Specifically, blue smoke. I can rev to seven grand and no smoke. Only on initial launch after idling. Compression good, and even. Pulls out hard, no stumbles. Drinks oil intermittantly. No water in oil, but a cup or two worth of water has gone from the overflow in a month. Using 10w30 premium oil. No excessive cc pressure or dipstick ejections. Seals, or rings, or hg or vc leaking through plugs?

Thanks,
Nacho
