2003 3.0 - Intake Manifold coming off for plugs / IMT O-ring - what else should I do.

![Default](/forum/images/icons/icon1.gif)
Ok, so I'm going to have the intake manifold off to do the plugs as I approach 100k. (car has 97k).
Besides the OBVIOUS IMT O-rings. And the plugs, what else should I do / replace?
Mitchell Estimator Claims 2.6 hrs for Spark Plug R&R, including removing the Intake Mani. My very good friend is the mechanic and will charge me $100 for the labor, plus actual cost on parts (although he doesn't get much if any of a hookup on Jag parts).
What else should I do? I will be over his shoulder while he does this as well.

Thats 12 gaskets for the manifold, the lower ones aure in the fuel injection manifold and are alot more prone to leaking with age than the upper. Also that little "turrent" on top of the upper radiator hose matrix is very prone to breaking when you touch it. If it even looks old and stained from coolant. Buy that to have on hand and if you dont break it, return it. Or replace it as "preventative maintenance" it was engineered to fail by whatever company made it for jaguar

My car is a facelifted 2003 3.0 post VIN M45254.. (which appears to be the switch).
Here's what I've come up with so far:
Lower intake manifold gasket - XR843533 x 6 ~ $15 each
Upper intake manifold gasket - XR843536 x 6 ~ $14 each
IMT O-Ring Vaccum Seal Gaskets - C2S40669 x 2 ~ $3 each
Complete Upper Radiator hose matrix for 3.0 S-type VIN M45255 THRU N52047- XR854920 ~ $200.
Brutal is this part available seperately? The turret piece that you speak of that is so prone to failure? Any chance of helping track down a part number?
This is just online pricing from a website that seems to have a decent parts catalog.
I'm really tempted to replace all 3 ignition coils on that side as well, seeing as mine have ~ 100k miles. Would there be any issue with replacing just the 3 on the side that is inaccessible without the intake manifold off? This would pretty much ensure that the manifold wouldn't have to come off again for a while right?
C2S42673 for the coils - ~ 55 each.
And finally Spark plugs - C2S46895 x 6. ~ 8.50 each
This intake manifold design that requires removal to get to the plugs on the one side of the motor really does lead to excessive cost to do something as simple as a spark plug replacement - albeit that they are at 100k intervals.
I know I can prob find a better deal somewhere, and I will shop around but so far:
6 lower and 6 upper intake manifold gaskets = 174.00
IMT O-Rings = 6.00
Ignition coils (3) = 155.00
Spark Plugs (6) = 51.00
Total = 386.00 in parts. + 100 in labor. = 486.00.
Now that's assuming I don't need any coolant parts or coolant etc.

Now as far as Vin breakdowns:
The actual "face lift" and interior and engine changes happened in Mid 2002 - these cars are officially reffered to by Jaguar as MY 2002.5 + In the US, I think all the face lifted cars were sold as 2003 model year cars. Europe tends to list cars by month and year of production rather than "model year"
S-TYPE 2.5 V6 2002 FROM VIN M45255 ON
S-TYPE 3.0 V6 2002 ON FROM VIN M45255 TO N54027
The change to the N vin Happened in 2005 with the new front end, as well as the rear tail light / trunk changes. Apparently there are some changes under the hood at least to the cooling system as well.

George,
What actual spark plug does that Jaguar part number for spark plugs translate to? The factory plugs for a great many of these 3.0 S-Types (including our 2005 model) were Motorcraft, including the iridium ones that our car has. Given the modified Ford Duratech engine we have, that's understandable but not ideal.
My research indicates that the the best spark plug application for our 3.0 engines is the NGK TR6AP13E iridium plug. I've talked with several different Jaguar service departments and techs as well as techs in the spark plug industry. Hands down, the recommendation for both long plug life and optimum, consistent performance is the NGK plug listed above....

I'd be lying to you if I told you I knew. It was just the OEM Part # listed on the site for the OEM plugs. The 3.0 is BASICALLY a slightly modified and tuned Ford Duratec 3.0.
I am not in the least bit surprised that it came OEM spec'd with Motorcraft plugs. I will def track down a set of the NGK Plugs - thanks for that tip.
Now you've got me thinking... Trying to source the intake gasket parts and stuff from a Ford / Lincoln source rather than Jag parts. (at possibly a lower cost) The 03+ LS 3.0 is exactly the same as the S-types (including the intake mani - which I believe is unique to the LS / S). But mating surfaces should be the same... I used a Lincoln LS wheel stud set on my car, that was side by side the same as the mangled one (and the other 4 good ones) that came off my S-type, after NO one claimed to stock them for the S.
More research to come as far as possible cross references.

Ok Did some research here on the LS's 3.0.
Depending on the parts vendor they claim that these gaskets will ALSO fit the Jag 3.0.
For the 03+ Lincoln LS, the intake manifold gaskets are sold as sets of 6, made by fel-pro.
For the upper gaskets (refered to as plenum gaskets) the part # for the set is MS96496.
For the lower gaskets it is MS96485.
Both sets combined are around $75 for the fel-pro ford versions.
I got pictures of them relative to the Jaguar Gaskets, and You know they tend to look an awful lot alike to me.. They are definitely worth a try.. I don't know if Brutal or anyone else can shed more knowledge here. And I'm not trying to undermine the sellers of Jag parts either. But if I can get functionally identical parts by taking advantage of the former ford / jaguar corporate relationship. for 40% of the price of the Jaguar Version, I'm all for it.
Here's the pics. The fel - pro ones show you a pattern moreso, the jag pics are detailed.

We should have a Sticky of confirmed Ford / Jag cross referenced parts..
This only took about 20 mins to find, but I'm sure that it would save a few people $$.
Now, if we did a half decent search whenever there is a common replacement part. I'm sure it would be worthwhile, plus greatly increase parts availability because they could be more likely found at local parts stores / Ford Dealers.
I always tend to do cross references because half the reason I like these modern V6 cars is the fact that the engines are Ford Derived, and except for a few jag specific parts, most maintenance stuff can be found locally.
I'm not a moderator, but it's just a thought.
