Is this bad?

Hoping for the best!
I just changed the break in oil on my ZZ427 after fifty miles of easy to moderate cruise.I primed the engine and used 5w30 non synthetic for break in.
I flipped the oil filter into a clean container overnight and found very light flakes in the base of the container.
Is this normal break in material or something more serious?
Engine runs fine with no knocks but does have a slight lifter tic.
Any concerns?

Re: Is this bad?

This is normal during break in. I wouldn't worry just yet, but, if you're really concerned send it to Blackstone Labs for analysis. Is the valve tick throughout the entire valve train or is it just one lifter? You may have a stuck lifter causing the cam lobe to slap the lifter resulting in premature wear. Dunno!

Re: Is this bad?

Re check the tappet settings.. those head torques valley cover torques all require re checking...
I cant really make out exactly from the picks, but a little very fine 'metal flake' like a fine paint metal flake is normal ... things like rings beding in

Re: Is this bad?

You are always going to have some wear initially til everything mates to one another. Scary though if you have never experienced that before. Also as stated, you will want to recheck lash on the rockers. Generally after break-in, stuff wears in a bit, and you should not have to reset after this for a while.
