After a couple of time hearing ticking in the engine, I decide to remove the cover valve to check what it could be. And I found out some flaking spots on intake camshaft. Did someone could tell me what could cause that?

Contamination in the oil system if my guess.
By that I mean like fine metal flakes

But is only on intake cam, the exhaust cam is fine. If it was coming from the oil the exhaust cam will be damage to?

Check it over real good. Check for damage on the rollers too

Rollers have some strippe on it but I think they come from metal flake debris of the cam

I remove the oil pan to see if it as other debris. Found some gold shadow in oil stay in the pan. Hope crank and rod bearing are ok. I remove the strainer and I found a roll strip of metal stuck in. It's not magnetic, so I think is aluminum. Now I have to found where is come from.

Looks a lot like the chrome plating on the roller rockers. ive seen stuff that in 5.3 trucks a couple times from the lifter roller but usually not in that big of a piece. check your rollers real close in comparison to the others.

All roller are fine, some have thin strip probably cause by the debris in oïl. It's not magnetic, so I think is aluminum and from it's shape I think is from a rotating part or holding rotating part. Next step is to remove timing cover see if could come from there.

the pitting is from worn needles in the rollers
