Hello Everyone
Our RV-8 with XP-360, fitted with inverted oil system has 5.5 hours now. We are experiencing an oil pressure drop during inverted flight. We checked the christen inverted system and it was operational. We then checked out a Pitts S-2A with Lycoming AEIO-360-A1A and the systems plumbing is fitted to the vacuum pump plate with the breather T'd into the system. Does anyone know why some Lycoming engines have the system fitted to the breather and other to the vacuum pump plate? And why this makes such a big difference? And which Lycoming is the most similar to the XP-360?
Thanks
Don and Mike
