This is normally worn bearings and rebuilds can be quite expensive and a pig of a job to remove the TB from the car. Normally when there is a problem with it you can hear a high pitched whine, which will fade as you accelerate or decelerate. The TB has a very small amount of oil in it to start with and leaks happen, particularly the rear oil seal where the propshaft meets the TB output flange. It seems most of the TB failures however come about because of oil leaks. Even with the multi season tyres it was a dream to drive.and I drive pretty hard. I know personally having had our first real winter this year with plenty of the white stuff here in Poland. The TB, regardless of it's simplicity performs unbelievably well in snow. The transfer box (TB) got some bad press for being a bit too lightweight for the power and indeed it was partly due to this factor that Jaguar didn't go ahead with the supercharged version, and only produced one or two prototypes. I hope you enjoy the car and put some love and care back into its life.they are great motors.ĭefinitely Paul. The petrol version X Types feature a lot less on this forum because they don't have Turbo's and EGR's to go wrong like the diesels, and if i'm not mistaken the diesels were the big sellers. (fuel/air mixture, timing, emissions and a whole lot more.) It will give you a good overview of how the engine is performing and can highlight areas where some changes may be required. #DASHLOCK VALVE AND TUBES CODE#My advice would be to have a live data code reader/scanner diagnosis. However, such is the nature of the beast and power comes with a cost and i'm lucky to get around 24 miles to the gallon. Throughout the months normal motorway driving I will seldom go above 2500-3500 rpm and the car drives comfortably and with the best fuel economy I can reach. I drive my car very hard and take the revs up to almost red-lining at least once or twice a month. ![]() A new set of plugs and of course the new inlet manifold rubber seals that are required after having to remove the inlet manifold to change the rear cylinder bank (bank 1) spark plugs. #DASHLOCK VALVE AND TUBES FULL#I run it on a full tank of 98 petrol once a month to help keep the cat clean before reverting to 95 again. Also 2 downstream 02 sensors and some cat cleaner. I have replaced the manifold tuning valve seals (O rings) with original Jaguar branded ones, made a big difference to hesitation and fuel usage. #DASHLOCK VALVE AND TUBES FREE#Get underneath it and turn the prop shaft, see how much free play you can feel and listen for a clunk.Īs for the engine, the AJV6 is a great unit and on mine, which is high mileage and 2 years older than yours, I can still hit 0-60 in 7.5 seconds. Remember your car is around 15 years old now. However, the AWD system can be a little clunky because of the free play in the gearbox, AWD transfer box and rear differential. #DASHLOCK VALVE AND TUBES MANUAL#My 3.0 sport is a manual and I have never driven the auto version so have no experience of how they perform. Maybe the compponent that's supposed to damp it a bit isn't quite right?įor context, I'm not afraid to take things into pieces and I've done a few bits of ancillaries, brakes, suspension on the drive, but I've never taken an engine apart!įirst of all the gearbox. ![]() The "clunk" is a single, bass-y clunk, and coincides with feeling a slight jerk. I'm not too familiar with automatic transmissions, so not sure where to start. I'm wondering what I might be able to do to get some horses back - does anyone have any thoughts and/or experience with these engines?Ģ) It's sometimes a bit "clunky" on gearchange when engaging a new gear. It had a full service about 3000 miles ago (inc spark plugs). This is about the speed of the 2.5L V6 factory, so I'm going to guess it's lost about 40 horses in its 150,000 mile lifetime. There's a couple of things that may or may not need a bit of fidgeting with:ġ) I measured the 0-60mph time is about 8.7sec, compared to the factory 7.3sec. I've recently become the proud owner of a 2006 3.0 V6 X-type sports premium estate - the handling is quite something, though the auto gearbox seems to take some "getting used to". ![]()
