I wouldn't drive it with either of those problems. The poor motor sounds like a Diesel, it does indeed sound like the cams are not getting properly oiled, especially if you are noticing heavy lobe wear. If that is indeed what is happening, then the motor is wearing out by the minute.

The steering, gosh I dunno. But that much play would have me too scared to drive, especially if it sounds like something is getting loose and could let go at some point.
