My solution is to add oil when it gets low and tighten the bolts if necessary. I wish BMW gave iron bolts for this application as I'm nervous about retightening aluminum bolts that have a history of snapping.
Your sig says you have a 328i, you shouldn't have Aluminum bolts, you're should be steel.
Only the 2006 models with the original N52 motor have aluminum bolts as we have a magnesium valve cover. Yours should be plastic.
