1985 Jaguar Vanden plas problems

Common 1985 Jaguar Vanden plas problems

The 1985 Jaguar XJ6, particularly the Sovereign 4.2 litre model, has been praised for its smooth and quick performance, as well as its reliability. However, there are some common issues that owners have reported.

One of the most common problems is the rebuild of the engine after a certain mileage due to the engine starting to use oil. This was the case for one owner who rebuilt the engine after 90,000 miles because it was starting to use oil, though the oil pressure was still up in the 60's at around 70 mph. This issue can be attributed to the age and mileage of the vehicle, and regular maintenance is crucial to prevent serious engine problems.

Another common issue is rusting through of the gas tanks. This was the case for the same owner who had to remove both gas tanks and have them refinished due to rusting. This issue is common in older vehicles, especially those that have not been properly maintained or stored.

The A/C compressor is also known to have problems, with some owners replacing it with a later type to avoid issues. This is a common problem in older vehicles, especially those that have not been regularly serviced or maintained.

The three-speed automatic transmission is known to be long-lasting when maintained with fresh transmission fluid on the regular basis. However, those that have not been maintained with the regular 15,000 miles fluid and filter change may fail early

. This issue highlights the importance of regular maintenance and servicing of the vehicle.

Head gasket failures are also common over a hundred thousand miles, and replacing a head gasket can be a challenging task

. Oil leaks are also typical, with most gaskets being easy to replace except for the oil pan

. The USGI or Series 3 that are emission equipped are prone to having the taper guides and aluminum head coming loose and crashing around the inside of the engine, which is a heartbreaking experience for any Jag owner

In summary, the 1985 Jaguar XJ6 Sovereign 4.2 litre is a smooth and quick vehicle that is very reliable, but it is not without its issues. Regular maintenance and servicing are crucial to prevent serious engine problems, and replacing parts such as the gas tanks, A/C compressor, and head gasket may be necessary over time.
