Sorry for not being accurate in my description. The washer IS in the
garage. I am trying to drain the washer discharge to the kitchen sink drain
because the drain line in the garage is "blocked".

It would be nice for your readers if you'd post a picture somewhere. Your
description is inadequate, yet overly wordy. Why don't you just say the
washer is in the kitchen? I see washers in garages, against interior
walls.
"Inside the interior wall" could mean inside the garage..
If it is not in the garage, why don't you put it there? Who would want a
washing maching in his or her kitchen? Or is that a DISH washer?
My vote would be to put it in the garage, with piping exterior, as long as
code allows it. Aesthetics are of minimal concern in a garage.

I need to route a 3" PVC drain pipe from my garage (from the washer) to
the
kitchen drain.

There is an interior wall separating the kictchen and garage. The
washer
is
sitting against this interior wall about six feet from the exterior
block
wall. The kitchen sink is against the block wall on the other side
about
another 4 feet from the interior wall. So from the washer to the
kitchen
sink you have to route the drain along the interior wall, then make a
turn
to connect to the kitchen drain.

My question is, should I do the routing from the inside or outside?

Inside: Run the drain from the washer inside the interior wall. When
we
reach the exterior wall, make a 90 degree turn and go through the
interior
wall. The other side is the kitchen cabinet. Drill through the kitchen
cabinet divider and reach the sink bottom, then open up the wall from
the
inside, and connect to it.

Outside: Run the drain from the washer inside the interior wall. When
we
reach the exterior wall, drill a hole in the concrete block wall so the
pipe
can run through. Next locate where the kitchen drain is in that wall,
knock
it open. Once you see where it is, break the exterior wall from the
outside
and notch a trench that will take you from there to the kitchen drain.
Connect the pipes up inside the block wall, then cover it back up with
concrete, apply stucco and repaint the outside.

Which way is better? How do one drill a three inch diameter hole
through
a
conrete block wall? How easy is it to chisel out a trench along the
wall
to
seat a 3" pipe completely inside? I think that would be a lot of work?
I
think routing the pipe completely out and back in will be real bad
right?
