Hello all this is my first post in the gasoline section of Peach parts. I now have, or have had for about three years an 06 E350 with about 90K miles on it. Been driving MB diesels for years and been in that forum. We bought it as a CPO from the MB dealer with around 49K miles. It has had awhat was a slight knock, sounds like a main brg, at start up usually after sitting for at least 20 minutes. Now it has progressed to doing it at cold start up from time to time. I have an appt at MB Monday, I just wanted to hear from the gas side of the forum if there has been any history of this in the W211 series with the 3.5L V6? Thanks for any responses.
