280,000 miles. X5 has multiple problems. But keeps on trucking. Major problems with at least two cylinders misfiring. Have been clearing codes on the fly for misfires on cylinders 1 and 5 for the past year. Like 10 to 15 times a day clearing codes to keep her going. Huge amounts of blow by gas which I now channel directly out of the valve cover into a hose leading down and out the passenger side. Totally bypassed crankcase ventilation crap. Constant drive shaft problems. This time center support bearing out again. I just did the hose and zip tie thing. Sort of clunks around but got me from Oregon to Utah. Missing gas cap. Oil leaking. Headliner drooping. Going for 300,000 or bust.
