I hate to say it but you need to take that motor all the way down. My cam and lifters in the "old" motor took out the mains, the metal had to go somewhere.
A good friend of mine is a nationally known engine builder, he confirmed the oil situation. BTW, some folks will tell you to use Shell Rotella T motor oil, it no longer has the wear additives either. Use the one of the Engine Oil Supplements I mentioned.
