VVT solenoid actuator oil leak UPDATE

[mickeytee]

If you have leaks you need to replace the magnet unit compete.. The plug is just so you can insert the gm tool for alignment. You do not want to remove the vvt unit from the camshaft. Without care you can change the timing. If your oik has been changed thet are oil feed and dont require any cleaning. There are several write ups on how to change the vvt solenoid magnets. You need to again follow proper procedure to align them. you do not want to remove the center plug.. Not sure what you found listed as that plug. but the ew ones come with a new plug

If I were you I would change the the whole thing, they are not that expensive, I listed the part number earlier in this post. If your car is running ok I would leave the cam alone, "if it ain't broke"... No relearn needed.
