I have a 2000 Accord Ex, I used the factory pcv valve, and that worked for me, been about 2 months watching and burning oil, made a trip to colorado from florida and added 3 qts total round trip, which is only about 3800 miles, there was never any smoking, I did smell it burn from time to time though. The autoparts pcv is not correct, the factory part made a difference.
Now i will try using the Honda 5-30 recommended oil, maybe it will stop completely. Thought i would share my experience.
