White smoke on start-up

As the title says, I'm getting white smoke on start-up from my 2006 4.2SC, it stops after a few seconds of idling. It's basically a good puff of white/ light grey smoke with a acrid (not sweet like coolant burn) smell.

I checked here and there's nothing that matches my symptoms...

There's no loss in power, no fault codes via the IID Tool and coolant level seems stable.

It's most obvious when I leave the car standing for more than a few hours.

Weather here is warm (28C plus) and humidity has been high if that makes a difference.

Is it something to worry about or is it just condensation in the pipes burning off, which I don't believe as then there shouldn't be any real odour to the exhaust fumes.

Any tips and advice would be great thanks.

Basically as suspected gasket failure and coolant in the engine.

So initially they'll strip back the engine and check everything. Hoping that it didn't make it's way to the crankshaft...

Currently, been quoted for labour, plus all parts to replace head gaskets, water pump, thermostat as well as machining heads and checking valve seating etc...

So a fairly comprehensive job for the old girl....

That's a comprehensive repair! Let's hope they don't have any little bits left over once they put it back together... Whistle 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

I hope it's not all in vein!!
I have the same model as yours and I had white smoke on start up once and it was noticeable but then it never happened again!

If we all point our RR's in the same direction and accelerate at the same time can we turn back time?

Cheers Scrumpy,

Shouldn't be in vain as the car using drinking coolant and the white smoke more noticeable all the time.

The garage has confirmed coolant entering the engine via the cylinder head gasket.

So the full strip down is to ensure the coolant hasn't reached the crank and the big bearings etc.

TBH it seems a bit excessive but I guess better to pay for it once and get it done properly then to have to take it back a few months later and pay twice... It's not exactly a cheap repair... 2006 RRS S/C CONSTANTLY under modification...

Once you're that far into an engine, costs tend to escalate due to the "While I'm in there" factor Laughing That's how I went from a basic rebuild of a 7.0 V8 into a new 7.5L stroker rotating assembly, heads, rockers, cam, throttle bodies .. Embarassed Embarassed

Still, might as well have them throw new shells etc in - those parts are cheap insurance Thumbs Up 2014 BMW 530d Touring, 2006 BMW 650i, 2018 Mini Cooper S

Few more things in fixing along the way, but 7ltimatwly these are wear and tear parts like front control arm bushes, discs, pads etc....
