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