I don't know if I should continue here or better open a new thread, but...
I live in Romania and I'm sure I have a vacuum leak. I have a 2000 S-Type 3.0 V6 so I decided to buy all gaskets/o-rings and also replace spark plugs & coils. I also need some other spare parts, but it seems the prices are higher than thouse you found, so I was wondering if anybody has already found the best dealer.
Here is a price offer:

2 x Manifold inlet gasket lower new 11,70 Euro each
2 x Manifold inlet gasket upper new 9,70 Euro each
2 x IMT O-Ring new 2,95 Euro each
1 x Fuelfilter new 14,- Euro

2 x 5R55N 4-3 Prestroke spring you canīt buy it separat, you have to buy the hole valve block.
1 x Oil kit Gearbox new 30,20 Euro

6 x Spark plug new 5,88 Euro each
6 x Ignition coil new 41,50 Euro each ( if you buy 6 of them )
1 x Oxygen sensor new 119,- Euro

All parts are original Jaguar parts.


Shipping to Bucharest will cost 35,- Euro by UPS.

Do you think I'll be able to find better prices?

Any suggestion is highly appreciated!

 

Manu,

I've moved you to your own thread.

The prices don't seem too shocking, but buying the whole valve block for a spring is a bit of a shocker.
This tranny is used in a number of Fords maybe you could try that route for spares?

 

Seems very reasonable. Probably could safe on the coils though.
you do not need the manifold gaskets. But do buy the elbows!
Are you doing the transmission youself?

 

Don't change the trans spring unless you know it's needed (it probably isn't).

Post more details of the car - mileage and what is it doing that it should not be doing?

 

Thanks everybody for the answers. Some prices seems OK to me, too (but consider it's Euro, not USD). Some other... pretty expensive (for example the ignition coils). But I guess I don't need Jaguar original spares, do you think quality parts could be found at other producers?

Some background of the car:
- bought first S-Type 3 years ago, ~120.000 KM
- changed all brake pads & discs + engine oil & all filters + spark plugs (I didn't saw the operation, but I'm sure the mechanic reused the intake manifold gaskets)
- after few month had trans problems: strange sound (like metal hrshhh)
- changed trans filter and trans oil (used Castrol Mercon V)
- soon the reverse didn't worked properly (worked after 30-40 seconds since I move the lever, only if I accelerated few times)
- after a 120 KM trip (sportive driven), I parked the car and the second day the trans seemd to be dead (no R, no D... nothing)
- after few winter months (the car just stayed parked) it started to work in D, and sometimes in R (with delay)
- requested price estimation to repair trans from more "specialists" in Bucharest and it was 1000 - 2500 Euro
- didn't use the car for a long while
- 1.5 years ago bought second S-Type (RWD) with 1000 Euro (just for spares) and replaced the trans as it was (no oill/filter changed)
- sometimes received "gearbox error" and noticed the loose of the 5th gear
- bougth ELM327 and read codes : P0734, P0735 (that's why I want to replace the 4-3 spring)
- 2011 february started the car (not used it during winter ) and the engine was shaking very strange on idle
- ELM327: P0303 Cylinder3 missfire
- changed spark plugs, changed coils (between them) few times but the missfire stayed on cylinder 3 (never replaced gaskets)
- noted oil inside manifold (but ignored)
- removed fuel injectors and took them to ultrasound cleaning (were also tested, 90-95% in parameters)
- after mounting everything back, the shaking was still in place but the error codes were different: P0171, P0174 and also some others related to O2 sensors (I have at home a file with all codes readed & deleted during time)
- recently removed the manifold more than 3 times trying to seal the possible vacuum leaks near both upper & lower intake gaskets with some red/black siliconic "thing" but the shaking was always in place at idle (also noticed that the fuel consumption is enormous, but the performance is very low: I was trying to move faster than a 520 BMW E34 and couldn't)
- when I removed the fuel injectors haven't noticed any elbow or air tube in that area. I also don't have the EGR valve on the top of the manifold (there is only a cap there). Do you think I simply didn't noticed the elbow, or it's possible not to have it?

