    The x308's have a trick to get to that rear spring pan stuff without risking your digits. If I remember right it goes like this:
    -Remove calipers and wheel speed sensor harness, and hang on body somewhere (bump stop?)
    -Slightly preload lower wishbone with a jack
    -Undo 4x nuts that hold upper spring pan to frame
    -Remove shock lower eyelet bolt
    -Remove preload on lower wishbone, allow it to drop
    -Rotate halfshafts so that the U-joints allow for the most flex
    At this point you should be able to pull the vertical link down enough that you can pull out the upper pan, spring, shock all together out of one side. You might need to undo the rear truss to let the A-frame pull away from the frame a bit for that extra clearance. That's how I did my shocks+bushings job, never needed to touch a spring compressor, and relatively low risk. Not sure if the x300's have changes in the design which prevent this trick from working.
    That center support bearing (again this is x308 experience speaking) isn't sold by Jag parts shops or dealers, as far as I remember, but you can buy the bearing direct from manufacturer. Powertrain industries 3080-25 (again that's if the x300 uses the same driveshaft, I know it's similar but maybe not identical)

      My thoughts exactly. That's why I ALWAYS do plugs by hand never with a power tool. Changed hundreds of plugs in my time by hand and never any issues and it stands to reason if the person had done it this way Mr Wizard wouldn't be having this problem now. The Jag V12 is an interesting engine,you just need the proper knowledge to repair and maintain it.

    Jag V12's can be a PITA to access sparkplugs! I also sympathize with the infamous "we can order it for you" phrase dealing with auto parts vendors, can sometimes take weeks instead of days.
    Firing order is 1A, 6B, 5A, 2B, 3A, 4B, 6A, 1B, 2A, 5B, 4A, 3B. Barrel of fun! I like our '52 Jag XK120 w/3.4L inline 6, plugs are all right on top and can be changed in about 15 min.

  • @nicksauer6749
    @nicksauer6749 Рік тому +3

    You may have missed the underlying cause of the stripped spark plug. These heads have recessed spark plugs which collect sand, grit and oil. When the plugs are removed the grit falls into the plug hole. Then, when the new plugs are installed the threads are destroyed. Everything is OK until the next mechanic comes along and removes the spark plug. It is vitally important to blow off any debris before removal and carefully clean the spark plug seat before reinstalling. As far as the spring mounts are concerned, you may have replaced them the hard way. For many models it is straightforward to put the car on a lift and lower the entire rear suspension assembly onto drums as a single unit. Then, they are very easy to work on. Hope this helps.

    I'm a Jag fan Wizard so you have my thoughts. I have always avoided V12' because power is not my ego game. Anyway your model Jag is easier to get to and work on than the other V12's. I had a 3ltr X Type and I hated it. I loved the car but not the mechanical side of it. I got rid of it and bought a 2,1Ltr FWD only model as a compromise. It is simpler overall and as you know I can get the 3 rear plugs and coils out through the intake manifolds which I could not on the 3ltr model. However my 1996 x300 4ltr Straight 6 is much easier to work on than my X Types stupid V6. I would have preferred that they had used a simple 4 cylinder engine in the X Type. Now that would have been very smart and and more practical. But then the average motorist must have more money than senses, and so they are their own worst enemy.

    A transmission filter change can also turn into a much longer job when the previous well meaning person torques the pan bolts to OEM specifications, but the OEM specifications are for a perfectly clean, dry, tapped hole. Unfortunately, most people don't clean out transmission pan mounting holes with brake cleaner and compressed air before torquing the pan screws, so they almost always over torque them. A bent pan or stripped hole are the result. Fortunately, it's easy to fix, and the well meaning previous "mechanic" should be commended for caring enough to change the transmission filter. Over torquing is a very common issue with valve covers as well.

    The only reason I'd buy this year of a Jag is to get one with the straight six. When I was a kid we had a brand new '89 XJS with the V12; one that a local dealer gave to my family on a trade in '87 Sovereign that also junk from the factory (if I recall; there was a part in the motor that required a machine to remove of which there was only one in the country so it was not feasible to do within a reasonable time.. at least the dealer did something though.. imagine going through this today with a new car, you'd likely be stuck with it!). The XJS ended up with the fuel injector problems, naturally; as well as other issues over the years. As a new car the XJS broke down on a road trip and the motor had to be removed just to replace a power steering line!? At the same time back in the day we had an '87 Cadillac with the 4.1 which had less problems and was therefore more often used as a daily driver; now THAT is saying something!

      Remove the engine to replace a power steering hose? Your mechanic was playing you for a fool. It's an awkward job (done it on XJ12 and XJR-S) but the engine doesn't have to come out. While you've in there replace the rack bushings with polly items.

