I have just bought a new oil breather for my 2001 X5 diesel. I have bought the later vortex one.
I am going to fit it tomorrow. Would you still recommend changing this every 20,000 miles or is that just if you still have the old style, with a separate filter in. I only do about 8,000 - 10,000 max a year. I will be changing my engine oil & filter every year. My x5 has done 70,800 miles. I am changing the breathe as a matter of caution as I have just bought the car & don't know if it has ever been changed.
Any advice will be appreciated.