Except the first change of filters/oil, I did the rest of the operations (helped by one or another friend), and I plan to do the same in the future since I don't trust any service/mechanic around. I've been through a lot of situations (which now would be just hilarious stories) so I learned that even if it's slower, it's safer (at least) to be there when the car is repaired (involving in the repair process is even better).

Now the car has ~150.000 KM (haven't used it too much), but I really want to fix it

I read a lot on this forum and I plan during weekend to confirm the vacuum leak by reading the fuel trims (didn't know this till I read here). If I'll find a good price & buy the parts, I would renew all 4 gaskets + the IMT o-rings. I'm still uncertain about the PCV valve's elbow since I didn't noticed it when everything was opened, but I'll surely look more carefully next time.

Any suggestion is precious

 

For the location and repair of elbow under lower intake:
Jaguar vacuum leak p0171 p0174 s-type 3.0

After jerking around with the upper and lower intakes, I would definetly replace the gaskets this time!

 

Thanks Rick for the link (already read it - actually this post was the one that bringed me to this forum while googleing).

I found few different part number for the gaskets:

Manifold intake gasket lower XR8539 / A8040-169254
Manifold intake gasket upper XR85294 / A8040-120837

And these not specified if are upper or lower:
FEL-PRO MS 96475 / IMC 223 26011 001 # 223 26011 001

The X... seems to be more expensive than the A8.... - anybody knows if they are the same ? (A8... appeers to be for the 2004 3.0 - are they different?)

Thanks!

 

Bad fuel consumption is often due to misfires. The lean codes say so, too. There's an OBD test (quiz) in another part of the site about it but the basic is that the car has no fuel sensor in the exhaust so cannot tell there's extra fuel. It does have O2 sensors so can see O2. A misfire is extra fuel & extra O2 but as I just pointed out only the O2 is seen. It looks like an air leak (or bad MAF) so the PCM adds more fuel to "correct" it. Wow - even more fuel!!

Worse.... it then burns in the exhaust/cats and damages the cats

You probably have a bad coil on #3 and quite likely a bad PCV elbow as well. I don't know about the "missing" EGR as the 3.0 isn't my thing.

As the coils are expensive I'd buy at least 2 (1 you seem likely to need + hopefully a spare) but maybe not 6. (They're not very expensive for the early 3.0 in the USA but where you live? Ouch? Maybe you can find them at - say - a Ford garage? If someone has Ford part # / WERS # for them.)

 

MY's 1999 through 2002 lower intake gaskets are much different than the MY 2003 and up.

**See post #12, this thread. Page 2 on attachment.**

 

Thanks guys for replies.

I thought the same, but I replaced coils between them and the missfire remained always on the 3rd cilynder so I presume it was the fuel injector

In the pictures from here Jaguar vacuum leak p0171 p0174 s-type 3.0 you might see the EGR valve, but look here: http://goo.gl/39qdp (there is only a metal cap instead of the EGR valve). Mine is the same (without EGR), so I was wondering if the faulty elbow exists (since the vacuum pipes should be different)


How true! I found these SMP# FD496T in USA with €16.99 each (€138.06 6 pieces + shipping). In RO, this is the price for 2 pcs.

Below there are some refs of coils menioned as suitable replacement for the OEM Ref # CS2 42571 / CS2 42571 E :

STANDARD MOTOR PRODUCTS # FD496 / FD496T
MOTORCRAFT # DG528 / DG517
FORD # 2W4Z-12029-AB / 2W4Z12029AB / 2W4E-12366-AC / 2W4E12366AC / 2W4E-12A366-AC
AIRTEX # 5C1179
AC DELCO # F569 / F-596UNITED IGNITION WIRE # COP12

Do you know if the Lincoln LS intake manifold gaskets are suitable for S-Type?

