Default Why do I have carbon on my pushrod tubes?


I have this on the leading edge only of most of my pushrod tubes.

Not sure why???

No ops problems I think???

Should I be concerned?

Looks like baked on oil that dripped off of the baffle seal.

Broken or cracked pushrod retainer spring?? Common occurrence on 2006/8 vintage ECI cylinders.
