Mini ONE 1.4d: Bubbling from radiator bottle... is it the cylinder head?

 

So today we have a MINI ONE 1.4 diesel and guess what... it's overheating! Coolant is being lost somewhere and we find that it is bubbling out of the header-tank. My first guess in this situation is the head-gasket, but for a cheap fix (possibly, but better than going straight to ripping a friend's car apart) we tried a new radiator / header-tank cap, which was fitted yesterday and, although it has reduced the bubbling problem, there is still some coming out when the engine is warm, coolant lost and the temp. needle creeping up. 

This week the poor running has begun... occasional juddering, drop in revs and the odd misfire noise. Hmm... I have said to keep using it until the running becomes unmanageable (provided it's kept watered and is not overheating of course!) and am hoping for a weekend of better weather so I can have a proper look round it and, if need be, open it up. Watch this space.

EDIT: With not many tell tale signs of the head gasket being blown, someone has kindly suggested that the water pump is failing and not circulating coolant properly, so here's something else to look into. Yay!

Late '90s BMW Crossover Concepts...

 A couple of interesting concepts here from the 1990s that you might not expect from BMW, but showing once again that they were well abreast of current trends and design cues that would become prevalent towards the end of that decade. 

The first, below, is this strange high-roofline runabout / city-car that seems to be a mix of Fiat's controversial Multipla and the bubble Nissan Micra that both came along soon after. This concept also pre-dates the BMW MINI (and the 1-Series) that arrived at the turn of the millennium and was perhaps the fore-concept of BMW's small car range after becoming aware of buyers desires for high-end hatch-backs following Audi's A3. Either way, it shows BMW were having a go at that small-car big-interior vibe that has now become the basic staple of small car design.

The next, below, is a compact, convertible, sports-car, SUV. Yes, BMW are covering a lot of bases with their concepts around this time and maybe, with this beast, trying to wrap too many trendy cars into one package. The high-clearance quasi-off-road look makes sense with the success of the then recently released X5, but in my opinion giving a taste of what would come along many years later, with a plethora of smaller, sportier SUVs like the X1, X3 and of course the X4 and X6 grand lifted coupes. Interestingly, this concept has integrated 'wrap-around' wheel-arches like the odd Chrysler PT Prowler retro sports-car from the late 90s, though without the open-wheel stance. Was this to pass certain road-laws but still give the high-clearance look of a 4x4? Perhaps these were removable if you were throwing knobbly-tyres on and going off-road?? I guess we will never know.

E34 5 Series 'Countryman' Touring X-Over Lifestyle utility concept... with pop-out tent...what?!

Well, I really have now seen it all. This is something I never expected to see from BMW, given their sporty, driver-focused image, but here it is... The E34 5 Series Touring utility camping wagon! Not only is it lifted with bigger tyres and sports obligatory 4x4 style two-tone paint, but it even sports a 'pop-out' camper roof and folding tent! This idea was only ever adopted in one vehicle I know of and that was the truly ill-received Pontiac Aztec some 10 years later, with the tent thing actually being one of its saving graces! You heard it from Bavaria first.

The concept is of the early 1990's, which means it also pre-dates Audi's 'Allroad' Quattro and Volvo's V70 XC / Cross Country, both of which were released and saw quite a bit of niche popularity, not to mention Subaru's ever popular Forester that seem to still be seen all over. The Audi and Subaru of course had 4-wheel drive as standard and the Volvo has it as an option, whereas the BMW would have still only been rear-wheel drive.. Can't imagine this would have been too good on a muddy camp-site field! It certainly wouldn't appeal stylistically to the same sort of younger BMW driver's who drift round ploughing up fields for fun anyway and perhaps doesn't quite fit with the BMW ethos overall, so I can see why it was overlooked and never made it into production. X-Drive all-wheel drive only became a feature in this millennium, which would have suited this thing to a tee and may have even brought it into production, but with such a limited market maybe the world has moved on.

Personally, I love it! Maybe I will recreate one from my E46 Touring! I challenge someone to beat me to it!

This reminds me, I really must get on a 'camping' trip in the 318i wagon when the epidemic is over and camp in the car, which I've been planning to do for a while now. I thought I was the only one eccentric enough to have such an idea... but no, some design team at BMW had the same notion, only over 35 years ago!
