@WD, yeah, I don't watch AI voice overs too much if I can help it. Sometimes I'd rather than hear those rather than someone stumbling over words or poor audio, but just barely.
I posted because I wanted to mention the architecture of the Jaguar I-6 in its few iterations. The bottom end, if kept up, seems to never need attention long after something needs to be done on top. Even the cam and drive is plenty robust. Induction has been a bit tricky all along and although it got much better when Bosch entered the picture, that also came in the period when emissions were at the same time the concern. So coil packs and other sensors were really the only repairs that were needed. Or call it maintenance, but keep the crankcase full and all the trouble was above that if there was trouble
Pretty much all done with cars these days but if there was ever a project left to desire it would have been using the classic XK engine (1948-1992) or stripping off the injection of the later AJ6 and AJ16 motors and installing Webers with possibly a magneto ignition.
Using one of these in a lot of cars I can think of would have been a hoot.
