White smoke from RR classic
Discussion
This all rather depends. I presume it's a 4.2 V8?
HG would mean coolant loss and likely mayo in the oil cap and contamination in the header tank. If it's none of these.....
Also if it's burning water then you'd get steam not smoke!
White smoke is often turbo bearing failure, but if it's a factory V8 then it won't be.

Yeah he's not with the car so I cant ask him to check those things annoyingly.
You're right its a 4.2 V8. He says billowing white smoke coupled with lack of power.
its only done 15 miles while like this so hopefully no damage done.
He only bought it just over 2 months ago so i hope its not expensive.
Thx for advice btw

isn't oil smoke blue?
white smoke is steams usually, and more often than not is a complete head gasket failure in a RV8- could be even worse though- ie cracked block with a slipped liner.
If its a little getting mixed then yes, however if it's a lot getting nicely burned then it will be white. Check out some vids of racing cars giving up the ghost etc or drip some (not much white smoke is steams usually, and more often than not is a complete head gasket failure in a RV8- could be even worse though- ie cracked block with a slipped liner.
) on your manifold when hot.Anyhow, the valve/valve guide option twas only a suggestion.
If it isn't steam and there is no water in the head then it would have to be a good amount of oil coming up via the valves or pistons.
Usually if it is the pistons then it's typically down to wear and tends to be that classic grey smoke when coming off load. Also, unless you wouldn't get a massive drop off in power.
If it is literally that classic heavy White smoke and it suddenly appeared along with a sudden loss of power but with no increase in noise from the engine then it sounds like a seal going in the head or something having dislodged rather than anything actually breaking and opening up a flow path from bottom to top.

Bit of a wild stab.
What colour are the plugs? Could it be seriously overfuelling I have seen this happening when the intake air temperature sensor misreads causing the ECU to assume it's cold on Fords. On a RRC there is a coolant temperature sensor by the top hose on the engine that tells the ECU how cold the engine is. I've had a 3.9 V8 with do something very similar so it was running very rich read about 6% co on the gas tester at normall running temperature. Could be either be low coolant or a duff sensor. I swapped the sensor out topped up the coolant and changed the plugs and it was spot on after.
