Oil Seeping Around This Thing?

Oil Seeping Around This Thing?
What is this sensor called and does it come out?
I have put about 2500 miles on my 2004 XK8 since an engine shampoo and noticed oil seeping around this rubber seal in the valve cover. I cleaned it of but did not want to try and pull on something that should not be pulled on to see if it could cleaned up and stopped from leaking. I wonder also if it might represent a crankcase vent system leak which might account for my occasional P0442 error code. Evaporative Emission Control System Leak Detected (Small Leak)?

Those are the Variable Valve Timing Solenoids (VVT) and they are not removable from the top HOWEVER the seals can be pried up with a screwdriver and ARE replaceable from the top. The part number is: NNE2622BA, about $10 each. Be sure to clean the dirt off the solenoid when replacing to avoid contaminating the seal.
That is not the source of the EVAP leak though.

Take them back to the dealership and order them online from motorcarsltd.com. I did so in March 2013 and paid about $27 for both, including shipping. Even with shipping to Canada you'll save a bunch of money by going this route....
I believe the proper part number for the 4.2 engine VVT solenoid O-ring seal is AJ82856 so you may want to double-check before you open the package you've already purchased....

FWIW I used an OEM part when I replaced mine. Saving a few bucks on something that prevents oil leaks is not worth the risk.

Just make certain that you wipe the area squeaky-clean after removing the failed seals and before installing the new seals. Any trace of old oil or grit can cause your new seals to leak prematurely. These things bake in the engine bay and my experience has been that regardless of where I source them, they turn hard and brittle and begin to show small surface cracks within 2 to 3 years. Sure wish a supplier could offer a set made out of much more durable and pliable material....

FWIW I think its the participants that are great, not the platform. The site itself has been eroding for a while now. All from the desire to be more profitable than helpful.
