Hi,I need help please 🙏🏻 I have a 2007 Volvo XC90 V8 and there are 4 sensors under the engine cover. When the car starts warming,the one at the back ( by the windshield firewall) seem to be dripping oil out like crazy and drips on the manifold and cause a lot of smoke and drips a lot on the ground.
i thought they might be cam sensors,but they all only have 2 connectors, and not 3 and there is a silver ring over then which I have removed,but then have no idea how to get the sensor out.
I'm thinking it might be the O-ring on it
Please help me!
I thank you all

 

Those are your VVT solenoids. The valve cover needs to be removed to remove them. Or you can remove the 10mm screw holding the metal ring on, pry out the seal and replace it.
