The engine needs to go through cycles of warm up and cooling off.

Yeap I agree, only way to get to the bottom of this is start tearing the motor back down until, the problem is found. I had a motor I built myself, It was using oil but didn't smoke. When I finally tore it down, I found I had a broken ring on #5 cylinder. That doesn't cause lifters to start tapping and loud banging noises.
I mean if you already have that much into it, you need to find out whats wrong. But if you decide to wash your hands of it. contact me, I'll come get it.
