I struggled and struggled and eventually got between 4 and 5 ounces out, but it took about 6.5 ounces to fill it up. I may have gotten more out than I thought though, I spilled a little here and there.

With regard to the plugs, the previous owner drove the car for 10 years and had the 90,000 miles service done at Guadin Jaguar in Las Vegas. Either the NKG 7866 plugs were original from the factory, or they were installed by Guadin Jaguar at the 90,000 mile service. Either way I feel comfortable sticking with the same plugs. Well, as comfortable as anyone can be after reading a dozen threads on spark plugs, haha.

 

The obstruction for the straw is the gear itself. There is no getting around it.
As you found, just angle the straw and let it bend a bit.

I posted a link to a PDF version of the service manual at a dropbox.com address,
and another member posted another link to one at dropbox as well.

They are complete, and far easier to use than the browser version. Just print out
the few pages you might need for a job and highlight the torque values before
going out.

As for plugs, most of the debate centers around those who will not actually
read application catalogs. Nor would they even understand them anyways.
I go for the base fitment parameters, then play around with other characteristics.
Trying the new Denso needle electrode plats next.

 

I drove it to work today!

The speaker pop when the ignition is turned on and off is still there; the new battery didn't solve that. Also, when the ignition is turned on but the engine is not started, the alternator whines/hums. I replace the ground cable from engine to frame, but that is the only ground I addressed.

Drove smooth and fast; not as smooth a ride as my XJ8, but still a nice ride.

 

Alternator issue?
Have you checked voltage output?

 

According to the Ultragauge it is steady at 14 volts when the engine is running.

 

I want to thank you all for your contributions. Here's what I have accomplished this week despite a heavy work schedule.

1) New rotors and pads all around/ flushed lines with new fluid.
2) New valve cover gasket set, both sides.
3) Replaced differential fluid and cleaned breather.
4) Changed fuel filter and air filter.
5) Changed oil/filter, dropped pan for cleaning and installed new gasket and drain plug.
6) Dropped transmission pan, thoroughly cleaned then installed new filter and gasket, topped off with new fluid. It only took a little over 3 liters so I will pull out and replace 3 liters at a time every couple of weeks until I run out of fluid (about 3 more times).
7) Replaced accessory belt and supercharger belt.
8) Replaced supercharger oil.
9) Pulled out 1 quart of power steering fluid and replace with Lucas power steering fluid conditioner.
10) Replaced engine to frame ground cable.
11) Replaced broken signal light lens.
12) Installed new spark plugs.
13) Tightened throttle cable/cleaned throttle body and MAF.
14) Rotated tires.
15) Used grease gun to lubricate where there are grease fittings.
16) Replaced lower front shock bushings.
17) New battery
(Bought a new water pump, thermostat, coolant temp sensor and coolant but decided to wait and perform that at a later time)

The few items left on the to-do list are:
1) figure out why there is an electrical "pop" in speakers when ignition is turned on and off.
2) Conduct smoke test as fuel trims still show a vacuum leak (doing this tomorrow morning before work.)
3) Find and replaces missing sunroof trim piece.
4) Adjust/replace driver door handle cable.
5) Wash and POLISH the car and clean wheels. It desperately needs a coat of wax/polish.
6) Learn about the shifter sensor (p0705 came up but went away, expect it may come back)

I am probably forgetting items on both lists.

I drove it to work for the first time today, what a kick! It's amazing how much faster this car is than my XJ8. The ride is less smooth, but still very comfortable. In a word, it's "fun".

 

Wow, you got to work on that car quick!

Whenever I drive my XJR it just puts a smile on my face, as it propels you forward so effortlessly and quickly!

Your alternator is not humming when your ignition is turned on, that is the aux coolant pump. It is an inline electrical pump that circulates the coolant from the charge tanks on each side of the SC to the intercooler in front of the car. It runs when the motor is running or the ignition is turned on. It is essentially a separate coolant circuit from the main cooling system, but they join together on a couple hoses for expansion, ect.

 

The vacuum leak is most likely from the brake servo/booster line where it joins into the 90 degree elbow below the throttle body.


