What are the problems with a Jaguar V8?
The problem with the early Jaguar V8s is two-fold. First, the Jaguar V8 runs cool and is very under-stressed. If the engine is not allowed to heat up to full temperature, condensation or water can build up in the oil.
How old is the V8 engine in a Jaguar XJ?
Over the engine’s 12-year lifespan, Jaguar was constantly improving the AJ-V8 with better parts and software calibrations. However, in some cases, the changes in the engines were not consistent with the XJ, S-Type and XK in those same model years.
What kind of engine did the Jaguar 4.2 have?
At best the 4.2 litre Jaguar/Daimler engine block could be described as suspect and its quality further declined throughout its production. It was designed in the early 1960s to give more torque and better low to mid range performance than the 3.8 litre engine, which it genuinely did.
What is the VIN number on a 2004 Jaguar XJ?
Jaguar has a strange way of designating the model year. A 2004 XJ might be considered a 2003.5 XJ if the VIN number falls within a certain range. Also, changes to the engine might not correspond to a model year, but rather with a VIN or production date stamped into the engine. So, always have the VIN ready when ordering parts.

What causes a Jaguar 4.0 liter engine to crack?
On the early V8 models, the plastic guides can crack. This causes a lot of noise, vibration and jumped timing. The cracking of the guides is often attributed to neglected oil changes and a bad design. If the engine has a history of overheating, the guides could be damaged.
How does the VVT work on a Jaguar?
The system operates over a range of 48 degrees and is advanced or retarded to the optimal angle within this range. The engine control module controls the VVT using engine control signals pertaining to engine speed and load, and engine oil temperature to calculate the appropriate camshaft position.
What makes a Jaguar 4.0 Liter V8 Rattle?
If the unit or stopper pin is damaged, it will cause a rattle during startup. For its 1998 and 1999 V8s, Jaguar used Nikasil coatings on the engine cylinder walls instead of liners. Nikasil is a very hard, friction-reducing material made of nickel, silicon and carbon.

Can a Jaguar S-type thown go on the highway?
Crusing home on the highway going about 70MPH, not accelerating nor coasting, just maintaining speed. The engine basically shut down, and I had to pull onto the shoulder, it was very dangerous and frankly, it freaked me out.
How often do you change the engine on a Jaguar?
On almost all Jaguar V8 cars, there were at least five different engine control unit (ECU) updates and calibration changes. Some of these new calibrations were for models that were five or six years old. Most of the updates concern poor idle quality, engine pinging and catalyst efficiency codes.
What kind of material does a Jaguar V8 engine use?
For its 1998 and 1999 V8s, Jaguar used Nikasil coatings on the engine cylinder walls instead of liners. Nikasil is a very hard, friction-reducing material made of nickel, silicon and carbon. Porsche and other manufacturers have used Nikasil coatings with very few problems for more than 25 years.
