rear engine oil breather
Ive just noticed oil from the rear breather which is going onto the prop.
this has just happen quickly. I keep the oil level at 6 quarts so dont think its overfilled. any ideas on where to start ? 1977 337 G normally aspirated. around 800 hours on engine. engine runs perfectly normally with no other "leaks" |

A little oil, or a lot? Did you notice a much greater oil consumption versus normal?
Are you certain it’s not the prop grease or oil leaking? Do you have an air/oil separator installed? Last compression check ok? Power-stroke combustion gasses might slip past sticky rings and slightly, temporarily, pressurize crankcase and push oil/foam out the breather. If you think it might be stuck or sludged rings, download the piston-ring flush technique free from the savvy aviation website. https://resources.savvyaviation.com/...vent-flush.pdf Keep us posted, please! |

Are you new to the plane? That’s pretty normal for Skymaster
