No distributor. Perhaps you could rotate the Engine Control Module some.
Seriously, no codes? If indeed it is pre ignition the knock sensors could be failing to cause the ECM to retard the spark advance but that should set a code and illuminate the CEL.
Oil consumption has several potential causes, all semi permanent and expensive. If you are using oil change to a higher weight oil. Try 10W40 or 20W50.

Nickasil plated bores in Jaguar V8 engines up to about model year 2000.
This is a plating direct onto aluminium or alloy bores, around 5 to 10 thou'. It's extremely hard, effective, and used by a number of makers, notably Porche.
UNFORTUNATELY, if high-sulphur petrols are used, the plating is gradually eroded until the engine's oil consumption becomes a problem. This can happen even at 25,000mile.
Jaguar has had to replace hundreds of engines due to this effect. There is no other way to fix it.
Symptoms are a very heavy oil consumption, and another giveaway is "blow-by". When engine is hot and running at full temperature, lift the oil filler cap just a little carefully. A big 'wind' coming out indicates the blow-by, i.e. air and conbustion gasses are blowing past the piston/cylinder wall and into the crankcase, then venting to atmosphere when you lift the filler cap a little.
As I said, if this is happening to your car, either replace the engine with a good second-hand one, or get shot of it!
