2006 Explorer Eddie Bauer
2006 V6 Eddie Bauer 40K miles. Getting a loud banging noise when starting the explorer when its cold outside. When it is warm- above 30 degrees F, it doesn't seem to do it. Could this be related to timing chain? tensioners? guides?
 






I would say that you are running too heavy of an oil for the colder temperatures and once the oil starts flowing better then you have more cushion on the moving metal parts.
 






The dealership changes the oil 5w30. Lately it has not been doing it. Although it has not been as cold, we will see what time brings.
