Curious about what is really under the hood of the Jaguar XJS?
To begin with, 12 cylinders, leave it to the Brits to call them 1-6A and 1-6B rather than 1-12. You’ll also find a whole lot of wiring, plumbing, vacuum switches and hoses. This “bad kitty” had a number of significant engine oil leaks, ran very poorly, and just needed general attention.
One of my past techs reminded me of that “If they don’t leak oil there’s no oil in them.”
While that is close to the truth, some oil is almost normal for the older British cars, unfortunately the oil was running right onto the hot catalytic converters and burning off…a recipe for disaster! Odd thing is another shop had just “passed” the car for state inspection…they sure didn’t do this fellow any favors…much longer and he would have had a very cooked kitty.
Enjoy the before and after photos, 60K maintenance and upper engine reseal.
