Yeah there's a few "While I'm there" jobs. I took the opportunity to do full CCV system replace, both intake elbows, valve cover gasket, both heater pipes, all the o-rings on the oil filter housing screw-on cover, dipstick o-rings, and of course intake manifold gasket which was rock hard both times. Both receipts ran me about 300USD from FCPEuro, but not all the parts were Genuine BMW.
No "special" tools required from memory, but you will need a torx socket set and I found a set of gasket picks useful for getting the broken ends of the heater pipes out of the head, and I found a mix of 1/4'' drive (access is tight on some of those nuts) with a wobble joint and bigger stuff was needed to remove the nuts on the intake mani. Be prepared to be horrified at the state of the plastic pipes...
