and well make the oil look like metallic paint

New to Cummins, Possible Dead Oil Pump?
 

Cam bearings are made out of much harder material than the journal bearings. Could be cam bearing material or a full on failed journal bearing. Either one will cause a major oil pressure drop.

Oil did not look like metallic paint, it looked like normal used oil with a couple metallic specks here and there (but not many). Think something could have failed behind the front cover?

:humm: KDP took out oil pump gear possibly :scare2:

Lets hope you get lucky and it is just the oil pump. go fishing in the old oil with a magnet and see if you get an more metal out of it.

I went through the rest of the oil with a magnet and just got a few more tiny specs, no chunks or anything. And I literally did the KDP fix less than 200 miles ago and loctited the bolt in, plus it was nowhere near out when I checked. Maybe something else came out behind the cover? I need to find a spot other than the parking lot that I can wrench on it, so I can take the front end apart to the point where I can easily remove the front cover.

Did you loctite all of the case bolts ? :c:

I don't like the looks of that drain plug at all. I'm thinking top-end issues, based on the way it went down.

The only bolt behind the front cover that came out was the one for the KDP fix and it got loctited.

What makes you think it was something in the top end? I feel like the oil pump had to have failed to start it all, since the first symptom of something wrong was my oil pressure disappearing.

Here's How I See It
 

From what you stated originally:

Engine had 300k miles. Maintenance history? Valve adjustments?
Turbo blew. Oil pressure went right along with it, since there is no longer any resistance to flow through the turbo feed.
KDP was already fixed, so what makes the clunk in an engine like that?
Something came apart, most likely dropped a valve or 2, would be my guess.

Like was asked before: Where does the ferrous wear metal come from?
