Thank you once again Richard.I think we can begin to come to some preliminary conclusions on the AC and cooling..

1. AIRCON If it were me, there is no question that I would put in a shutoff/bypass valve to sort the AC anomaly, unless someone can figure out this would cause a MOT-detectable increase in emissions.
The routings posted indicate that is unlikely. (famous last words)

2. T'were me, I would remove the EGR valve with a blanking plugs the US market sells for that purpose for these engines. Degassing laws primarily targeted other industries where it was, admittedly needed. Degassing automobile cooling system venting is a tad extreme. Blanket legislation can often upset reason. No one's fault, laws are hard to draft. Technology has taken us far beyond the simplicity of the Ten Commandments

3. If I had an earlier Morgan Roadster with the system, I would increase the size of the degas bottle to the later size, preferably in metal.

4. T'were me, I would quickly buy a proper radiator made for Roadsters. They will extend below the short radiators the MMC use, but after a preliminary discomfort when I began using them, I realized their extra length cannot be seen and/or be hidden at the owners open. But we should discuss rads.

You have got me deep into Roadsters! That is a first smile The CX series is many steps too far! rofl Beyond saying that I like the spec of the Plus Four the CXs are too much for me. It always takes many years (decades) to sort a design with MMC production numbers.

P.S. Discussions like this make me feel I am fortunate, enough so to feel guilty on occasion. The 2002/2003 MMC/me recreation of my destroyed 1984 was blessed by the Cdn Federal/Provincial governments as a 1984. So it was officially a reg-free classic the day it arrived at Montreal harbor 21 years ago tomorrow. Ergo, it was not subject to any rules save thosenes I set for myself. That being said, I learned to respect the trad template and make it my arena. No game is fun without boundaries.
