2005 XJ intake manifold removal
Good afternoon
If anybody has a step by step of photo's of the intake removal please post, also any torque pattern and spec's, I'm replacing the thermo housing & stat, valley hoses, serp. belt and tensioner/pulley....maybe the water pump as well.....while I'm there.....any thoughts on a non OEM water pump?
Just wanted to know if there are any landmines along the way? I'm good up to the intake at the TB flange, a quick look...... 10MM bolts for the intake?, layback the wiring and rails? Can't see what might be lurking under the cowl rear of intake? Any help would be great!
Cheers !

Here are some threads that discuss their experience with removing the intake manifold.

Thank you all for your response! You guys have been a great help.
The hose under the intake was not leaking, seams like the plastic piece that is flanged to the engine, part of the T-stat housing was the problem. Looks like a porosity issue throughout the fitting. I assume the plastic is just breaking down. I did a bit of digging and thanks to NDW ....found the torque sequence and spec for the intake.
I plan to definitely replace the belt, pulley and tensioner. there was a bit of a squeal when I took it out of service.
Car has 124,000 miles.
If time allows I'll tackle the sensors and ejectors. My wife wants her "Baby" back! I mean her Jag back! Ha!
Any TB cleaning suggestions?
I know this is a non sequitur to this post but has anyone found out what causes the front suspension to drop only when its extremely cold? below 25F for days? When it gets warmer..problem goes away? any thoughts?

One or both of the air suspension shocks in the front have developed a leak. TONS of threads about this. Very common problem.

Back to your main topic, you can download the Jaguar X350 Workshop Manual in six sections at these links:
Table Of Contents
General Information
Chassis
Powertrain
Electrical
Body
Regarding the water pump, you do want one with a plastic impeller and not one of metal because of the OAT coolant used. The replacement pump Jaguar is currently supplying appears identical to the Airtex AW4124 available very inexpensively from Rock Auto (Airtex is an OEM to Ford and others). The pump comes with a paper gasket instead of the OE metal/rubber design. I've installed several of these pumps in X100s, X308s and X350s with the paper gasket and have had no leaks, but if you'd rather use the OE-style gasket, Rock Auto carries one by Mahle (part number K31850).
Cheers,

Hey guys! Don't mean to hijack your thread but I'm actually in the process of removing my intake manifold to get at my knock sensors and I'm having a hell of a time. I've got all 10 bolts out of the manifold, throttle body removed, left and right side wire harness mounts removed, fuel line disconnected, injector wires unplugged, the two bolts holding the rear wire harness. She just don't won't budge. Temps are between 40°F/4°C and 53°F/12°C where I'm working and I've even tried it in 80°F/27°C weather to no avail. Any help would be greatly appreciated!

We'll be happy to try to help but without knowing the year, model and engine of your Jaguar we can only guess at how to give you an accurate reply.
It's a good idea to use your User Control Panel (User CP link above) to add this information to your signature line so it shows up with every post you make.
Cheers,
Don

My apologies Don! I feel like I've typed it out in almost every other post I've made, hence I just assumed others would remember what it is we all own (we're a family here!) But I will correct this forthwith! To the point: she's a 2007 XJ8 NA with just shy of 189,000km (117,000mi) I may have forgotten a few things I've disconnected (EGR amongst them) unfortunately I also managed to break one of the tiny vacuum hoses in two places when just getting started but I'll figure out a way to MacGyver it back together.
Here's a visual aid!
EDIT: Signature was there but hasn't been showing up on posts? Would it have something to do with me using my phone to post? Also it's nearly midnight here and my garage lights kinda suck, sorry if the photo is crappy

Yes, it probably is due to using your phone. It may work if you use the "View Full Site" option on your phone, but it may be more cumbersome to navigate the forum that way.
My guess is that if you have removed all the fasteners, your fuel injector O-rings are sticking and making it hard to pull the manifold off, in which case it may help to pull the injectors out now. Check the photos in this eBay listing to see what you're trying to remove:

The Workshop Manual procedure is a bit sketchy, but it would be worth confirming you have disconnected everything you are supposed to. You can download the manual in six sections at the links below (the intake manifold removal procedure is in the Powertrain section):

Never thought about that. I saw so many people saying they simply left the injectors in the housing and it was no big deal, as for the workshop manual I've had it on my phone for a while but it's not the most descriptive thing out there, though it has helped me in the past with other repairs. Thank you for your help Don! Hopefully today is the last day I have to bug people about this silly manifold!

So.. do I just Pull on them to remove? Probably a stupid question but I'm very wary of breaking more parts as I'm not exactly in a position to be buying new injectors right now. O rings I can replace if need be. I'm still learning more about working on cars, so I apologize if any of this sounds dumb

Removing the injectors should be a matter of twisting clockwise/counterclockwise along the axis of the injector (not sideward) to help break the O-ring seal, and simultaneously pulling upward. Here's what the injectors look like (courtesy of our sponsor SNG Barrett):

Seems to me that if you have removed all the fasteners it is only held on by the seals
as Don has said.
I think you need to split it with careful use of a wide blade (maybe old chisel) along the edges.
You can see where the seals are located here to avoid those areas.

I was reading a couple of the TSBs regarding pinging and they only mention a software update? I had the car in to see several mechanics regarding this issue and they've all either failed to hear it or said just don't worry about it. The problem is I was never able to demonstrate the noise properly, but if I do a brake stand it can be heard. From what my friend (who is the only one who has heard it properly) tells me it's quite violent.
