Other than that, keeping my fingers crossed here at the very least Ill pull the magnetic drain plug that should tell me something before I start taking the car apart.Ill keep the updates coming
I would start up top with the cam caps but eventually you have to pull the pan too. The cams will take a huge beating before the other components in my experience. They are starved of oil first and the aluminum shreds quickly.

You don't have to drop the subframe completely. Just let it hang down so you can get the oil pan off.

It is possible that you just starved the lifters a little hence the tick and other components are ok. The fact that your light came on at 6k can be a bad/good thing. If your nut came off at that very moment and you caught it in time would mean you had full on oil pressure at the time of failure. I say pull the pan and do a visual inspection of the oil pump sprocket nut chain area.

Well took off the valve cover today and pulled a Cam Cap doesn't look bad at all in there. Didn't see any metal shavings or anything.

I also drained the oil not much to speak of on the mag drain plug, but there was sparkles in the drain pan.

Hmmmmm yea man, I'm not 100% sure but If memory serves from my own Blackstone lab report, valvetrain parts like cams tend to leave traces of iron, where as bearings more typically leave traces of lead and copper. So, I dunno if that's good news or not. You might be seeing metal traces from somewhere else if your cams and caps look okay. Unfortunately all metal traces kind of look the same when mixed with used oil and pouring out of an engine block lol. Send them a sample!

Can ticking sound come from parts moving around after oil pump nut backs off?

That last picture doesn't look great. On the cam can you catch your nail across those grooves?

I didn't clean it before I took the picture but I dragged my nail across it my nail doesn't catch.

What do you guys think, order new upgraded pump and try it? I didn't drop the pan yet I want to get the pump in my hands first because I keep the car outside, I don't want to have to bolt the pan back up while I wait for the pump to get here.

Also so what is the consensus on pulling a bearing cap on the bottom end, I understand I'd need to get new bolts thats not an issue, but it seems some other threads encourage and others discourage doing so.

That is normal wear.

If it were me I def would throw in a new pump, new oil, new oil filter & go from there. In any circumstance if the engine is hurt you would have wasted a weekend (i dont think thats half bad knowing for sure, you know?) and you would already have your new pump for you new engine since it will now be a no brainer to install that and secure the nut before installing the engine.
