F20C pearl

 

wooow, that's crazy!!

 

Pic needs a size reference. Whatever it is did not come from anything originally installed in the engine.

 

theres a couple of those in my vents, the ones in my dash.... they were they from first owner =.=

 

Wow that's neat! Glad to see your baby is okay!

 

I'm thinking it's from a tumbler too. The baffles inside the valve cover probably trapped them and they vibrated out over time.

 

WOW!

Definitely looks like powder coating ceramic beads.

ding ding ding, looks like the guys did the powdercoating did it in a hurry.

when we media blast stuff, we use a chemical bath to raise off everything so there's no foreign objects.

those little sucker is like sandpaper in a ball shape, hopefully not much get dropped into the head, or worse, jam up oil passage inside the block

 

it's hard to judge the size but they look too large to block an oil passage, I doubt you'll find anything in the oil pan unless they broke into smaller pieces.

 

Do they float on water / oil?
Tumbler marbles don't float as far as I know.

The oil return from the head is large enough to let them pass I think.
Going by the size I think they are looking at the picture (5mm diameter max?)
