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.
