• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

Before my engine rebuild I would seldom see oil temps over 170F. At cruise settings I would see 170F, and when flying a full-power airshow flight for ten minutes on a 100F day at high density altitudes, the temp would drop to 160F. Since the rebuild I get to 185F on climb-out and have to reduce power. At cruise settings the temp quickly drops to 165F, then almost immediately begins to rise back to 185F over the next five or six minutes, where it then stabilizes. This is very consistent behavior. I am trying to figure out why the temp would drop when the power is reduces, then immediately begin to rise again at the same power setting the brought on the reduction of temperature.

The oil cooler I have is the one provided by Kimball, and has always worked perfectly. It has a thermostat (Vernatherm) and has been flushed recently Any ideas?

Thanks,

Danny
