seems the housing where hoses attach in leaking
(1) Answer
Is it a full size blazer or S10 blazer?

I know the full size blazer has a O-ring and gasket kit to fixes those leaks.
If the hoses aren't leaking,most of the time you can remove oil filter
and the 2 bolts that hold housing and pull housing down.
