Default Intake Manifold Bolt/Stud removal

Hello my name is Brandon and I am the proud owner of the 2005 Jaguar X-Type Platinum edition. I just recently purchased the car from my boss and really didn't want to sell it but he needed to at the time and the car has been sitting for 6 years. I got a hold of it and washed it up got it cleaned up and actually got the thing running after 6 years. I heard that it was having transmission issues so I changed out the transmission fluid and change the fuel filter and now I'm working on the plugs and coil packs but I have ran into an issue. Upon removing the intake manifold bolts all the two came out. And one of them came out completely with the bottom stud attached to it. Now I've been reading some forums on how to extract the intake manifold bolts if they are stuck but I've also read where two of them are supposed to remain spending and you have to pry up on the intake manifold to get it loose to get to the spark plugs. How much of this is true because if I have to pry up on my intake manifold then I'm going to need to find a way to extract those other two screws that are not coming out. Any type of help would make my day. Thank you I can't wait to drive this cat on the road

MoriarityOne, I think you are misreading what is meant by the 2 bolts needing to be still installed to remove the intake. There are 2 bolts that are notorious for sticking and having the metal part of the lower intake come free. So, what we have figured out is you remove the bolts that you can and then you use a large screw driver or something similar and pry up on the intake as you try to remove the bolt. This will pull the metal insert out with the intake. From there, you can remove the metal insert and then glue it back into the lower intake. Since you are in there and based on the age of the car, I would recommend replacing the upper and lower intake o-rings. Going to run you $40 or so, but it will save you from having to rip apart the intake in a year or so. Of interest, the upper intake o-rings you can get at any auto parts place telling them that you have a Jag. For the lower, you can try telling them that you have a Jag, but odds are, they are going to tell you they don't have them. But, if you tell them that you need the lower intake o-rings for a 05 Lincoln LS 3.0L engine, they will have them on the shelf. Same o-rings.

Read up a lot here. You will find that if you are going to have an issue with this car, odds are it is going to be a vacuum leak (hence why I say to replace the intake o-rings). We also have what we call "the big 3". IT is 3 parts in the car that are the notorious leakers. Probably a good idea to atleast look these over with a fine tooth comb and make sure that they are good. If in doubt, replace as these parts are cheap and will save a lot of cussing later on.

Ill add to Thermo to add a drop or two of lube to each bolt threads so the bolts will not stick in the BRASS inserts. Also use a plastic epoxy on the inserts to reseat.

Brandon welcome to the community.
I just went through this process while chasing down some misfires with my xtype.(See Misfire Mystery) I had all but 1 bolt out while attempting to remove the intake. It was the one on the far right (drivers side) Not the back one but the front one. It just spun in place, telling me the captured brass nut had broken loose. I tried the large screw driver pry method but to no avail. In my case I was able to get another set of hands on it and pried from the left side and the right putting pressure on the rear of the manifold. I was a little hesitant to do this but it was my last resort. With pressure it suddenly popped up releasing the bolt. This fix was to JB weld the brass nut back in the hole being careful to get the placement correct. It stayed and I was able to finish replacing all plugs, coil packs, upper and lower gaskets and a bad injector. When I reassembled I made a note to not over tighten that bolt. If you need advice on what parts work best please just ask.
Good luck. Hope you have success soon.
