Yeah I was fully ready to stick the head back on. Would have been a total waste of time and I’d have come to the conclusion something was cracked somewhere in the block. Probably explains the slow coolant leak I’ve had for the last year or so with no evidence where it’s been going. 🤔 weeping through and steaming off in the oil.
Have you tried running a diagnostic on the AC system. Here’s some instructions I copied! To check for error codes in the Climate Control System with the internal diagnostics via the ‘Panel Codes’ 1. Ignition off - hold down AUTO and RECIRCULATION buttons and switch on the ignition 2. press AUTO button - if ZERO shows, there's no stored error codes 3. Press the RECIRCULATED AIR button to start diagnostic, sequence will start to test system. 4. press FACE button repeatedly to scroll through stored fault codes 5. press FACE and HEATED REAR WINDOW buttons together to clear a fault code. 6. repeat step 4 if there's more than one code 7. press FAN button to exit Interrogation Procedure .
Mine wasn’t going into CL a number of years ago and if I remember it was O2 sensor related. Ended up swapping them. Most of the cheap standard code readers will read the live data from the O2 and fuel trims. Usually one is just pinned.
@@chrisbaker121924 I bought new O2s from britishcarparts and drove the Service drive cycle many times. I also swapped the connectors (firewall). Some say without the Jaguar programming that the car will stay in OL. What do you mean by pinned please? STFT is zero. LTFT is 1,27 V at idle, decreasing when I hit the throttle. Thanks mate 😉💪
@@neindochoohh7955 by pinned I just mean right at the extreme end of the range it can read. Can’t say for sure but mine didn’t need any codes afterwards clearing. The other issue you could have is with fuelling. Perhaps some vacuum hose is split. I’ve had that issue a couple of times with hoses going into the inlet manifold being split and it’s caused issues with fuel regulating etc which in turn affects the lambdas.
@@neindochoohh7955 it will be something simple. :) they’re simple cars. Possibly worth cleaning the MAF sensor? If not then yeah probably need to adapt the O2 and TPS.
I bought a English import jaguar X300 and after repairing a great deal of ignored problems from the previous owner the car started losing oil. After looking where it comes from I found out that the head gasket failed which unfortunately is probably the death sentence.
Not too bad to fix if you have a socket set and some patience! The gasket kit isn’t expensive. If it’s a nice car it’s worth the effort and if you’re not too handy with the tools now is a good time to have a go :) Mines been done now all this time and it’s running perfectly.
Fab video as always. Never would have guessed it was that cover causing all the mischief! Can't wait for part two...

Great vid as usual Chris!! Looking forward to seeing it back together! :)
Thanks :D me too!
Can you review the middle A/C vent not blowing air but the sides are blowing air. How to get to the mechanism?
How do you mean? Like the actual vent in the centre isn’t blowing?

Lovely car and video! Too bad that my 4.0 isn't going to closed loop and I don't have a VDU/IDS to adapt the O2-sensors

@@chrisbaker121924 I sprayed all with brake cleaner while the engine was running. Nothing. I love the car but its also a nightmare

The engine messed up so bad it caused the steering wheel to move over to the right
😅… it’s in the UK and it’s a British car so… that’s where it’s meant to be!

It was funn driving it around 4 months thought

@@chrisbaker121924 yea but time is a factor.
It will be another 300€ parts and it's time consuming.
I also hate working with timing chains
