Good thoughts and ideas.
I previously switched plug wires and noted no change, so it is not the plug wire. Checked the distirbutor cap and all appeared in order. Don't think it is an electrical problem. The quart every 300 miles or so leads me down the
oil path rather than the fuel path.
The point about the
oil seal not accounting for this amount of
oil consumption is well taken. Perhaps a intake manifold gasket is a more likely culprit.
I am still mystified about the lack of blue smoke in the exhaust or the lack of oily residue in the right side pipe.
I use 20W50 Valvoline racing oil. No synthatics.
