going by the chain and colour of guides its a factory chain, the vvt sprocket have slight wear on their pulling edge inline with around 100k,, but the pics dont show the tensioner travel thats at rear behind under the inlet vanos sprocket,, that all said going by the guides colour and mileage of car and wear on vanos sprockets its well in the realms of doing, add the difference in where the cams sit with writing at the top all would make me if were my car replace it, that said i go my mileage for piece of mind, ie 60k seems to be the best mileage based point to replace it, as running on with out of time engine will start killing off other things ie cat and 02 sensors and make engine run hot as retarded and cause over heating of things like piston rings and valve stem seals etc,
added point here so when you see people do drag racing with 3000bhp and running NOS just 2 degrees retarded or advanced timing will melt it down. normal high performance car over time has a same effect but as they are not running on the limits of whats possible the engines take it for a while but does lead to damage. low emission cars run on the limits of only just enough fuel and air mixtures to run correctly upset this things start destroying them selves

Many thanks again will look at change as signs are appearing! Also I have a leak at the bottom of the bell housing please photo provided. What could be causing this no visible sign from above or around housing just at the bottom.
Many thanks for keeping this mini on the road!

rear end oil seal by looks of that, hmm gearbox out job flywheel out,,
i would check above that point on side of cylinder head for any leaks from the vac pump and oil pressure switch or the inlet camshaft vvt sensor ie 3x10mm bolts flat plastic looking thing with a strange black 90 degree plug on it. worth check all these first,,
then after this oil pressure test the car make sure its not very low due to crankshaft main bearings worn out, its poss to check this by putting a axle stand to lever against on front pulley if can get it to move up and down then chances are it something big,
first job oil pressure test it need to know how many psi or bar it has got, 3bar is perfect 1 bar at revs is broken when hot,, the whole engine needs clean good oil to run at its best, as vanos needs a stable oil pressure and flow rate dirty old oil effects them a lot,, 9k oil changes and seafoam oil flush every other service is a good thing, 5/30 fully synthetic low saps oil is also a good thing

Hi Mike many thanks no leaks from above so not looking too good. With timing chain as well I think it’s time to let the car go. You’ve been a great help and have enjoyed working on the car but just becoming too expensive if I can’t do it myself. Great cars shame they didn’t build them to last. Thanks M

its like all cars these days they build them to last past the warranty then its on borrowed time. trouble is a lot of people think that a 7 year old car with just under 100k is their new car but its someones old car really. i've lost count the amount of times i see cars 3 years old just out of warranty with big faults and a very angry owners saying it should last 200.000 miles before engine failed say, 200k yep most engines will. but not without wearing components needing changing ie timing chains and oil seals water pumps and dpf filter and turbo's they all are consumable items, that no one out side of the trade tends to agree with, its not just mini its all car makers even the very expensive ones,, Mercedes make top end cars, take the v12 twin turbo 500 engines they do turbo,s and when they do its engine out to repair, £1000 in parts and 2k in labour. its just wide spread these days as cars are made of plastics and cheap lighter metals etc produced in a country where labour is cheap, i'm dreading when all these battery powered cars start failing as parts will be so expensive it might be the end of DIY mechanics after a few of these cars get battery runaways ie the cells over heat and catch fire,, i would think laws will be put in place to stop people form touching the power packs i bit like the gas system and electric system in any house...
