Expected life: 3.5 v6 in e350
New owner here of a 2009 e350. I am doing some budgeting and trying to figure out how many miles I should be able to get out of the engine block before a rebuild is required.
I was thinking 200k miles (ambitious I know). What are the common engine faults in this build?
Thanks!
I've seen plenty of the previous V6/V8's (M112 and M113) with 300-400k mi and diesels with over 600k mi without any problems.
