Default Re: What is happening

Figured it was time to stop cowering in fear and actually open the bonnet of the Jag again.

No huge surprises to be honest (and it is just as terrifyingly complicated as I remembered). Hasn't used any detectable amount of oil or coolant on the trip home or driving around yesterday which is nice to see.

Quite a lot of surface corrosion on everything which fits given that the car has barely been used for a not insignificant number of years. Oh, and the air conditioning belt is not fitted as we were already aware.

Slightly intrigued by the little red anodised cylinder by the nearside brace.

In the absence of anything to suggest the contrary I'm guessing this is either a filter/silencer or a check valve attached to a vent line of some description as there doesn't seem to be anything nearby which could connect to it. Guessing the original unit died of old age. At the very least this one will get painted black as it currently looks daft.

Looks like the distributor cap will be "fun" to change.

The HT leads at least seem to be relatively recent - based on how supple they feel anyway. Even though it will be an utter pig to get to, I'll probably change the cap sooner than later as it's the sort of thing I usually do as a matter of course on any new car.

The throttles definitely need balancing I reckon. Just based on how much air it feels like is being pulled through each of the air intakes it feels like the left bank is doing far more work than the right.

One fault I had noticed right back when collecting it was that I only had one functioning reversing light and that looked very dim. Quick examination revealed a dead 21W lamp in one side and a 5W one in the working light...explains why it was so feeble. Nice easy fix.

Helped by Jaguar having used stainless steel fasteners on the light clusters...oh how I wish Saab did...

Oh, and for the record, the engine isn't running in the above photo, it's just in reverse with the of ignition on...I don't trust the handbrake enough to get out with the car in gear and engine running.

While in the area of the rear of the car, I'd noticed that the courtesy lights in the boot didn't work. Turned out they were both disconnected. Reconnecting them restored full functionality.

Confirmed they're switching off (and staying off) by sticking my phone in there and recording video while I closed and then generally messed around with the bootlid. The photo makes them look brighter than they really are though, they're a bit feeble to be honest. For practical reasons these lights may have warm white LEDs fitted in due course to increase their output to useful levels.

The oil pressure gauge sender was investigated while I had the bonnet open (I still love the opening/closing action and the way the latches pull the bonnet closed when you reset the handle). No part numbers I can see on it.

According to the former keepers this was ordered correctly based on the chassis number...and they're reasonably confident that the issue is with the instrument panel. So this will require further investigation.

The other issue which has come up requiring actual immediate attention (electrical, no surprises there!) is that yesterday afternoon the previously dead illumination for the tape slot on the stereo suddenly sprang back to life. However it then resolutely refused to go out again, being totally unaffected by anything else. I gave it the benefit of the doubt and decided to see if it would go out after a while on its own. Did it?

That will be a no then. The red LED is fine, that's the immobiliser fob detector and is allowed to be blinking away. So for tonight I've pulled one of the battery leads. On the plus side this takes five seconds to do because it's in the boot. I'll try to investigate that tomorrow. Hopefully it's not a serious problem with the head unit (which otherwise seems to function perfectly) and can be easily resolved.
