WD40 and a grey (finest) scotchbrite pad .
It’s been soaking for a week with a rag over it , plastic scraper to loosen the carbon , hoovered it off and lots of elbow grease .
Still got the outside to do but saving that for when it hasn’t got loads of holes all over the place , as most of the ancillary dare coming off the engine that still has n the car
Good old WD40! Good effort, looks really clean my engine is in dyer need of cleaning, PCV splits over the months prior to it coming off the road has coated everything in sludge oil muck
