Replaced the AOS, I didn't take as many pictures as hoped but have some.
Behind the throttle body within the intake areas which I could access, there was a good coating of oil all around, so I took that as a buggered AOS.
I'm not sure what the fuss was about in regard to this job, it took 3 hours but it wasn't a challenge, the hardest bit was getting one of the pipes off from the back of the AOS, I couldn't get a squeeze on the clip. Dead easy really.
I haven't used the car much since doing the job but on the times I have, no smoke. My oil pressure gauge is working now but it seems very slow to respond, once the pressure goes up, it takes a while to sink back down so I plan on changing that, after doing some googling, it seems they dont last long..
So, anyone wanting to do this, easy job, just give yourself 3 hours, a chair and a beer and crack on.
Just removed airbox, a/c pump moves to one side, PAS bottle and then you've got access.
Found a ***** ton of leaves which I hoovered out.
Old AOS
I cleaned all the pulleys and other bits and forgot to take pics of the finished article! Doh!
