Is my engine dead?

that makes sense. I didn't think it would be that dramatic though.
maybe what i'm hearing is the chain slapping the sides of the cover?...

I wonder if the oil pan comes off easily.. I remember having a B150 conversion van and the engine was so gunked up with crap that the oil pressure would drop. I could get the pan off without too much hassle while the engine was still in the van. I ended up buying a long block after pulling the pan and seeing all the crud up in the engine.
