You will need to remove the water pump to change the upper timing case gasket. It quickly turns into a serious overhaul.
Along with what BMe30 said, you may also want to replace the chain tensioner, flush and fill up with new bmw coolant. I would also pick up a M6 helicoil kit for any stripped valve cover bolts, I had 4 or 5 and just noticed another recently
