I think 51-Merc-CT has it figured out... I put an arrow pointing to it in his picture... So, this wasn't in the valve valley, but actually in one of the intake chambers?
Wow it does look just like that! did they have threads on them though?? Do you have this one in the picture? if so what are the dimensions of it, length and width, seems like it would be a rather large hole to drill into the boss? have any more close up pictures of the entire tool? this one has threads on it, in the middle. It is not made of silver, it's definitly steel, just all polished and shiny. and It was in the actual intake runner, just below the valve head. This engine does not have adjustable lifters, but has been machined and sleeved back to standard so it must have been there since rebuild??
Looks like a little T handle off a small tubing cutter. Ok, I don't know what it is, but it's the nicest one I've ever seen and I always wanted one.
Where did my anti lifter rotation tool go? every time I rebuilt a motor I lose at least one tool . . .
After further review, I concede that it's not a cuticle tool. Looks like most have a pointed end as well. So far it appears to be a knife or silverware rest as it's a bit fancy to be inside the motor as an anti-rotation pin. Thus, not:
This is just what I hear. Don't want to start any rumors. Maybe Crazydaddyo can expand on this theory more.
I'm convinced! My dad stopped by and I asked him what he thought it might be. He said, "Its a tool of some sort, I can't remember what though." I scrolled down to 51 MERC's post and he lit up exclaiming "THATS WHAT IT IS! WE USED TO USE THOSE WITH ADJUSTABLE LIFTERS SO THE LIFTER WOULDN'T TURN IN THE BORE AS CRANKED ON 'EM!" Okay, whats 51 MERC win?
Thanks Scooter. Scooter is correct. It is not widely known, but what we know as dryer sheets now were originally used to increase the performance of early Ford vehicles. The sheets would be wrapped around this little metallic pin. Every 2,500 - 3,000 miles (which ever came first) you would drop one down the throat of your carburetor. As the fuel air mixture passed over the "dryer sheet", a molecular transformation would increase the octane of the fuel and as the sheet deteriorated it released Nitromethane. The government eventually banned the sale of them as the little pins were casing the death of hundreds of thousands of muddy mud skippers in the pacific north west. The inventors inadvertently discovered that the sheets also made your laundry smell good. So now we have dryer sheets. If you don't believe me, Google "Dryer Sheets". .
What he also failed to mention was that when they found out how convenient the roller was, they switched to a single handle design for ease of use. (new, more-modern version shown. Also note it has a hole in the handle for storage possibilities)
I didn't mention it because the use of dryer sheets for anything other then automotive use would be off topic. .
That is the "FISH" out of one them 100 miles per gallon Fish carburetor, at one time that motor had a Fish carb on it, when the fish gets out of the float bowl the carb acts like any other carburetor. It will bring big bucks on ebay...... tt
Looks like a "burnishing tool" -- used to apply and smooth out gold leaf or other very thin and delicate foils. No, I didn't make this up.
Just remember to put it back in the engine when your are reassembeling it as the words of the shop teacher "NOW WE WILL HAVE NO PARTS LEFT OVER WHEN DONE WITH THE ENGINE PROJECT" As if it came out it has to go back in >>>>.
