Excellent description - and like all complex engineering solutions, a real b*gger when it goes wrong.
And things do seem to go wrong on them at high but not stratospheric mileages ie. under 100K miles.
And, while my 2011 BMW with double vanos was recalled last summer for 13 hours investigation and remedial action on the vanos (at no cost to me) I'm not convinced Morgan would take the same approach!! And they returned the car with major engine issues so it had to go back again. Happily ok now...
But the engine is a peach and works seamlessly when on song. I don't think they like very high g forces in any direction for long so don't do any loop the loops!
