Paul:
Next time you talk to the Mazdatrix guys, thank them for the great job
they did on my engine.
It's been on the plane for four years now, I haven't taken it off since
I installed it in Palm Springs June 2001.
375 hours on it now, never a problem. 540 hours total.
It did start leaking oil from somewhere around the front cover on the
right side after about 1 year. I've never been able to locate the source
exactly. But it's a low seepage that I just live with, not worth taking
the engine off for. I have to add a quart every 3 to 4 hours, but some
of that loss is injected oil - two remaining oil injectors in the
engine, the two from the intake manifold have been removed.
I recently completed a round-trip from Oregon to Kansas, the engine
continues to perform flawlessly. My biggest problem travelling is
finding mogas. I can't burn 100LL, it will foul my plugs every time.
