Just received a call from the Dealer.  O2 sensor checked out, but is running
very close to the edge, but they want $170 for each, probably plus labor..
Where did you see $120-$130 price range ?
Also, the vacuum hose needed replacement, seemed to have been heavily
damaged by the engine oil leak.  Dealer contends "surging" was caused by 
that.  One thing for sure, the idle will be much smoother now.  Probably
will need to replace O2's as well.

Don't know what kind, I wasn't the one who replaced them.  I am also
trying to drive it with the ABS disabled, but don't feel a big difference

Denon ?  How much ? What does it have ?

Surpsingly, this valve gasket leak is not that expensive to fix,
dealer quoted $228 parts&labor.  Probably easy to get to...