      @@albanana683 Just to document the story correctly for once and for all, I have actually asked my family member (now in their 80s trying to recall it) what happened after I read your comment. When this happened I was probably a toddler.
      As the car was being fueled in Eugene, Oregon it was realized the antifreeze was leaking out all over the place. The fellow working at the gas station suggested it be topped up with water and driven to the mechanic across the street.
      The mechanic across the street didn't want to touch it so called a tow truck to have it brought to the only dealership in town at the time which was a Subaru dealership.
      One of the fellows who was a mechanic there happened to work in the Jaguar factory years earlier in Coventry. He was able to take a Subaru hose off the shelf, cut the ends of it, and rig it into place in order to get the cooling system working again. However, somehow in this process the power steering line got cut and the car was soon without power steering for the rest of the trip. Upon returning through Eugene, the mechanic did not want to take responsibility for the problem.
      Once back in town from the trip, the car was brought to the dealership and fixed properly. As I recall the story as originally told to me, the motor was removed for this; though this part of the story wasn't exactly confirmed just now. The car was not likely under warranty at the time.

    Wizard , the reason for the plugs in the centre of the engine is because it is a "Heron" head engine, with the combustion chambers in the heads of the piston rather than the cylinder heads. To get effective combustion, the spark needs to be quite central in relation to the Heron recess in the piston.

    • @raynic1173

      @@raynic1173 There is nothing in my Jaguar history about redesigning the cylinder heads of the V12. Given that production of this engine, by the time the 6 litre came along, was only a few hundred units a year, I doubt that the expense of the extensive redesign to change from Heron combustion chambers, making new cylinder head casting patterns, new piston design and new longer con rods, would have been economical. The specific output of the V12 engine remained very modest at barely over 50 BHP/litre, when for example the contemporary BMW M series engines were approaching 100 BHP/litre.

    • @mark_p300
      @mark_p300 Рік тому +4

      @@wilsonlaidlaw Utter nonsense. First of all the Heron heads were done away with in 1980, with the switch to the "HE" design, so the idea that the spark plugs had to go there because of the dished pistons is moot: Jaguar V12s, both 5.3 and later 6.0 litre versions, didn't have Heron heads after 1980. (And the idea that they "wouldn't have gone to the expense" is silly to begin with; after all the 6.0 had a completely different crankshaft! Not to mention the entirely different electronics system (including the Nippondenso distributorless ignition system unique to the XJ12)...
      Secondly, the spark plug access location had nothing to do with the original Heron head design anyway: they were accessed from the middle of the vee-nearer the intake ports-simply because the intake manifolds were located on the outside of the vee, above the exhaust manifolds. This was done to keep the overall assembled height of the engine lower to fit under the very low hoods of the E-type, XJ and XJ-S! This significantly limits the efficiency of the engine's "breathing", which resulted in the ~50 hp/L output. (The contemporary BMW M70 V12 made ~60 hp/L.) If the spark plugs were located outside the vee (like in a Heron-headed Ford Essex V6 in a Capri, for instance) they'd have been completely inaccessible without taking the intake manifolds off!

    Around last year I purchased a 2000 Lexus RX300 SUV for my girlfriend for 2 grand, in coincidentally the same hunter green color as your new Jag. We got it at 219,000 miles BUT, I knew after looking it over quickly that it was not a rust filled piece of junk and it’s a Toyota so I trusted it to work as a daily driver. When we got it the only things it needed were new rear struts and new tires all around. Today it has just shy of 232,000 miles on it and the only thing really wrong with it is it will burn maybe a quart of oil every month or so, so I’ll top it off every month to keep it in check. That’s just from poor maintenance in its past but really with 232,000 miles on it it’s not a big deal. We’re just going to continue using it until it can’t run anymore. The proof is in the pudding guys. When the car wizard suggests buying a Toyota product for the best reliability, he means it. It’s not because he gets a cut from Toyota to promote their cars. Their cars are actually just that good. Not without fault because they will have problems, but compared to other makes they have proven to be the most reliable!

For example, the vehicle to buy in the used market is the second-generation, 2007 to 2012 Hyundai Santa Fe AWD or 4WD mid-size SUV with the 3.3 L or the 3.5 L V6 and the five-speed or the six-speed automatic transmission with manual-shift mode and the vehicle not to buy in the used market is the second-generation, 1998 to 2004 Isuzu Rodeo 4WD two or four-door mid-size SUV with the 3.2 L or the 3.5 L V6 engine and the regular four-speed automatic transmission. The Rodeo had a lot of problems and there was a recall, back in time after Isuzu was out of production almost twenty years ago. The Santa Fe is a better vehicle, because there is a lot of them currently on the roads within North America and their reliability for the older, second-generation is excellent. The newer ones are just problematic with technology and full of recalls, especially the Santa Fe Sport with the 2.4 L four-cylinder and the 2 L turbocharged four-cylinder. Finally, the Car Wizard will be surprised to do more of these videos for the continuation of the new year to come, before the next holiday season approaches following the American Thanksgiving. Thank you very much and have a great weekend.

I once picked up a van I used to own after a service, drove around the corner and lost power and a colossal misfire made itself known. I stopped and could see what the issue was when I did some basic checks. Both the oil and the coolant had turned into a milkshake. I continued around the block and back into the mechanics bay and said, "I think the head gasket has blown, is it OK to leave it here until you can find a spot to look at it and replace it and I'll get the train home?" They were dumbfounded that I wasn't screaming and ranting that they'd broken my car. It was just one of those things. We had a good chat about looking for other potential issues with the coolant system and engine block and at 3pm the next day they rang me to pick the car up and they charged me for the parts only, as it was such a simple job and I hadn't been a dick. I made sure that their Friday night beer fridge was in good order.
