In this video I go over a common oil leak on the 7.3L. It is one that is often misdiagnosed at least initially as all other oil seepages on the engine go right past this one on their way out the engine valley and down the backside of the engine collecting on the bellhousing. If you have a good oil leak on your 7.3l this would be a good place to start. There is a updated part to resolve the issue and a special Loctite needed and I go over all of that too.
