Keep us informed bro.........fingers crossed for you buddy

Could also be a failed pressure cap so system will vent instead of retain.  Should be visible around the cap.

If you can borrow a pressure tester for Collins systems that will find it too.  Sniff test simplest of course 

Im perhaps not adding much other than to reiterate we haven't seen any reported head gasket failures on the forum as far as I can recall.

As for Steel-Seal, Im really rather sceptical of anything that can mend a blown head gasket just by popping it in the coolant. The pressures, heat involved etc would all suggest that it probably isn't possible.

Yeah.... gotta admit... watery goo to seal a head gasket does sound suspect...but Ive had friends use tgis stuff in performance engines on track days & it kept a vehicle going for years after treatment...

Just spotted the cooling dropped by 1 pint since yesterday..
AND
there was some mucky gunk floating in the water...

Any way,
Bearing in mind the engine has 170,000 miles on it...
how long does a Head gasket generally last on a 3.0 D Sport ?

I was going to throw a couple of cans of Steal-Seal into it & hope it seals it ?

Any ideas on this ??

Hey any update on your predicament?
Don't keep us in the dark!!!

Update Guys n Girls...

I think X5 Sport has the answer, that a week rad cap is the most likely...
The car has done some 4,000 miles since topping up & not lost a drop..

The logic says the cap is the likely candidate as the weak point, as she was driven VERY hard the night in question & the heat & pressure forced a venting at the weakest point.

Since then, simply done motorway mileage generally 80mph max at night or less, & not lost a drop since.
I will invest in a new rad cap shortly.... but for now, I'm greatly relieved that the engine is OK.

Many thanks to all for then great input & suggestions.
