Chevrolet Repair: 1998 Blazer 4.3 oil leak, oil hoses, transmission cooler

Question
The two pair of oil hoses are leaking both to and from the oil filter.  The hoses running up look as though no big problem to replace.  

How about the pair running back along the driver side of the engine just above the crankcase rim?

Auto Zone has both sets available with fittings and seals.

Thank You,

Lorin

Answer
one side is oiler cooler the other is transmission cooler , both are pretty easy to change,
although easier to do on a lift. sometimes easier to unbolt the motor mount and tilt the
engine a little.

this is a real common problem on these vehicles. more so on the oil cooler than the
the transmission cooler lines.

I hope that answers your question. if not let me know.
