This is an often overlooked source of engine oil leaks that everyone assumes is coming from the oil pan or rear main seal. Most of the time it is from split CAC tube hoses that only appear to have oil moisture to them upon further inspections. Take a look I show you what to look for how it pools up and where it all comes from and how to change them out properly so the angles are correct and there is no blow offs.

 

Does this apply to the 7.3L also?

 

7.3l is a bit different but yes the same thing happens wit oil down the bellhousing especially from the boots on the intake those are the worst.