The rubber O ring in the quick connector fails, You need part number C2S15816, I believe it is for a V6 X type ( it is the same fitting as on an X308, but you have to buy the whole elbow for a X308 ) fit the new black plastic fitting onto the pipe, remove the O ring from the brass fitting and fit into your existing brass fitting, plug the hose back in.


The fitting was less than £10 from my local Jaguar dealer, so about $15-$20.

 

Good call on that one..

 

Look what I just happen to have in my toolbox still in the original bag. I ordered it a while ago for one of the other cars and ended up not needing it. I think I will replace that fitting, as you suggested Andrew, before I even run the smoke test.

So is the installation as easy as it sounds? I simply pull the old line out, replace the plastic fitting and O-ring and push it back in? Is there much risk of anything breaking in the process?

Thanks so much all of you. I would hate to have to own a Jag without this forum, much less 3 of them!

Ok, I see why it is not simple. Is there any way to do this without taking the throttle body off the car?

 

I can't believe I am going to ask such a basic question, but a search this morning before I left for work was a bit confusing.

What is the correct part number, or link, for the throttle body gasket -- 2003 XJR?

 

I removed the vacuum pipe from the servo/booster then removed it from the quick connector, I did not remove the throttle body, just the false bulkhead top centre section and the section over the servo/booster.


Sorry was not intending to mislead, but my XJR is Right Hand Drive so the servo is on the right, and so it is a straight shot to the pipe quick connect, I believe that the Left Hand Drive vehicles have the header tank and servo transposed, so it may not be as easy.

 

I find same throttle body for 2000-2003, but gasket is listed as-
NNE3021AC - THROTTLE BODY GASKET
FITS: 1999-2003 XK8 XKR FROM VIN 031303 TO VIN A30644, 1999-2003 XJ8 FROM VIN 853936, 2000-2002 XJR.

 

I finally got around to performing the smoke test, and amazingly that brake booster connection is not leaking. The EGR valve connection is leaking. I am having a hard time figuring out exactly what needs replacing, but there is a connection going from the EGR valve towards the engine, it looks like metal to metal with a gap and smoke pouring out. There is what appears to be an untightened bolt there, but I was afraid it was an adjustment bolt of some sort so I didn't mess with it.

I tried to take a picture of the inspection camera screen but it just didn't work.

 

Attached are pictures of the bolt that looks precariously loose, and the exact location of the vacuum leak (which is directly behind the bolt).

I have yet to find a way to get a wrench on that bolt, even if I was planning to try tightening it. I guess I should order all new EGR gaskets and a Throttle body gasket and then take it all apart to clean and re-assemble.

I will start searching.

 

Adding to my list of questions:

The upper shock mount unit (MNC2169AF) is not technically the correct part for my XJR with adaptive control. I have heard rumor that by using the existing bolt sleeve in the new mount, the part will fit just fine. Before I order the mounts I was hoping someone could confirm that.

Thanks

 

you looking at aftermarket or oem?
Just wondering because the (MNC2169AF)left, (MNC2168AF) right sells for $306.74 each
Were the correct for with CATS (MNC2169BE)left, (MNC2168BE)right sells for $100.67 each
Just what I find listed and wondering why you wouldn't just get the right ones..

 

One of the other members on here recommended the ones at Rockauto for $39 each; said they worked great on his XJ8. Those are the ones I was considering. They don't offer one for CATS.

I originally found the correct part numbers on Jaguarclassicparts.com and searched for them online, but found none as cheap as $100.67, which is why I was considering modifying the $39 parts. Where did you find them?

What I would really prefer to do is find the original orange spongy bushings and press them into my existing mounts myself. I have searched and searched online but can only find the urethane bushings available. I put those on my XJ8 and they are fine, but I would prefer to put the original material on the XJR. I could swear I saw them available somewhere when I bought the others last Summer.

I just placed the order for the shock mounts you referenced, thanks.

Incidentally, I discovered that the electrical "pop" at ignition on/off is the subwoofer in the rear deck. When I investigated it appears one of the amplifier connection points broke and fell into contact with the body of the speaker itself. The subwoofer was also making NO sound. I used a small piece of rubber heater hose to hold the connector away from the speaker and the speaker now makes a very small amount of noise and the "pop" is gone. I ordered a Speakerworks 6x9 speaker repair kit and when I remove the speaker I will try to repair the connection point.
