Winter hack fail or genius? Broken Jaguar content

I managed to crack on with the engine work today, with mixed results 
Goodies ready to get fitted to the car. I replaced the fuel filter, engine oil and filter, air filter, spark plugs and coils on cylinders 1 and 6 (which were the ones detecting misfire on the fault code reader)
The old spark plugs. Look like they could have been fitted since new! Top left is cylinder 1 which was very badly fouled up.
Fanimold up and out of the way. The gaskets and seats I cleaned thoroughly and all looked in good condition so I re-used with a touch of o-ring grease. If I still don't get any luck in making it run well they will be on the list to replace. Thankfully everything came apart well and the job was surprisingly easy.
Almost finished re-assembly
I ended up replacing the rear crankcase breather as well as I accidentally damaged it whilst refitting the manifold. Thankfully I only live 20 minutes away from Britishparts
So with It all back together I started her up and there was very little improvement overall
Tickover is lumpy and it doesn't feel great when revved. I did get a video but looking at it now its hard to pick out the lumpiness. The only engine fault now though is for the front Lambda sensor which I am currently still waiting to turn up.
Do you think the faulty lambda could be causing the lumpiness?

Just tried that and it makes no difference. I plugged it back in after and restarted the car and on the OBD app I have it has a function for reading real time voltages from the o2 sensors. All read a steady 0.7v (cold engine idling) and dropped to zero when revved. Bank 2 sensor 1 however (the one showing up in fault) did not give any feedback to the software whatsoever so I think it must be duff. The new sensor should be here tomorrow so I will throw it in and see what happens.
I am just buying more bandwidth from photobucket so hopefully the pictures should come back soon

Fingers crossed
For anyone who's interested my spend tally is up to £805.23 all in so far, so I still have a bit of wiggle room should the worst happen. Current aim is to have a clean, solid and well sorted X-Type for less than shed money but I think that will be quite tight. I was originally looking at cars around the £1400 - £1700 range and they still all needed work of some description.
Hopefully the sensor will turn up tomorrow. So far the weather has been kind to me.

Still waiting on parts 
Tracking the main order on the post office site has shown that its in the Pesk District
Should have arrived on Monday.
I feel like every time i have a good days weather to work on the car the post office is holding me up

Well even though the rest of the bits I needed didn't arrive I fitted the new lambda sensor and had a play about with my diagnostic software.
Looking at the long term fuel trims on both banks seem ok at around 0.7 / 0.8v, and if I introduce a small vacuum leak by removing the brake booster pipe slightly you can see these drop to 0 quite quickly, so I am doubtful that there are any other leaks (unless the lower manifold gasket on cylinder 1 is letting by slighty?)
What are your thoughts? The possibilities in my mind now are:
-The new coil was duff and I should replace all 6 with new (is there any way to check these? There was no visible damage and none smelt burnt)
-There is an air leak lower down and I should replace upper and lower inlet manifold gaskets
-Fuel injector(s) not working correctly
-Blocked catalytic converter

Thanks I will check the coils that way before I put them back on. I have 8 now so hopefully I will find 6 good ones.
I have been having bad thoughts over the past couple of days, wondering if due to the radiator leak the previous owner overheated the car and cooked the head gasket between 2 cylinders (hence the lumpy running)
I have just pulled the inlet manifold off again this morning and done a compression test to check and settle my fears, here are the results:
1 - 198 psi
2 - 195 psi
3 - 198 psi
4 - 192 psi
5 - 192 psi
6 - 192 psi
Phew!
Thankfully all high and all very consistent. Now I know that the internals are good I am going to pop down to British parts and pick up new upper and lower manifold gaskets. Before I put it all back together I will also check that each injector is firing, the coils (as above) and that none of the wring looks damaged in any way.
I might also try to hook up some way to see each plug sparking. I don't want to take the manifold off again if i can help it
My spare MAF also got lost in the post so I need to hunt another down if the fresh manifold gaskets don't help at all. Fingers crossed!

Result!
Just had my neighbour turning the engine over for me whilst I was holding the plugs and coils against the cam cover, and sure enough I couldn't get any spark from cylinder 1's coil.
One of my spares did work so fingers crossed all will be better when I come to reassembly. If I still get grief after that I think I will replace all of the coils with new.
ETA
I checked the resistances before this and nothing looked untoward, all were much of a muchness

