DIYer error...I had initially set out to replace both valve cover seals and I had unplugged both eccentric sensors and drives. When reassembling, I plugged back in both eccentric motors but only the passenger side eccentric sensor. The drivers side eccentric sensor plug had fallen back into place and appeared "connected" and I hadn't triple checked it because "I didn't work on that side." My mistake. Tonight, with a fresh mind, I quadruple checked all sensors I had touched, including the driver side eccentric sensor. To my surprise it pushed further in and clicked...fired it up my X and it purred like new.
Everything seems to be resolved:
- no more oil leaks!
- no more clouds of bluish/white smoke on acceleration from prolonged idling
- no more oil entering the intake manifold via the PRV
- idle is now very steady (varies smoothly between 689-703 (w/AC on) according to the scan tool), no more surging!
- opening the oil filler now causes the engine to stumble as it should
- engine is very strong off of idle