Since the discussion slides in this direction (OEM parts replacements) I'll share some of what I found so far:
Manifold intake gasket lower XR8539 / FEL-PRO # MS 96475 / VICTOR REINZ # MS19607
Manifold intake gasket upper XR85294 / FEL-PRO # MS 96484

Fuel filter XR81775 ( MANN WK512) F65277 F65277 GF65277 33595 33595MP G8018 G6593

Do you also have other? Maybe they're usable for somebody in the future...

 

this is interesting:

 

Page 2 on this thread shows the difference between MY's 1999-2002 and MYs 2003-2008 lower intake gaskets: https://www.jaguarforums.com/forum/s...d-57039/page2/

Yes the Lincoln gaskets fit Jaguars and vise versa if one wishes!

 

I suppose the EGR may not be required by the local laws and then there would have to be unique software inside the PCM (else it would throw EGR codes).

PCV is separate from EGR but I suppose something equivalent could apply.

I don't know what that blanked off part is - EGR? PCV hose end?

If the misfire stays on #3 usually either you misunderstood where #3 is (pictures in elec guide & in Vehicle Specs - be sure to use the corect pic for your car era) or if you have the right cyl then having tested the injector that leaves: bad wiring/connector, compression, PCM. Or maybe something else I've overlooked - what?

 

Thanks, Rick!
Do you also know if the IMT Valves' O-Rings are the same? I noticed that IMT Valves are mounted in a different place at the newer S-Type, have they also a different size?

I'll try to make some pictures next time I'll take off the manifold, probably that would clarify our questions and also help other people in the future

I'll "confess" that I was not sure which is the 3rd so I disconnected the coils wires to cause missfire codes on OBD in order to clarify this After being sure which is #3, I switched the spark plugs & ignition coils, but missfires remained on #3. Then I hoped there is a wiring problem, but is was not. Then I measured compression and it was exactly the same for all cilynders (can't remember now the value). Finally I presumed that the #3 fuel injector, instead of "spraying" the fuel, was just dropping it so the #3 spark plug became too wet and didn't fired; the lean code added more fuel and so on.... Unfortunately the mechanic who cleaned the fuel injectors tested them only after the cleaning, not before (so I could never know if my presumption is right). What's certain is that after mounting back the cleaned fuel injectors, the missfire code dissapeared (but the others corresponding to vacuum leak appeared).

I don't think I'll have the parts in time in order to replace them this weekend (since I didn't even ordered them yet), but at least I'll test the fuel trims and took a closer look searching for the elbow connector.

 

Sounds like progress so far

You'll have noticed Rick knows far more about the 3.0 than I do.

Sometimes lean codes on both banks means a MAF problem so have you tried cleaning it with MAF cleaner? (carefully) Oh - but did you disconnect the battery after the fix? That clears the KAM (keep alive memory) to remove the bad learned data.

 

If your asking if the LS utilizes IMT O-rings, NO! They do not have the tuning valves.

All MYs use the same size O-rings.

 

Funny I was thinking the samething. Beaware sometimes cleaning just doesn't do the trick, replacemnet would be necessary.

 

Here's the file to confirm the cylinder numbering if you need it again.

Sounds like you are getting the better of the problem.

 

The fix was actually done in steps during few month (since the isuue started in February)... I disconnected the battery only few times, not after every step...


I cleaned it few times with electronic pieces cleaner (spray) but there was no improvement. I'll try to take the MAF from the other car and try, maybe it will work - thanks for the hint!

 

After few month of not using the Jag, I decided it's time to take care of it and to try to fix the engine problem. So I stat by replacing the MAF and measuring the fuel trims. Changing the MAF (then disconnecting the battery) did not significantly affected the measured values... it seems there is a major air leak on the Bank1. Below there are the results just after a battery disconnection.



So I guess I have to check the upper and lower gaskets on bank1 side (that's the one with cylinders no. 1, 2 and 3 - right?), and the o-ring that seals the intake manifold vale corresponding to bank1.... Back to work now, I'll let you know the result (hope that would happen sooner that the last time)
