I have fitted a steel head which has immediately cured the issue and will ponder on a suitable repair that will ensure leak free running. The other original I have gave superb performance on the Chummy until it started to crumble…
Citroen 2CVs and CXs both have a habit of occasionally blowing sparkplugs out of their heads and leaving no thread in the head.
These are 14mm short reach plugs in an aluminium head.
They can be helicoiled and Citroen specialists can do this with the head in situ.
How do I know? It's happened to me twice, once in each variety of Citroen.
It's easy with practice!
I had a 1934 4-seat tourer on which the flywheel taper had been badly machined. The flywheel key sheared regularly.
When this happened I was able to remove the engine, replace the key and have it back in in 3/4 hour. There were no unnecessary bolts or nuts. eg radiator only held on by its hoses and the bonnet. Minimum number of bell housing nuts etc, and of course, much practice.
