17z bathroom sink faucet slow leak.

[Feather17z]

I have a new 2014 17z with a slow drip on the bathroom faucet. It is slow, but fills up a half gallon tub in about 4 hours...
I talk to the dealership and they told me to add Vaseline to the o-ring and see if that helps, before we do a warranty exchange.
I removed the faucet handles, then unscrewed some brass ring on top of the valves....but then what? Everything almost looks like it is one piece plastic valve, and I don't see any obvious way to unscrew the valve to access the o-ring....
Has any one ever have this problem and accessed the valves? It looks like some pretty cheap plastic assembly and was worried to apply too much force to it without knowing what I was trying to remove ( or if it was even removable...)
Thanks

In most faucets the 0-ring is used to prevent leakage around the cartridge. Vaseline will make it swell so if it's removed it'll be more difficult to replace. What may need replacement is the seal in the faucet body. There's usually one for hot, one for cold. If anything needs lubrication use either plumber's grease or silicone lube.

Have you checked the water pressure when the faucet's leaking? Have you contacted a different dealer for a second opinion?

ok guys,
I thought I would give an update on the problem...
I took apart the faucet again, removed the handles, then the brass rings holding the valves together and ...yes,this time it was very easy to take the 2 valves out by pulling up on the handle screw...( I don't know what I did last time that I couldn't take these appart...).
Once the valves were out, it became very obvious that there was a little plastic protective sheeting in one of the valves on the bottom, preventing the valve to sit properly on the oring....removed it and now no more leaks...easy fix!
