Oil is disappearing, engine stumbles. ???

[FlyBono24]

The car doesn't drip oil at all, but when I drive it just disappears. I don't know if it's burning up (I don't see any smoke or anything) or if it's pushing out of the bottom somewhere.

It also stumbles at high speeds.... wtf is going on?

Oil Gnomes. Just like underpants Gnomes, but they work for Halliburton. High speed miss... oil gnome getting caught in the oil pump.

well, if it isnt leaking, then it's burning. valve seals or rings is likely the culprit. if your plugs are fouled enough from oil being on them, it could create a miss.

I replaced the PCV valve.... didn't know if that would help out.
