Crankcase Breather tube
 

O.K. So I thought my front seal was leaking as I had oil all underneath the truck. But now the leak seems to be slowing. Yes the oil level is good. So here is my question I had just changed my oil and probably over filled it a bit would this extra oil come out of the breather tube or is it wishful thinking?

If you have a oil leak then yes it will come out. but how much did you over fill it because its like the old saying goes (you have too much oil, its like having not enough)

it could. But generally oil leaks come from valve covers, timing cover, or tappet cover.

and the seal at the vaccum pump!

It was the crank seal I did it this past weekend took 4 hours and now no leaks.
