Hi all. Up at 200,056 km (~120k miles) so decided it was time for a 60k. Took 3-days on and off but its done 
Started Friday morning by cleaning out the garage and fitting this beast of a car in there, this thing takes up more room than a minivan! Friday I stripped her down to the timing belt cover and crank pulley, decided that the dust from the wheel-well liner was telling me to call it a day.
Saturday things got interesting, broke two things but fixed them, middle timing belt cover where the plastic loops around a metal braket on the firewall side of the engine (easily fixed with epoxy) and the metal window attacked to the crank sprocket which the CPS slides around, bend it back with subtle pressure in a vise.
Sunday was spent putter her back together, althought my replacement Alternator/AC belt is way to tight, tensioner does not even fit, have to replace that this week. Getting the bubbles out of the cooling system got the temp guage as high as have ever seen it, well past the N in Normal. Managed to make her stall a couple of times, but the ECU leanred things pretty quick.
Overall a good experience, glad I had an experienced mechanic with all the proper tools and 10 years of Mazada-dealership experience to help out, he was amazed how the timing marks stayed aligned even after the tensioner was put in place, apparently the 2.5 and 3.0 litre Duratechs don't play so nice, one cam skips a sprocket tooth once pressure is reapplied. In the end I changed the timing belt, crank position sensor, crank seal, water pump, accessory drive belts and thermostat. Standard fluid replacement as well (oil and coolant).
Now at least I have eliminated the CPS as a source of Check Engine lights, and with the O2 sensors having been replaced last summer I think its about time I stopped being lazy and read the codes
Note: Valve-tapet adjustment was not necessary this time around, all the shims were in good shape.
