There's one behind the cam gear, but I thought that was the only one that could not come all way out by itself. :humm:

Well I figured out where the bolt came from. It was directly above the oil pump. I couldn't see the hole before, but after looking at diagrams, I realized there was a hole there.

Next goal: see if my turbo is rebuildable or not. I forgot my wrench set in my dorm today otherwise I would have gotten it apart while I was there.

That really is too bad. Sorry to hear this happening to anyone but the upside is that your motor may be fine. Was that a bolt location that was visible enough to be seen and tightened when the cover was off during the KDP job? If so, I bet it is one that is never checked by most people when tabbing their KDP.

It was visible when I did the KDP, but I didn't even think to check if it was loose because the KDP bolt was tight.

And yes, here's to hoping that the rest of the motor is okay. My oil pump came in this weekend, so really the only thing left is putting things back together and dealing with the turbo.

I bet that engine is fried,drove to far w/o oil pressure. I would pull the pan and a rod cap see how it goes from there.

With how this swap is setup, the oil pan can't be pulled without pulling the engine, otherwise that would have been my first step.

I had my oil pump crack in half like yours while i was driving on the freeway. I shut it off as soon as i noticed the light was on and towed it home. Put a new pump on it, and it was fine.

That is exactly what I should have done. I'm still regretting assuming that my gauge just stopped working.

I run the stock gauge and an aftermarket gauge tapped into the filter head - different parts of the oil system on opposite sides of the block. If they both drop, there will be no doubt something's gone terribly wrong.

There's no way I could have kept the stock gauge with my current gauge setup:

However, the stock Chevy oil pressure gauge was unreliable at best, so its not a big loss for me.
