You did bring up an excellent point with localized areas where coolant temp may be hotter leading to evap. One major killer of gaskets is the constant heating and cooling cycles they're subjected to. Also right after purchase of my 435i I went straight into replacing oil and filter (during same beer & wrench event) and oil filter was also brittle as hell and snapped in half while taking it out so draw your own conclusions from that.

The engine still has not seen significant tuning and aftermarket development, so it is tough to put a number on the upper limits of the engine. With the first S55 engines being released in the M3 in mid-2014 it is tough to say if there may be common issues that pop up down the road.

Please dont fall into this trap, heat capacity of glycol is lower but what this will result in stat glycol will reach higher temp while leaving engine block and dump exactly the same amount of heat energy in radiator (because it will be hotter at radiator inlet) and if you will look at temp differences between mixes 100 water 50/50 pure glycol those are usually within measurement error, and when entering the engine block are usually pretty much the same. The cap leaking does seem to be a part of the cause. You can say we are somewhat N54 fanatics.