Well a bit of progress! As per the previous post I found a duff coil. Spurred on by this and the positive compression test results I went to British Parts and picked up some new upper and lower intake seals and also a rear ARB kit (was mentioned in last MOT).
Before I reassembled the engine though I wanted to check everything I could so used some kitchen towel to check that the injectors were all firing.
All ok so I cracked on with reassembly, making sure that everything was surgically clean
New vs Old
All done and I gave the engine a quick once over to neaten it up a bit.
So the moment of truth came and she started up and runs perfectly!
So the issue seemed to be that the new coil I bought was also duff, and also there were the leaking tuning valve o-rings which wouldn't have helped. Very relieved to get to this point though. I took it for a quick drive and it is driving fantastically. The rear bank o2 sensor came back up again which I was expecting so a new one is on order and then the engine work is finished. I am getting quick at removing the manifold now!
Tomorrows job is to fit the new rear brakes, drop links and ARB bushes. The list is getting very short

Got the brakes changed today, didn't get time to do the ARB bushes and drop links but I soaked all of the bolts in plug gas so hopefully should be an easy job for tomorrow.
Before
Old vs New. Uneven wear on the old pads so I made sure to clean and re-grease all of the sliders and contact points before reassembly.
Lewis' top tip of the day: If you (like me) forgot to go out and buy a piston winder you can use an angle grinder key
After
It only took just over an hour to do both sides. Everything came apart and went back together surprisingly easily. I like jobs like that.
The only issue I came across was that the handbrake mechanism on the right hand was a bit sticky so I will keep an eye on it. A new caliper is only £35 though so not the end of the world.

Couple of small jobs done today, and a couple of bigger ones to do tomorrow. I started with replacing the cabin filter. I ended up needing a puller to remove the wiper arms which was a bit of a pain but the job didn't turn out too bad in the end.
Before
After
As you can see I also gave everything a good hoover and clean out whilst I was in there.
Lastly I replaced the windscreen wipers as the old ones were not the best and I think its always a good idea before winter anyways.
These turned up too which I will be fitting tomorrow
I still need to get the ARB finished off but I doubt I will get time tomorrow, as I have to be at Jons by 3:00 to try and help fix his brothers X-Type he mentioned earlier in the thread
I also have a matching spare alloy on its way as there is currently no spare and its allowing the boot floor to sag down. I can see the original owner removed the old space saver and it is currently on eBay

400 miles in now and all has not been pain free. Although averaging 28mpg which is not too bad.
The caliper has been replaced and I flushed through the system with new fluid at the same time, but the pedal is still not as good as I would like. I will try again tomorrow.
I also replaced the anti roll bar bushes and drop links which took so much longer than they should have. Most of the bolts were seized solid and I ended up having to angle grind the old drop links off and drill out the remains. I cleaned and repainted everything before refitting though so it is a lot better under there now.
The last problem is that one of the new lambdas has failed already. Teaches me to buy cheap pattern parts
Progress though, at least she is driving

Forgot to add that I have also fixed my droopy drivers side headlight a month or so ago. The headlights are still not great so I think uprated bulbs might be in order.
Bumper off again
Looks like someone has been here before
I then split the glass from the light using a heat gun and removed the brittle broken adjusters
And replaced with these: http://www.ebay.co.uk/itm/Jaguar-X-Type-Headlight-...
Back together with Tigerseal and all refitted

So MOT time today, and of course it failed
-Bonnet cannot be secured in the closed position (New cable now on order £25. With a little wiggling around it can be closed but the cable is pretty much siezed)
-Headlamp aim too high nearside front (easy adjustment)
-Anti roll bar insecure nearside rear, loose nut marked (I can't see how I left a nut loose so am interested to see what has happened here
)
-Exhaust emissions (New DENSO lambda sensor ordered)
-Front brake binding offside front (I will remove the caliper and clean up / regrease the sliders and see if anything else is amiss)
The emissions if partly my fault after getting fed up with changing crappy pattern Lambda sensors. The one I had to replace on the bulkhead side did not work from the start, I complained and got another sent through FOC but this was also duff. Since then I got fed up and have just been living with the EML on, but now it is obviously effecting the MOT I have ordered a proper Denso sensor to hopefully get it sorted once and for all. I am not looking forward to it as access is horrible and last time I shredded my hands and was running out of patience.
So Lewis' tip of the day is DON'T BUY CHEAP LAMBDA SENSORS!
After I get 12 months ticket on it it will be up for sale, unless anyone wants to buy it as is?

Made a start on the MOT fixes today. First off was the bonnet cable.
Old cable with broken clip
New cable
I also took the opportunity to clean out the latches. I sprayed on some white grease before re-installation. Perfectly working bonnet release now
Next on the list was the rear ARB bolt. One was indeed a little loose so I must have missed that when refitting it
I also had a look at the front right brake which is binding slightly. I removed the caliper, checked the sliders which were fine but the piston was very tight to push back so it is definitely starting to sieze. A new caliper is now on order and since I know all of the bolts are free it should be a nice quick job when it arrives.

New Denso lambda sensor fitted today. Was a lot easier than I remember and only took an hour or so. The new brake caliper turned up as well but they sent the wrong side. They are sending another out but it means I cannot get into the retest until early next week now which is a bit annoying.
