V12 Concern

Q As Asa US owner of an early V12 Jaguar XJ-S, a recent video caught my eye. I don’t know if you follow ‘Harry’s Garage’, but he posted this recently: https://youtu.be/ DQdheMlLmB8.

It covers the necessity to totally replace the original fuel injection and ignition system in order to simply achieve a reliable car, consistently running on 12 cylinders.

Is the original set up really that unreliable and do we really need to spend a pile on a new system? I have always held out hope that someday soon the world will understand just how fantastic V12 engines are, and they will be hugely sought after – V12 XJS’s commanding E-Type prices.

Forgive me,
