Good to see a community that is helpful and curious.
I am an GTV owner and have had it for 10yrs,(Xreg 2000). When I search for any information on issues with my alfa this forum comes up time and time again. What is best is that the users also explain how the parts work which allows everyone to understand why the seemingly illogical characteristics or manifestations are happening. It also makes them better placed to focus in on their issue and discard factors that may be apparent but are unrelated. Keep going with the pictures and the strip downs, they are excellent when it comes to working out if it is the same part as your own and how it works!
