Please post a picture of what you are asking about. your description does not tell us anything useful about the back of the engine block. I do not recall ANY balls back there and I have a spare block to look at.

Your truck probably has a standard transmission, right? I've seen similar things a small handful of times, always with a standard transmission. I believe that these are from a throwout bearing that flew apart from not being replaced soon enough. If it gets bad enough for them to actually fall out when the bearing falls apart, the spinning clutch and flywheel can throw them around inside the bellhousing. Usually, I've seen these stuck on the lowerpart of the bellhousing and they are stuck in a mixture on grease and clutch dust. I've seen them stuck on the inspection cover in the same goo a couple of times. If everything was working fine before pulling the engine, I wouldn't worry about them. Some of the trucks I've worked on weren't very well maintained to be REALLY nice about it. Truthfully, some were a real POS, to be not quite so nice.

If it was a manual, probably from a DMF that failed. Stupid DMFs...

Yea see i thought it was the throwout bearing also cause my clutch was grawling at me before i took everything off but ill check the starter and see waz up thanks for the replys.Im trying to do all the work my self i aint no mechanic but everything seems to be pretty straight forward the onlything im not doing is the heads they were replaced not ro long ago so im gonna leave those alone.

Where are the metal balls in a DMF?
I've only ever seen spring parts come out.

They may have them, but I've never seen any either.

On the dmf, the part that bolts to the crank is a bearing that doesn’t get used until the internal clutch in the dmf slips and makes the whole thing garbage afterwards.

Thanks. I learned something today.

Well, it does get used slightly before that - that's where the 5/8" of rotation "free play" pivots on.
There's lots of those ball bearings in there - two whole bearings worth(and at 3"+ in diameter, that's a lot of balls).
