No oil pressure on my 340 :-(

What a mess

Yep, and with the silver "paint" showing in the oil, this thing needs to come right apart and get flushed, or some of those metal particles will cause a nice, big failure given time. What a giant PITA!

Honestly I would, but there are no markings on the rear main bearing or seal, as well as no metal on the windage tray for what it's worth.

You had your eye on the oil pressure during the break-in run right ?

Cut your oil filter apart and look inside!!!

Yep! It wasn't until the last start up that I had 0 pressure and you could here a slight lifter knock. Shut down immediately

Do your self a favour and take the engine apart as others here have suggested, the amount of metal bits in the bottom of the oil pan is NEVER good news for long engine life. The metal will always find it's way into the vital engine parts, or small oil passages if you don't clean it properly.
Look at it like it's gaskets and mental reassurance now or likely everything later and later never happens at a convenient time.

Sorry to hear the news.  You will get it figured out.  Take your time and hopefully you won't have any major problems.
