The right solution as you say is to replace with a more modern module, so that may come at a later date, for now I cant justify the cost when I still have a list of more important jobs.

Out of interest, what makes you think you have a vacuum leak?

Hi, i have an 07 4.2SC. It was fairly poorly cared for before i got it. I have been chasing a misfire on cylinder 8 since i got it. Changed all the usual stuff but still it persisted. Kept getting the misfire code and both cat efficiency codes. Obviously the engine light was a daily occurence. Like you my cat 2 sensor readings were jumping all over the place.

David, thanks your comments made me think, if leaks are uncommon/unknown then why have I got an issue? / have I got an issue?

Have you checked what your fuel pressure is? |

I managed to do the Supercharger oil change that I promised the car since I bought it.
Here is a shot to show the difference between old and new. The only worrying thing is that this is after only 15k miles so I intend to do this again at the next engine oil service in about 5k miles. Getting the plug back into place was very difficult, I asked my wife to give it a go as she has small hands, but that didn't work and as my hands were too big to get access, I removed the bolt holding the front of the Throttle Body Intake down and as it has a rubber collar at the Throttle body end I was able to lift it enough to get my hand in to insert the plug. Otherwise I would have removed the Throttle Body Intake, an easy job but you need to remove the Plenum Chamber to do so. So an easy job made difficult by access issues Personally I would change every 20k not 50k as others including the oil suppliers recommendation of 50k, the cost compared to a rebuild/replacement of the supercharger makes it a no brainer!

I use Microsoft OneNote to keep a history of servicing, parts and specific jobs that I have done or need to do. I also add links to my calendar and Microsoft ToDo which sync to my mobile and other devices. Range Rover 4.2 Supercharged 2006
