Next things to work on are some cosmetics inside and out as well as the HVAC system.

I've now owned the car 3 years. And since the tires have been sketchy and old since I bought them, I decided to buy new tires. In Seth's words if something goes wrong because of old tires "it's starting to be your fault". Yes, true.

I did pick the right day to make the slightly more than an hour drive to tire rack:

With the new tires, I was no longer scared of taking the jag on road trips, and I drove the jag about 7 hours total this weekend, much of that at 75ish on the highway. It's not fast, and not great aerodynamically, but otherwise it's a great highway cruiser. 

Some items I do want to work on fixing, in no particular order:

  • HVAC needs work. Heat was intermittent, ac doesn't work. 
  • There is a rattle in the rear parcel shelf. I think it is an air damper that is missing a spring or something.
  • Both side marker lights on the passenger side are intermittent. Very odd, but should be fixed.
  • No cruise control. This and HVAC are heavily reliant on vacuum lines, so I have suspicions. 
  • Wipers don't park. Have to try and turn them off at the perfect instant.

This thread is giving me all kinds of motivation to work on my '84 XJ6. I love the color on yours, definitely stunning. 

For the rattle in the rear parcel shelf - might be the air vents?

Yes I think it's exactly that. The "cow bells". 

Though I do not find the constant rattle to be endearing like some of the jaguar owners in that thread!

This car is one of those classic cars that looks really good at 50' away and then looks even better 5' away when you realize it's nearly perfect.

Well, I forgot to mention that tire rack found a loose hubcap due to a broken tang ok the clip. Today I fixed the clip, and reapplied the hubcap. Nice.

I think I may have fixed the heat at least for now, and the rest of the HVAC seems to be operating correctly sans refrigerant charge.

Here is the old heater valve and the box of the more recent until I replaced it with. The valve actually seems to be working now that I removed it from the car, but maybe it was jamming up?

I snagged the bracket from it to use to support the new valve. (This new part number is not jaguar, but functionally it is exactly the same and supposedly much more reliable than the jag pieces).

Fixed 2 small things tonight. Very small things maybe, but still feeling pretty good!

#1 - the speedometer also had the odometer and the trip meter. The reset button on the trip meter was not working, and the trip meter was like in between digits and not rolling over appropriately (when the tens would go from one number to the next, the hundreds digit would also often roll).

So I pulled it apart. It actually comes out of the dash super easily, push in and twist counter clockwise and it pops out. I fully expected to find some broken plastic inside, but instead all I found was that it needed some lube. 

The reset mechanism threw me for a loop for a while, because I couldn't understand how it worked. Finally I figured I'd just apply more lube to see if that helped (never hurts, right?) And it did. Then I realized how the mechanism works. There is a cam on the side of each number wheel, with the high point at 0 and the low at 5. When you push the reset, the button pushes a flat bar against the cam and the cam is supposed to drive the number wheel around. So this is like the tappet driving the cam instead of the other way around! You can see how it would be very sensitive to the least bit of resistance.

Anyway, went for a short drive and the reset works beautifully now, and the numbers all appear correctly in the window instead of half and half. We will see if there is an improvement on rolling the next number wheel correctly but I think there will be.

#2 - one of the two rear license plate lights was out, causing a light on the dash (bulb out warning light). I pulled out the bad bulb and searched online for a new one. Cross references to mgb stuff. Mgb! Duh! I have a ton of mgb stuff. Looked through a big spares box I got last year and voila, there's a bulb that fits. Nice! No more dash light, all my lights appear to be functional now.

And another fix that just required a bit of additional lube - the cruise control!

This bellows is just a "press fit" on the plate that pulls the cable as well as the plate on the rear. Apparently this is a common place for vacuum to leak out. Common solution is to apply a silicone type product to make a more permanent seal. 

I wasn't quite ready to try that but I did want to test the theory. So I used some grease around the inside lips of the bellows figuring it would help get an airtight seal.

After a short test drive, it seems to have worked beautifully! I am a little worried that the grease may not hold up long term in the high heat environment right over the exhaust (I could see it seeping down to the bottom when hot and leaving the top dry), but we will see.

I'm so proud of how well you are taking care of your Jaguar.   Bit  by bit you are solving issues that have condemned many of them to the junkyard. Doing so at a modest cost and without endless hand wringing about poor engineering and lousy quality.  
I'm pretty sure you could reap a nice finical reward if you were to sell it now, but recognize it's still worth more than even that.  
Well Done

I was just thinking about how sometimes it is really rewarding to work on these small jobs. Driving the car is a joy, and fixing little things is too.

Now I just need to get the dang AC working.

Here's where I'm going to suggest a departure.  Toss out that A/C compressor and buy a newer style. GM,  Sanyo or something.  ( Rock auto is your friend)  Before you recharge it do a leak test on the rest of the system.
      If it needs work there are 2 bolts in the engine compartment that need to come out.  Then with a little exploring under the dash you can pull the rest of the system out.
