What Jaguar problems ... And the solutions found. The two things that recently played are very different. But we just put them under 1 head. Otherwise it seems like the Big Cats are very problematic ...
And they are not.
Jaguar V12s are just as reliable as Mercedes Diesels. Only they can't manage without sparks.
The 1974 Daimler Double Six from Reader Rob Man did not spark on cylinder number 3 and only faintly on the rest of the dozen.
A new rotor arm, distributor cap, spark plug cables and spark plug caps did not provide the definitive solution.
The venom turned out to be in the plastic rotor disk. It has 12 ferrite rods, and one of them wants to sink and get lost.
Then the relevant cylinder receives no - off almost no - signal. And therefore no - or almost no spark.
XJ40s have now also become cherished Jags. They have, as has been shown a few times in the meantime - a unique point of attention: the muffler under the trunk can rust at the top. Then the hot exhaust gases heat the floor of the car, where the sealant melts between the seams, the glue of the mats.
The floor is then fired hot until the case starts smoldering and smoking. And after smoldering comes on.
With 'the knowledge of today', similarly, some fires that in the past were accused of battery or wiring problems could actually have come through such an outlet leak.
... and then this story must also apply to the X-300s. Yet?
