White Smoke with video

"If it's the Valves or guides leaking or the seals, it would smoke every time you stopped for a Stop Light....."
Actually, no it wouldn't.
The valve stem seals don't need to be completely shot for it to smoke oil on start-up only. The OP says it only smokes on start-up, then clears.
That indicates that the culprit only shows it face After it has been standing for a a few hours. It only takes one leaky stem seal to allow oil past it to sit on the piston and smoke on start-up.
Admittedly, with the amount of smoke that came out of that exhaust on the video, I am highly suspect that more than one valve seal has gone, but without having the car in front of and seeing/smelling it for myself, it is only my best guesstimate.

This is it from me!
Sir John,
There is an unknown here somewhere? You said the Car was fine until you had the Oil and Filter changed and then you mentioned replacing a couple of Oil Hoses! What were those Oil Hoses and where did they go to? When you had them replaced, what reason did they give you......Also, where were the Hoses?
This would be nice to know......? And, for your information I am not an Auto Mechanic. I' just an XKR Owner living with my 4th Coupe....

I keep following this thread and I'm beginning to wonder why. There is smoke or vapor, but unless your nose is not functioning, the source should be discernible. Coolant smells sweet, or maybe like rolls baking, very different from oil. I have condensate vaporizing after startup on cold humid mornings, but it's not like the dense clouds described. Diagnosis is often very dependent on careful observation.

From your first thread (my emphasis):
I'll defer to the greater wisdom of those more experienced on the possible causes, but I'm also somewhat confused as this thread progresses. Burnt oil and burnt coolant smell very different, as RJ says.
I'm with Billy on this though at the moment. When something suddenly starts to happen after something else has been done, I'd be revisiting the something else first.

Sir John,
We've got to get this XKR running properly or Momma is going to Beat us both up! I know, as I went through the same thing 4 years ago......
#1 questions are did you just buy the car? and was it smoking when you bought it? Next you say that it smokes only once a day and that is at Start-up.
You also say it is not using Oil. Does the smoke smell like Oil? If the answer to these questions are NO! Then, you don't need a valve job, you don't need Rings.......That's when we go back to "Water" is the water low in the Morning? I mean is the car using Water? If so, that would be the source! Now, you've got to find where it is leaking....You were given an idea this morning with the Intercoolers....but that's only one idea as there are many more when it comes
to water!
So!!!! let's start ruling out Oil....Run down the list for Oil....1st if it doesn't smell like Oil....It Isn't! Pretty simple!!! Now move-on.....What else could it be? Something you are someone poured in the Gasoline?
If it's water, it will be getting lower each day! If it's Oil, it will be get lower each day......The Tail-Pipes appear to be pretty smutty around the edges.... Just for fun, replace the EGR value over on the Right Cam/Valve Cover....I don't think that will help but is as good a theory as doing a Valve job would be......If it's the Valves or guides leaking or the seals, it would smoke every time you stopped for a Stop Light.....
Start by checking the Water and Oil each day to determine if one or the other is getting lower....that is the quickest way to know.....

2. The smoke doesn't smell oil. I'm allergic and I identify smoked oil right the way. It actually smells good, like a brand new car (I know it makes no sense). For sure is not oil, or it is an oil that doesn't smell like oil. Is it possible that mobile 5w 30 full synthetic doesn't smells like oil when it burns?
3. Pipes are like that (smutty) since I've bough it, actually I was looking to replace the tips by the OEM and had no luck on finding them.
4. For sure is not smoking all the time, will try to shoot another video tomorrow of the car running.
It's a great idea checking the oil and coolant every day.
Thanks a lot, really appreciated!

That sounds definitely possible, do you know if the mobile full synthetic 5w30 can burn differently than other oil? That can explains a lot...thanks!

Lads, the car is in the mechanic now. The problem is related to the whistle I told you. If you open the oil cap, instead of blowing out air (something expected when there's a problem with the piston rings) it suck up air like hell, at the point that you have to use some strength in order to take the cap out. So what the mechanic says is that such pressure can be sucking either oil or coolant to the combustion area.
Without the oil cap in place, the car doesn't smoke...
What can be generating such pressure in that area? It sucks air from the valve area and push it back in the direction shown in the picture above...
Help lads, this is getting weird!

Unrelated, sort of. A member of a forum lost his oil filler cap. So he thought he would play it safe and block the hole with a sock.
Need I say more?
I know the CATS produce water as a byproduct but could water be getting into the exhaust system somehow and end up being evaporated as steam/smoke?

Called the mechanic, he told me that the SC it is working. He is clueless at this point and suggested me to take the car to Warren Henry Jaguar in Miami. Do you know them?

You always try to operate an engine under vacuum. This way, you tend to minimize the pumping losses that result from moving air around under the pistons, etc. Second, any exhaust gas making it passed the rings has to be somehow handled and passed through the catalysts for emission control purposes. It is done my connecting the intake "vacuum" to the block/head at the PCV valve. I am not convinced what you are describing here is part of the larger problem.

I'm taking my car to a mechanic that work with british cars. I'll ask him if he has experience particularly with these cars...
It's kind of an odd situation. I want to repair the car, whether is the head, the engine, but nobody can't tell me what the problem is. Why these cars have 1000 sensors if they can't tell you what's the problem with the car!
