well i just pulled the head off my motor today and noticed 2 small triangle type of shaped pieces of metal in 1 of the oil passages, about the size of say a pinky nail. compareing them together it doesnt look like they should attack to each other,and there is a lip of sorts on 1 side any ideas where they might have come from??? i can get a pic of them if needed. i just want to know its not something that may be important, or at least have an idea where i might need to look for something broken off with that shape.btw both pieces look exactly the same from what i can tell.

thanks

I think a picture would make it easier to speculate

ill get a pic of it in the morning, though i did make a mistake its not in the oil passage its in the coolant passage, 1 of the small slit like ones
