hey formula,
well I have followed the cam breakin procedures to the letter from cam manufacture. As fate would have it it had a ticking noise right from startup. Never got better. Ran 30 min. Decided stuck lifter, tore it down to look and found that several lifters had metal particals on the end touching cam. Cam appeared to not have a consistant wear pattern on the lobes either. Called cam manufacture and they are going to replace cam and lifters. Have you heard of any of them helping on some of the labor costs also. This is getting old pulling engines. Getting way to intimate with this project.
By the way, used rotella 30 wt and 1 pint of eos oil additive. Fired right up and ran 2200-2600 rpms fo 30min. I'm at work now, offshore, check email every few days. thanks for any insight.

I will be sweating a new flat cam breakin real soon. All I can do is pray at this point. Labor, I doubt it, your lucky to get the parts.
