Re: Found this in the oil pan
That is a wrist pin retainer - that is not good.

Re: Found this in the oil pan
Unless it was simply in there all along. As in it was never discovered when the engine was put together. Jerry, why was this discovered to begin with?

Re: Found this in the oil pan
I dropped the pan, pulled the head , the water pump and valve cover and manifold to re-gasket the engine. Valves, cylinder walls and everything else looks good

Re: Found this in the oil pan
With the cylinder walls looking good, I wouldn't worry about it.

Re: Found this in the oil pan
It surely wouldn't be from his buddy's engine. You were lucky to find these thing before it went blewy.

Re: Found this in the oil pan
I put over five hundred miles on this engine before opening it up. How can this clip fall out ?

Re: Found this in the oil pan
Maybe some "misplaced" it on assembly but you will never know for sure unless you do as Cape Codder suggests. I think I would just for my peace of mind.

Re: Found this in the oil pan
Can you move the pin back and forth without removing the piston to see if a clip is missing? Maybe with needle nose pliers or a hemostat? Perhaps with a home made tool.

Re: Found this in the oil pan
I agree with CC. If the engine is still apart I think and if the wrist pin can be seen if the rod is pulled slightly down far enough toward the base to see the pin and not disturb the rings. I'm not sure whether if that can be done on these though.

Re: Found this in the oil pan
At some point before reassembly, I will check them one at a time and will post results

Re: Found this in the oil pan
I have a question. Does the piston travel within the cylinder go low enough to expose the wrist pin retaining clip? My guess is it doesn't. If this is correct then the clip has to be an extra that someone forgot to remove or the pin was incorrectly seated and fell off during installation of the piston.

If the bores are fine, I'd remove the clip and press on.

Re: Found this in the oil pan
You are correct with the stroke not allowing the pin to be exposed. Check out my UPDATE

Re: Found this in the oil pan
If there is one missing in the engine I would expect to see score marks on one of the cylinder walls. That's why the retainers are in there, to keep the wrist pin in place.
They're not like the Model T where the wrist pin is clamped in the connecting rod to keep it in place..
