With the pressure now off I took a break and ordered some more parts.
First was some new petrol tank straps as they looked in a bad way, came across some stainless steel replacements so went for those, also replaced the fuel filter at the same time as I bet its never been changed



The sump was also badly corroded so a new one was fitted before putting some nice new oil in.
Needed to do something with the exhaust so bought a new Direnza stainless steel system which was fitted with new powerflex mounts





Now those emissions:
Reading the failure sheet a bit more carefully the co2 readings were good but the lamda reading was high, on investigation it would seem the engine was running lean. As the engine warning light was still on I thought about reading the fault codes so bought a £13 reader, this runs on a pc with windows 8 or older (not 8.1) so I dug out an old laptop and installed win 7 on it



The fault code was "engine running lean" which could have been a fuel blockage or air leak, in my case it was a split pipe on the back of the inlet manifold, which was quickly replaced by one from the 5 door

The wheels were then changed for standard st170 et49's up front and a pair of OZ et42's on the rear and driven back for another full m.o.t which I am happy to report it passed with no problems
