my latest mini is in and ready for stripping down and refresh ,, this car has 80k on it and burns around 3 litres of oil to under 800 miles ,, its also feels very flat, I scanned it and flagged a oil pump control solenoid fault codes ,, so it will be having either a full oil pump or at least the control valve piloted from ecu,, head will be off tomorrow and then the bottom end hmmm bmw should be shot for mounting the transfer box in the way of one bolt to the sump ,, still un decided on how I will get around this and how far the transfer box needs to be moved etc either way its a mission, I already seen the timing chain is stretched from where the writing on camshafts dont match each other ,,, the n18 engines are direct injection like the n14 cooper s engines but they have added longer lift for inlet valves like the n12 and n16 engines and a exhaust vanos for timing as well ,,, hmmm even more to play with my day working out what is wrong etc,, this one i think has a few things going on, first off the crankcase is really black signs of piston ring issues and really burnt oil and maybe services had been 24 months and 20k ,,, these survive better with 12 months and 8k oil and filter changes,,, i also noticed and pointed out by owner its running glycol blue antifreeze,,, not the best way with these,,, I use neat pink antifreeze,, proof of this is when i bleed them the antifreeze will pool n top of gearbox and just never boils away,, where cars with water and blue after a week its all gone with the heat,, i also when using any fluids to any car only order it from MPD and with reg number and the list is pink for these cars,,, bmw have their own named antifreeze,, I use neat no water in it as water boils at 100c these cars run up t0 112c when fan fully on and sit around 105c on the road with air flowing,,, where the neat antifreeze dont boil until way past 100c and dont turn to steam as easy, i always check a car before working in it for a number of things,,, ie check no evidence of coolant issues and residue of a head gasket sealant etc, also do a full code scan and full live data run to see what is working whats not,, this car has a oil pressure issue that dont effect a oil light so should find the crank will be fine,, its just the controlled oil pressure to the vanos timing on camshafts is effected and that also needs to be gone through when its a part,,, every part I treat like it need to prove to me its not faulty etc ,, rather than taking for granted it should be, will add to this post as I go along as not put a countryman all4 up before ,,,
this car has codes for timing and oil pump burns to much oil smokes if left running on idle for to long and tap the gas pedal etc ,, and scrapes through emissions test for mot , what I do will sort all this and then some,,
