The first engine is the Acura/Honda 3.2 DOHC V6 (not sure of the actual designation), currently used in the TL and probably a few others.
The second engine is the BMW M54 3.0 I6, used on e46, e39, and a few others up until recently.
Does anyone have some experience or knowledge about both to tell me which of the two is a more bullet-proof design? I looked at the UOAs, but there are only a few. The Acura engine appears to have somewhat elevated metal levels, but it may be a normal break-in behavior and not a concern, I'm not sure.
Are they relatively easy on oil (how big are the oil sumps on each?) and capable of going way past 100K miles without major issues? Are there any known inherent design flaws in any of them?
I know you can't judge a car by its engine alone, but it's just one more point of decision-making process for me.
Thanks!
