@bimmermasters: B58 or B48? Doesn't matter, same trap 🛢️ Both have closed deck blocks and forged internals, but they share a hidden issue nobody talks about. The plastic oil filter housing cracks without warning and literally floods the engine with oil. Instead of paying two grand at the shop for another garbage piece of plastic, do it yourself. - Pull off the cracked housing, clean and degrease the surface - Drop in a heavy-duty billet aluminum upgrade - And you're set for good.
