Technically speaking, only
Technically speaking, only inline-engines can be purely vertical. But I agree- flat or opposed motors tend to be more prone to seepage when not in use than a V. I’ve always liked the older GM 60-degree V6, especially the last domestic pushrod (2004 3.4) for this very reason. But it’s 2021. We’re never getting the good old days back, so now I’d rather have a Tesla. Until then, I’m just happy my wife’s 2019 Legacy has full coverage. Her 2011 Buick LaCrosse CXL AWD was the worst car I’ve ever had. Had to replace engine, transfer case, and rear drive shaft. So happy to trade it for a CPO.Subaru. RIP GM
