1999 S80 T6 Occasional white exhaust smoke

[Riba]

It appears there are two sets depending on the engine serial number. I am having difficulties locating the serial number on my engine. Some sources suggest it is located on the back of the engine block on the passenger side, but it is not the case here. I found two candidates, one on the fuel rail cover and the other under the plastic cover on the engine head, but I suspect the serial should be stamped somewhere on the engine block. Can someone help/confirm? Thanks!

It is on the back of the engine. It's machined then stamped so should be shinier than the cast finish of the rest of the engine. It's a ways down, just inwards from the inlet tube for the passenger turbo.

Hmm, that's exactly where I was looking but could not spot it. I will take another look.

Found it, the leaky camshaft seal did what is necessary to make it had to find.

My camshaft sensor is leaking a lot of oil could tha cause a lot of white smoke with a blue tint ? The car is has misfire and rough idle when is get warm up when its could the car make a grinding noise but when the car warm up the noise gone at idle but it sound when i rev it up is sound like in the turbo of the driver side but the turbo look dry de only thing that is leaking a lot there is the camshaft sensor almos next to the driver side turbo coolant is good always at the same level the pcv system was done just like a week ago
