Okay, it looks a lot worse than I remember. Regardless, the journals are going to be polished.

Just went thru similar ordeal on a newly purchased Dodge 886
Low miles under 40 thousand engine popped as u throttled it up
Well after removing intake found a wipped out cam lobe so being truck is very heavy I ordered an Isky towing cam and luckily all went well
I soaked lifters used Isky lube with cam and dumped a bottle of stp over cam before putting intake on
I guess THIS TIME luck was on my side about 500 miles on said cam and zero issues also purchased Summit brand lifters from a member .

The shiny area in the middle seems to indicate a very thin oil film......

You nailed it lots of off-shore junk also sold in the US , he could have done everything spot on and still this happened.
Wow, sorry that happened to you. I guess it's been said before in this thread, it doesn't really matter why it happened at this point - we just know it happened and now it's time to fix it.
Okay, I didn’t doubt anyone who said I needed to pull the engine apart, but since I did, here’s some proof I found that says it was indeed necessary. This is the #4 main bearing, and you can see a fine silt of cam and lifter material that has made its way throughout the engine. That **** is EVERYWHERE.
I’m confident that if I didn’t break everything down to get it clean, I’d be sealing my fate for either another failure right away, or at the very least, premature death to the engine.
The crank is at the machine shop being cleaned and polished, in the meantime I’ll be cleaning the block and prepping for reassembly.

Thanks. The way I see it, why ask for advice if you’re not going to follow it?
I’m also trying to see the silver lining here, since I’ve been wanting to paint the water pump and clean up some other things. I also found the source of my exhaust leaks in the process, so I think it was a good decision all around to pull the motor.

The silver lining is you're smart enough to fix it right this time and not do it over again down the road lol
I certainly hope so!
