AAV replacement - part II

As per previous blog: http://erwinxjs.blogspot.nl/2016/09/auxiliary-air-valve-high-idle.html

Now the follow up. The parts arrived earlier this week. The hose appears to be China made :-(


 The gasket however is German made :-)


The AAV is likely made in England by Lucas:


Here the air intake in a cold state, it's not entirely open though.


And hereby a test I carried out to check if the valve was working in hot and cold water. It's not exactly an entertaining video to watch, but it shows the functionality:






Today it was time to mount it and put everything back together


And yes, it worked perfectly, this was only shortly afterwards. When fully warmed up and after a small test drive it was steady at 800 RPM.


What a huuuuuuge difference this makes. It drives almost perfect now and I did not even had to adjust the AAV. On to the next job.
