Well had my free health check at the weekend by Porsche Edinburgh and all is very well indeed !!!
They were astounded that I had rebuilt her myself and were very impressed with the work

Its nice to hear compliments from an official Porsche tech !
They picked up a few little things which I already knew about, one being a leaky window wash bottle, a slightly weaping variocam seal on the left bank and a random misfire code every now and then, which I knew about but was waiting for them to confirm the cause.
I was thinking it was an O2 sensor issue on one bank due to the data log showing it was misfiring under a lean condition on one bank. I showed the Tech the data I had and he agreed so I need to get a sensor ordered up
Pretty happy though ! I have now covered just over 1000 miles in the last week due to taking it away up north with me to work through the week deliberatly to put some miles on the new engine and I have to say I am very very happy
