1999 2.5L V6: Blue smoke on start; engine sounds like a 2-stroke under load

Probably two different issues. My guess (on digging around) is:

1. Bad valve-cover gasket for the blue smoke; and,
2. Something manifold-ey for the noise.

The car's eating a quart every couple of thousand miles. I'm pretty sure I replaced the valve cover gasket due to oil in the spark-plug wells; perhaps 60 or 80 thousand miles ago.

Alternately: the blue smoke could be the "PCV" thing or valve stems. Neither of those sound ... good.

Valve cover gasket won't let any oil into the cylinders; it doesn't come anywhere near the combustion chamber.

Doesn't sound good, that's for sure. I'd suggest a compression test.

The car is also leaking oil onto the ground. Kind of like a mobile superfund site.

Sounds like the engine might be done .... complete a compression and leak down test.
