Looking for some feedback related to an option for extending the longevity of my X5 4.8i. I have the opportunity to purchase a used 4.8i N62 engine that has 40,000 miles on it. My current engine has 150,000. Can I expect less wear and tear on the engine itself but the same rock hard and ready to break gaskets/seals? Any benefits to this swap? I figure that the $1,000+ leak repairs in the future would easily add up to more than the cost of a used motor with these miles. This swap would allow me to keep my current engine and do what I want with it. Anyone with helpful opinions is appreciated.
