Hi Jason,
 
Sorry to hear about your problem, but better to = catch it=20 early on than later. 
 
Were you by any chance seeing a pressure build = up in your=20 cooling system while flying?  Most of the time a leak like that = will end up=20 with coolant in the housing and high coolant pressures as the combustion = gases=20 pressurize the coolant system.  Can also cause lost of coolant not = only=20 through the hole, but also by having the higher coolant system pressure = blow=20 coolant past your radiator cap.
 
Here's my 0.02 worth on the rotor housings = - keeping=20 in mind I am fairly conservative about the condition of stuff in my=20 engine.
 
If your engine were going in an automobile, I = would not=20 hesitate to say, "yeah, go with the housings despite the missing = chrome". =20 However, I personally would not put it back in my airplane.  = There's no=20 doubt you could still put some hours on the housing but eventually = (probably=20 sooner rather than later) you will end up replacing it.
 
Also while you have the engine apart, check the = wear on=20 your apex slots in the rotor.  There are limits that Mazda says = should not=20 be exceeded and its one thing that many folks do not think to = check.  A=20 quick and dirty check as related by Lynn is to take one of the apex = seals and=20 stick it end wise into the apex seal slot.  Then measure the far = end=20 (sticking out) as to how far it moves when you tilt the apex seal from = one side=20 of the slot to the other.  I believe Lynn indicated that anything = beyond=20 3/16" movement of the far end means your apex seal slot is worn beyond=20 specs.  I am convinced that is what caused an apex seal on one of = my rotors=20 to break and destroy the rotor - used rotors with worn apex=20 slots.
 
Get it back together and keep flying.  Good = luck.
