On the left side of the engine, the VVT Solenoid Seal is easily accessed, On the right side of the engine the intake resonator and possibly the air box must be removed and Mass Air Flow Sensor electrical connector must be disconnected to access and replace the seal.
The seal is a shared part among many Ford, Lincoln, Jaguar and Land Rover engines. In my video, I use a Jaguar part. I purchased this part on Amazon for around $10, it can be found here: https://amzn.to/2HShucc The seal is sometimes called a Rocker Cover O-Ring. The Amazon parts fitment verification tool will say this part does not fit a Land Rover LR3, you can disregard this warning.
Some of the possible part numbers for this seal are AJ82856 and 2W9Z-6A545-AA.
If the area around the VVT seal is dirty, it may be prudent to spray some simple green on a rag and wipe down the area, you do not want any large particles of dirt to get into the engine when you are removing the leaking seal or installing the new seal.
To remove the old seal, simply disconnect the electrical connector and then take the small flat blade screwdriver and gently work it under the lip (see pictures below) of the seal and pry up and then remove the leaking seal. To install the new VVT seal, take some oil from the old seal and lightly lubricate the new seal, then slide the seal over the solenoid and press firmly into place. Make sure to fully seat the new seal on the valve cover.
The picture below shows the old VVT seals after being removed from the LR3. The bad seals are leaking oil on to the valve cover.
