I'm please to hear you've solved the fault light. Your code reader looks the same as mine, just a different name. That "inspection port" is a good idea.
One question, did you need any new gaskets for the job or are the seals "O" rings and so could use them again?
The diagnostic reader looks similar and certainly seems to function in the right way - I saw a very positive review on the Tube, so I thought it was worth a punt - and it was available over the counter, locally. I was guilty of impatience, wanting to get it sorted in good time for a long trip away (including a little track session at Bicester) at the back end of next week.
The seals are very much reusable. Fancy green O rings in recesses (see from 15 minutes into the video) - careful cleaning of the mating surface and the seals before refitting, not that they were very grubby anyway. I refitted very much guided by a YouTube video
Particularly regarding the torque settings mentioned (20 NM for the manifold bolts and 10 for the throttle body - those settings certainly felt about right for those type of fittings). There's a bit more space around the engine bay in the Morgan than in the Escort featured in the vid - also connections and the lower manifold bolt are accessible from the top only for us, whereas the guy in the vid accesses some from below.
The 500ml can of Holts EGR cleaner was plenty for doing the valves. I also used some for cleaning the throttle body and the manifold, spraying into all the holes and swooshing it around several times - to get rid of any residual oil lurking on the internal surfaces. There's still a small amount of cleaner left in the can. It was considerably cheaper than some of the seemingly similar products such as Seafoam or CRC. It smells a bit like cellulose thinners and I was careful to avoid getting it on my hands.
