I recently bought a CR-V 2004 with 119,000 on it and have the same concern.

 

Can either of you post photos of your leak?

 

Theres oil all over the passanger side rear so im not sure what you want me to take a picture of?

 

How well did you clean it? If you just wiped it you may not be able to see. I'd get a can of brake clean from an auto parts store and spray the crap out of it. In fact, get 2 cans, maybe even 3 if it's really bad. Valve cover gasket and oil pan gasket would be my first two suspects. Check the timing chain cover, and anything else you see (sensors, oil lines, etc.).

If you are leaking oil check your PCV. If this gets stuck closed it can cause your crankcase to pressurize forcing oil out of the the spots mentioned above. I would change it anyways if it's the original they are usually cheap and easy to swap out.

 

One place to look is around the spool valve, there is an o ring on the top and an o ring type gasket/filter where the valve mounts to the head. In the picture they are #5 and #17. On my old Accord that was a pretty good leak.

Ok thanks guys i will try cleaning it really good and try that

 

Follow-up: I had a shop replace the oil pressure sensor with an aftermarket part.
The leak stopped ... but a month later my oil light came on as a steady flicker.

Took it to the Honda Dealer to diagnose it. They tested many associated things. Changed the oil Filter again.
Finally they decided to replace the aftermarket part with an OEM sensor.

Problem solved and 3 months later all is still fine.

 

Did you use either Hight temperature thread sealant or Teflon tape on the tapered threads of the sending unit?

 

I had a small repair shop install the aftermarket part, so I have no idea if they used sealant of tape. Are you saying that it might have made a difference in avoiding the malfunction ?
