

Burning coolant smells somewhat sweet.

Not sure of your year car but several items to check as it sounds like a leaking head gasket. Pull oil dip stick and look for coolant on stick, do the same to oil filer cap. Lastly try running the car with the water cap open and see if bubbles and gas from the coolant can be seen.

With those codes, it is likely one or more air leaks. Care to share the details of the engine wash? Pressure washer?

I have never washed either of our Jaguar engine bays - far more harm than good is the typical result. A couple times per year, I wipe down the engine bays with an old towel, some silicone spray, and plenty of elbow grease. No water = no issues....
