Good morning,

Rick; The rockers on cyl.6 are brand new from Summit.

This morning I changed the rockers and pushrods from cyl.6 to cyl.8 and raised up the idling to 850 RPM.

Oiling looks better, but noise returns when engine is getting warm.

I noticed on exh. valve on cyl. 5+6 little bubbles coming out through the valve springs.

While replacing the valve springs and push rods, I also changed the valve steem seals as well.

Is this the reason for the bubbles - is it due to badly fixed valve steem seals?
