I had a 360 turned up considerably. The design of the heads with heat crossover etc makes them run hot. The valve seals don't seem to last too long.
I always used bronze valve guides and Moroso valve seals with its own little spring wire tension on the high temp tolerant seals.
Some of newer engines use only 2 ring pistons and even if three low tension rings.
I don't see a drop on the ground, or on the motor, or out the exhaust but it uses a lot of oil.It's 5.4 Ford.
the valley cover gaskets on the 360 leak quite often, especially if the heads have been planed or cut because of warpage and no adjustment to the metal of the manifold or one piece gasket valley cover.
Sine you don't see any signs of useage other than disappearing oil, you are probably getting oil around the rings and burned.
Synthetic oil is thinner and usage will be more than with old dino oil too.
