• 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.

Hi everybody.
I have owned a Pitts S2A, S/N 2149, for 9 years in France. Nice plane. No problems ever except oil pressure oscillation during normal flight. Pressure stays in the green area but the oscillation seems to get bigger lately.
This happen when oil quantity is less than 6 quarts and stops around 7 to 8. Engine is a Lycoming AEIO360A1A.
That oil oscillation deasepeared when I replaced all hoses 3 years ago. But it has started again during last summer. The full Christen system has been inspected and cleaned but this has no effect. If anybody has encountered the same situation, I would be happy to hear about it.

The full Christen system has been inspected and cleaned. No change.
