Re: EXT :[Q-List] Oil leak - Cylinder Base

Jim,

My C150 was leaving a trail when I’d land and taxi, I thought the seal on the vacuum pump shaft was leaking, so I replaced it several times before I dug a bit deeper and tightened the bottom center case bolts.  That significantly reduced the oil trail I was leaving, and the oil consumption on my O-200.  Just saying, you may want to look at that while you are working on it.

Hey Bruce,

I also have an oil leak I’ve been putting off fixing on #2 and #3 cylinders. I think it’s the thru bolts leaking.
I’ve heard that the leak can be stopped by pulling the cylinder away, pushing the thru bolt out a little, wrapping silk thread around the bolt shaft, pushing back in place  and reinstalling the cylinder.

Please let me know what you found and how you repaired it.
