Glow plug failures

[Tony Stillman]

Don:

Yes, I am hearing similar stories all across the country.  The air flow over the crankcase does seem to improve bearing life.

    Also, I think everyone is paying a little more attention to the temperature, especially in the crankcase area.  New models are showing up with air scoops to direct fresh air over the rear bearing area, and I'm sure that helps, no matter what engine you are using!

  All, I agree with Tony's comment on temperature, after the Fresno contest this year, at Jerry Budd's suggestion, I installed some airflow 'diverters' that forced air over the case and lower portion of the crankcase to keep that area cooler.  Had plenty of air flowing around the head and upper case but no directed flow over the lower end.  Not a scientific measure by any means, but I think it helps, I intend to do the same in future planes.
