Have some one crank the engine with the valve cover off and try to listen and look around and see what you find (get ready for a oil shower, it's not that bad). If you really can't can't get an idea of where the noise is coming from, fuck it / try fishing all the metal particles you can get with a magnet. Oh and while your in there look up how to remove the 2 chain guides you don't need(one of your's went poof). Then drop the pan, clean it up good and look to see any signs of damage. Slap her back on with a magnetic oil drain plug. Buuuuuut it sounds like there is a under-lining cause to why she won't start........ check compression (if low do a cylinder leak down test) GOOD LUCK!
edit* sorry for writing everything in a fucked up order. Start with the easy and work from there!
