Background: I rebuilt my motor for my 87' Chrysler Conquest Tsi and finished it back in May but had a knock that I couldn't figure out after the initial start up, and then the second time I drove it it fell apart. I made it home but barely.
It's not pretty. I finally got around to pulling the motor out after it failed not even 50 miles after initial start up.
I pulled the head completely off and inspected the #4 cylinder as I had felt around it before and it seemed to have some cracks in it, so I thought the block cracked.
Here is what I saw when I got the head all the way off.

So here I can tell something has went bad and wore a nice spot in the side of the cylinder wall. Not good.
After much more time and work I got the engine completely out of the car and drained the oil pan.
I drained about 10+ quarts of fluid out of the oil pan, it seems that ALL of my antifreeze was in the oil pan. Oh, and my magnetic oil plug was covered in crap.
I finally got the oil pan off after the draining and pulled these lovely jewels out of the pan.

Then I got the #4 piston out and low and behold the culprit showed itself

I guess now I know what that knocking was that I couldn't find. It must have been a loose wrist pin or something and then when i got it to highway speeds it gave out. Now I have to start all over from scratch. I am tired of this motor and I haven't even got to drive the car but a couple times for a few minutes. I want to pull my hair out. Now what do I do? I guess back to the drawing board.
Do you think I can trust the other 3 pistons? Is there a way to verify they are sturdy enough?
I will tare the rest of the bottom end down later but for now I guess I will need to collect some new parts before moving forward.
