I suggest you get a big bright red 12 V. light - at least 1 inch in =
diameter - and mount it in the instrument panel directly in front of the =
pilot.  Radio Shack sells them.  Connect it to the EM-2 alarm output.   =
Set the max. temps for oil, water, egt, voltage etc above normal =
operating range but not nearly where any damage will be done to the =
engine.  Set the water pressure max. in the same way.  Set an alarm =
level for low voltage, low fuel pressure and low oil pressure.  With =
this set-up you will be warned immediately when anything goes haywire!  =
You may than be able to take action earlier that may get you on the =
ground quicker, save you, and maybe save the engine.

I've used this alarm system for 400 hours and it works.

  <insert favorite string of expletives here>



  Ok, to start this rant/post out, as annoyed as I am, I need to be =
grateful.  I flew the other day, Friday,  and everything was great.  I =
was just flying over the airport after some modifications to test =
systems (replaced the front cover o-ring AGAIN...this time with a small =
cylinder pressed into the hole with the O-ring around it to prevent it =
from slipping out...along with the silicone ring around the O-ring).  I =
was up about ten minutes and all my gages were well in the green and the =
engine seemed to be running solidly. I turned on down wind at about 1500 =
feet, looked down at my gages again and noticed my water and oil temps =
were both red with coolant temps at 260 degrees.  Damn.  Called for =
clearance to land as I reduced power.  Pegged my best landing and taxied =
back to the hangar without incident resulting in injury.



  I only had time to remove the cowl and note that the cowl was wet but =
had to leave for the day.  I returned the next day and started it up =
with only a little difficulty and noted the radiator was not getting =
warm...thus concluded no flow.  I ordered a new water pump from =
Mazdatrix with expedited shipping and installed it. I figured the water =
pump was likely twenty years old and a new one would hurt. Just as I was =
buttoning it up and reinstalling the pulley on the new water pump I was =
moving the stainless water hose out of the way for the wrench and =
FINALLY saw the REAL problem.  The stainless steel water hose had =
shifted and rubbed up on the e-shaft pulley and gouged two small holes =
allowing my coolant to blow into the atmosphere of greater Houston.



  Sigh.  Ok, repaired the hose today.  Filled the system with new =
coolant (still has some in the radiator with is under the engine).  Ok, =
for those of you in the know, you know it was hard to start (yes, I have =
been here before).  Finally, with much difficulty and a jump box the =
engine started...and ran well...but, after taking a few minutes to warm =
up, it jumped to about 200 degrees.  I shut down and as expected by now, =
steam came out of the tail pipe and I could hear the water boiling in =
the chambers.  Sigh again.  I pushed the plane into the hangar and =
pulled a plug, pulled the prop through and steam shot out of the plug =
hole.



  Ok, this sucks, but at least my engine did not seize and it kept =
running for a normal landing AND, I do know how to rebuild these things =
(even if apparently do not know how to properly tie back a water hose as =
not to rub on a fast moving e-shaft pulley).  So, the tear down is =
inevitable.=20



  Hopefully the damage is limited to the O-rings.....gee I hope I didn't =
warp the plates, I just cant afford that right now (so they most =
certainly are warped....).



  Just wanted to share.=20
