Metal in oil

Do you plan on removing engine to take to rebuilder? If so remove the valve covers and take pics. Lots of knowledgable people that can help you.
There are nuances to these engines, make sure this engine rebuilder is knowledgable on mopars.
Maybe post a thread looking for someone in Spokane area to come take a look at engine for you? Cost of a few beers and lunch. Make a new friend and gain some insight.
