Re: 02 4.0 Main Seal Leak?
If your oil pan hit a rock it is most likely deformed at the rear lip right
below the main seal. You probably never had your main seal go bad, but your
oil pan is deformed now in that spot. Some careful hammering fixed mine.
I did the same thing years ago to mine.
Also once a 4.0 leaks it can always be fixed. Mine is an 88 with 200k miles
on it and it has leaked in the past but is dry now. Whoever said that isnt
much of a mechanic.

Re: 02 4.0 Main Seal Leak?
Then the 'mechanic' has no clue....
Both my engines are 'dry'. One has 315K km and the other 6 years on new
gaskets.
I even swapped an old oil pan over because one rusted out.
