Did you replace both CCV valves or just one? You really shouldn't have blown rings this early on with this engine...maybe head gasket? Does the blue smoke pulse like it might be on one or two cylinders, or come through on what seems like every cylinder's firing? How fast are you losing oil? Losing any coolant? Any oil in the coolant? Any coolant in the oil?

Get a compression test done. If a cylinder is found to be below spec do a leakdown test. That'll pretty much pinpoint the problem.

Usually, yes. Valve seals will produce smoke either upon startup and disappears shortly after, or smoke upon deceleration because vacuum is at it's highest and oil is drawn through the seals. It wouldn't be a head gasket or burning coolant because the smoke would be white.

I had the same problem. It was the intake manifold gasket. All repairs including new plugs, oil, plug seals and labor was about 2500 and 2-3 days. Best of luck.

I was getting small clouds of smoke when i would start it after work, and only after..So I took it in and was told it was a sensor, (phew) but the cpu would have to be flashed after instal and only the dealer could do it... So the dealers hours suck so i have to wait. One day on the way home from work I floored it and a HUGE cloud of smoke came out and warnings came on...engine, exhaust... so it took it to the dealer and after a days of waiting and test after testest I took it from the dealer with nothing fix. The wanted to a compreshion test ($700) lol. But the car was misfireing, and lot of build up on my spark plugs( so some oil was bing suck into the combushion chamber). So took it somewhere else and it was the gasket. Which is a common problem with this car from what I read. But since the repair no problems.
