Do you think 15 minutes is enough to break the cam in or do you think we should still break in the cam the next time we fire it up?
The pistons all look good and so do the cylinder walls but I'm waiting to hear back from my brother about his bore gauge to check the shape. I'm not going to work on it today but I'll probably take a look at the bearings tomorrow as well as the rings on cylinder 4 and give you guys an update on it.

An investment of around $150 will get him new GOOD rings and VERY GOOD bearings. Just a thought.
Yes....do treat the cam as needing to be broke in....You need lots of oil on the cam at start up...just to be safe...15 minute break in is usually OK..but with the way things have been going ....better to be safe than sorry.
I know you know this..oil with ZINC.
At least when you guys have the engine back together...you will know it is good.
