Checking the health on a 3.0 H6

I am seriously thinking of moving to the 3.0 Outback for its fuel economy. :eek: Have to say my current vehicle is a 4.0 Discovery2 V8 so anything would be cheaper :p

I know my way around an engine bay, I know how to DIY a couple of basic to moderate service items.

What are the specific things to look out for on these motors? Ignore the normal knocking the body to check for putty, frequent service intervals etc.

I ran through the gambit last year doing an ATF w/ filter flush, power steering flush, throttlebody cleaning, PCV cleaning, Oil w/ filter change, Front/Rear diff fluid change, Coolant change, spark plug change (this sucks on the H6 due to the frame rail clearance to the rear-most plugs), brake fluid change. Do these and your H6 will rock like it just rolled off the showroom floor. I get 25MPG now.
