Re: Jaguar engine

I may not be wholey accurate here but no doubt I will be told if that is the case....

Ford bought Jaguar in 1989. Reliability increased dramatically.....(I have an '88 XJ-S and can testify to this...)

However some very modern jags are nothing more than re-bodied Fords - for example the X-Type is wholely based on the Ford Mondeo - same chassis and frame......not sure about the engine....

Re the "sealed" engine - I think only some american cars have this - your Jag certainly does not have a sealed engine and to bear this out Cylinder Head Gaskets are a common item to be replaced on Jags of this era.

Regarding whether it is necessary or not personally I would have thought only if compression was below par and/or you were buring oil - mileage alone I wouldnt use as an excuse to start dis-assembling the engine - mine has 116,000 and doesnt burn a drop - guess it depends how it's been driven.

Neither the Mondeo nor the X-Type have a chassis, so that isn't quite right - and they certainly don't share the same floorplan (the Mondeo has a longer wheelbase). What they do share is about 15% of the "unseen" components - suspension components, electricals, and the FWD portion of the drivetrain. This is not necessarily a bad thing - for one thing, the Mondeo has superb handling, and the Ford electricals are certainly better than anything else that Jaguar ever used.

OK, you fixed up an old worn out Ford. It WAS worn out THAT's why its performance was improved by the new piston rings for they restored the engine's compression back to its original specification.

Before you do anything to the Jaguar you ought to know the facts. The engine's compression can be checked with a compression tester and compared the the manufacturer's specifications. If it falls within those specs. you should leave it alone. Any time an engine (or transmission) is opened there's a good chance for errors to occur and errors can be costly to correct. So if its OK, leave it alone. Drive it respectfully and maintain it well and the car will serve you well.

If you seek a project car buy a wreck for there's little financial risk when you make a mistake.

It looks like a Taurus to me.

Hey Ron, fancy meeting you here... :)

The Jaguar V6 shares the same block as the Ford Duratec (or did initially - they have probably tweaked things along the way), but the heads are Jaguar designed, and completely different.

Hi Graeme,

I'm told the main bearings are also larger, pistons different design and some sort of "cradle" assosiated with the mains and crank. Must try and get a look at one, one day.

Cheers mate,

Ron

Ron is right,

however, if the car sounds good, and doesn't blow oil, and clatter a lot, leave it. If there are no oil leaks around the plugs leave it. If you really desparate, gat a compression check done, if is in specs leasve it. The trick with any aluminium engine is to have regular oil changes and make sure the coolant is the correct one. Ensure you service the readily available bits as per the service code and you should be right. I had a

1987 3.6L Daimler which I sold at 308,000km and it still ran like clockwork. I now have an XJ 3.2 Sport 1996 six cylinder. Excellent car, has enough power and is really fun to drive, has never missed a beat and for a car going on 7 years and going on to 90000 km, is trouble free and still looks like it came out of the showroom. I love my Jags. Keep the service regular and above all make sure you have a good independant Jag specialist to maintain the difficult bits for you - the right guy will save you money and look after you and is not more expensive than a regular car.

The best thing that ever happened to JAg is that Ford bought the company - they are much more reliable now than a Merc - just check the alldata TSBs.

LOVE my JAG

Bill

Just for kicks, go to

and look at all the divisions of Ford - Jaguar, Volvo, Mazda, Land Rover, Aston-Martin. All of these marques are Fords. And here's a bit of trivia - Cadillac was originally a Ford product until ole Henry split.
