340 with metal in oil pan

Post #27.... looks like a different piston in the next hole.. or that next hole has the piston right side up. (I think I can see the edge of any eyebrow....)

Goodness....everything needs close inspection.

To all you people who thought it was a valve seat.... how in the **** can it get in the oil pan without a hole in the m'fn piston...
Yup....
