engine tune up and repairs!?! Help

[CarlosT95]

I bought an 01 BMW X5 4.4i it hasn't had any work and I want to know what parts should I replace because it's doesn't look like anythings been done to it.
I changed sway bar link at front that's all. When I drive the engine heats up a lot like I can feel it from like 3 feet away and it smells like it's burning oil. I would like a list of parts I should look at and change to have a perfectly working engine with no problems whatsoever. It has 239k Kms and want it to last me a little longer any one know how far the engine could go kilometre wise?
Thanks for looking at my post
