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?
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.
