This is my first guess,but I would think the rocker arm.

 

very wild guess but...

how about the spring inside of a lifter?

but how would that be possible?

 

nope not the spring in the lifter, too big as I under stand, I was going to pull the valve covers tonight but ended up working 14 hours lol and looks like that will continue untill 18 days from now. Thanks for everyones opinion, but still no answers untill I can open the valve covers. I just hope and pray its that simple.

 

They are threads from the pan plug insert.

 

I have a stock lifter I can cut open for you if need be Kevin. I would think you would have more a grinding noise with the roller gone off the end of it to allow the spring to come out. IDK Kev you screwed it up real good

 

Interesting suggestion! All he need to do to test that theory is line the pieces up on the same size/pitch bolt and see if the pieces can be made to line up at all...

 

I DIDNT EVEN THINK ABOUT THAT ONE

 

pan plug insert???

 

The threads on the oil pan that drain-plug bolt screws into....but those pieces look too big and too round to be thread sections

 

yep they are way too big and the threads are fine
