Camshaft cooling nozzles?
My io-382 is about to be built.
One option is camshaft cooling nozzles.
Do these provide any real benefit to engine or cam longevity?
Thanks,
Tom H.

My understanding is that lycoming engines have some difficulty getting sufficient oil to the cam shaft because of its position up top and as a result, frequently show pitting and wear. "Ney nozzles" provide additional oil to this area and are recommended by many, including Mike Busch (see his EAA webinar "All About Oil")

I have them in my IO 360 A1A. There have been some nay sayers on this forum with nothing but "I heard" comments.
I have had them for 1000 hours, no problems. I have nothing but good things to say about Chuck Ney.

The cam nozzles are for lubrication not cooling. Some angle valve Lycomings have piston cooling nozzles, similar but different purpose.
Google Ney Nozzles for a lot of information on this subject. |

The Lycoming has a tendency to eat up the cams and followers. Lycoming Flyer has several articles about it. I would do it if I had the option.

Fly the plane and you have nothing to worry about. Even with a Cam lube nozzles, if the cam and tappet bodies are allowed go dry... then rusts and pits, you will have the same issue.

I think they provide great benefit. I wouldn't build and engine for myself with out them.
Good Luck,
Mahlon

Mahlon,

Therefore, does mine have nozzles?

When I had my engine built by JB Aircraft in Sebring FL, he recommended this be done. He had ECI modify the case for the cam squirters. Here is a picture of them. You can see the little gold colored nozzels below the cam. Thread on the rebuild here.

Thanks to all for your feedback. Hearing Mahlon's comment just cemented my decision to have them added during the build.
