>>1855720The problem is not that they are unreliable, it's that these engines were (and are) very expensive to build and maintain, since engines have to be overhauled after x hours. Even just changing the sparkplugs was a pain (all 56 of them in that particular engine)
>>1860894My bad, meant the jumo 205, which is an opposed piston engine that doesn't even need cilinder heads.
