If it were me, I'd throw some HDEO (Delo, Delvac, Rotella) in her for a few short OCI's, then see if you've made any progress. If not, then you're looking at either fixing the cause of the problem, or just run it til' it quits. Just up to you whether its worth the time/effort/money at that point.

All IMHO of course...

20W-50 Mobil Super 5000 should quiet it down nicely.

The tick at 2500rpm might be fixed with a PCV valve change. My 2007 seems to run quieter on QS Defy 5w-30. I wouldn't go thicker or spend the extra bucks for full syn.

The engine has been abused. If the rod bearings were showing lots of copper, chances are the mains are trashed, possibly the cam bearings too. Anti freeze will mess up bearings if there is enough of it in the sump. I would test the oil pressure with a mechanical .gauge. If the engine doesnt miss, than it cant be a very bad headgasket. What does the oil on the dipstick look like? I've had a few engines that would rap until the oil pressure came up. It was a bad thrust main in both cases. By no means an immediate death noise. Same with a bad hydraulic lifter or a wrist pin.

If you got it for free, I'd say it's worth putting an engine in.
