Then you have tiny hands. I estimated the size by moving my hand forward and back in front of me until it was the same size as the screen image, then placed a ruler in the same plane to measure the ball. I remeasured and got 7/16". Can you tell us the diameter of the ball?

Way off... big hand -tiny hand ????? ..you do not use an unknown to factor...

You use the bore of that engine and then calculate the pic ratio.

The results are 9mm...

The impression does not necessarily represent the full diameter. Your measurements only bracket the low end of the diameter.

You'r kidding?

You want to compare a hand comparison to a carbon copy of a cylinder???

Put up some $$$$ for when he measures it for us....the method I used is way closer than your Hand measure...you use HANDS when you measure a Horse !!!!!! ...hahahahahaha

Ever done a Brinell test?... or know the principle behind it?

No need to get in a huff, Arthur. I was actually going to compliment you on a more exact way of measuring sizes from photographs until I realized a ball doesn't leave its full diameter when it makes an impression. It's still an estimate.

No huff...and it is an Estimate..
Your estimate just seems to be a larger estimate than mine or the posters.........

My point was how one arrives at the estimate...that's all.
If the hand was that of the Jolly Green Giant, I would prolly agree with your estimate.....

Ever see what a 1/2 ball looks like in your hand??
I have ..work with them all the time .
They are large..that is not....

well after that I had to go out there and measure, only problem is- I couldnt find anything to measure it with, so for comparision, thats a 7/16ths drill bit next to it.

If it were my engine, just for my own curiosity, I would determine if it were indeed possible that this ball came through the intake valve.

Remove the valve spring and see if it will clear, and if so, how far the valve must be open. Certainly it would take more than 7/16", but .438" is not exactly high lift.

John,
Here is an old trick when you need those type measures and you don't have the proper measurement tools...

Put what you want to measure in the jaws of an ajustable wrench and close the jaws to hold the piece...then simple measure across the jaw opening. turns your wrench into a crude vernier. Can also do the same with a vice ...same deal, close the vice to hold the piece and measure across the jaw...and if you don't have a rule , once the jaws are set , then slip a known drill bit [ not the flute end] into the same jaw opening until you get the right one and that is the size.
Buy some verniers...they come in so handy that once you have some , you will be amazed at how many times you will use them, from hole sizes to finding bolt threads. etc....

Maybe it came from a turbo blower, through the air intake?

Turbos have plain bearings. Run on a film of oil.

Eh, that depends on the turbo, but I would suspect much smaller bearings in the ball bearing versions that go on cars.

This should be interesting if the true cause ever surfaces!
