The International Cessna^® 170 Association

I need some advise & recommendations from the group.

I'm leaking oil from the oil filler cap. I've replaced the gasket after finding it to be loose. I also found the locking flange on the neck tube to be bent down and I had to tweak this back into position. I really can't figure out why that was bent down or was it just worn down. Never the less this was done and the cap was still loose but better so I doubled gasketed the cap. (Doesn't seem to be the way this should be done) Seems to be tight and secure but oil is still coming out and making a real mess on the belly of the A/C. Can this filler neck tube be replaced with a new cap also? How is this filler tube removed from the crankcase?

On going with this, I recently had a plugged crankcase breather line. This was taken care of. I've been using the Exxon Elite now for 2 years. Don't understand where these gremlins are coming from.

Any thoughts from the readers will be appreciated.

The gasket is supposed to be "loose". It merely resides below the tabs on the cap. If it's cemented tight it may not conform well to the outer diameter surfaces of the filler tube. The cap should have some resistance as it turns into final position on the tube. Keep the crankcase breather tube free and clear.

I was having an oil leak in the area of the filler neck that turned out to be the "O" ring on the dipstick. Make sure this isn't your problem...Russ Farris
