Plugs need changing. Some coils may well also need changing. Oil in the plug wells needs curing. Otherwise, all may be well LOL

Hmm. Yeah I bet it may be time for a changing..I've read that some kind of foam can be sprayed into the oil wells to kind of clean and seal any possible leaks? I forgot the name of it..but it burns off and cleans the wells/intake..

I haven't changed my coils as of yet..would changing just one or two be suitable?

I would doubt it would be your alternator causing the flickering. Probably more that the car all but dies momentarily when the revs are bouncing around at idle. Fix the other things like the last poster suggested and you probably will be back in business.

Hold on the coils till you've done the plugs. The hard evidence still suggests damaged plugs.

You really should remove the cam box covers and fit new gaskets and do a proper job. That's my opinion anyway!

So when you say cam box are you talking about the intake manifold or where is the camera box that? I've replaced the intake manifold gasket before is that the same thing?

Not can you send me something I had a do it I know how to take out the spark plugs I know how to remove the intake manifolds what other steps to take to get the correct gaskets installed?

Any recommended spark plugs that I should get I called the Jaguar dealer and they are stating about eight dollars apiece and they are
pre-gapped.

Not a camera box but the cover over the cams as shown in the attachment. Nos 2 & 3 are the gaskets you need. The part numbers (and discussion on a very similar problem) can be found in this thread:https://www.jaguarforums.com/forum/x...eplaced-73685/.

ugh is it hard to replace those? I know I can get the top half of the intake off in a few minutes... but havn't gone beyond that.. what should I expect after trying to remove the bottom half of the intake to get to the valve cover gaskets? Should I try to replace spark plugs/intake gasket before I do valve cover gasket? Would it be fine to replace the 3 front spark plugs? Or should I just do them all..

and I heard Bosch double platinum plugs are good plugs to get, anyone know of a significant difference with bosch double platinum +4? vs double platinum?

Those plugs should be fine. They should be good for 100,000 miles. You can try changing only the front three and see if there is any improvement. The back three require removing the intake manifold as do the upper and lower intake gaskets. While that is off is the time to tackle the valve cover gaskets. I've not been able to find any instructions on changing the valve cover gaskets. There are probably other items that must be removed. I don't know where you're located but it's cold here and if you can wait for warmer weather it might make things easier. Good luck - I hope you don't get over your head here.

Ok thank you I think I'll try the plugs and hope that helps.

I think I'll change all..and maybe intake gasket.
Tackle the valve gasket later ..

If you take a look at the front cam box cover, you'll see that it will come off without touching the inlet manifold. The air filter box has to come out as do a number of pipe clips etc, but there's not much to the job. The rear cover is a different story; the manifold will have to come off for that to give access!
