Thank you, your right. A clean pass is more than i expected, 8 years off the road and the last two restoring it to its former glory and taking my time and checking and double checking but brakes performance and emissions we cannot check at home and i expected to have a small blot on the copy book but i am really chuffed to bits and that was reward for all the hard graft.

Best regards
Gary.

How about treating us to one last full size picture of her at her best angle? You decide which ;) .

I do apologise, i didn't realise that it was last August since i have visited the forum. Its not intentional, i suppose too many cars to look after and life gets in the way some times.

But an update on the re-birth project, after passing its first mot after nearly 8 years with no advisories i started using the Jag almost daily for my commute to work which sadly is only a 12 mile round trip but very satisfying. I forgot just how nice a really well sorted 40 drives and i use it whenever i can, however since December its been tucked up in the garage mainly to the horrible weather and road muck but it did live outside up to this point and we did experience quite a bit of rain in that time and the car was completely water tight with no leaks into the foot wells or any ware else for that matter. :D

1400 miles under its belt so far and there have been a few small issues to deal with. Firstly an oil leak developed from the oil cooler pipes where they meat the engine block but that was my fault for not renewing the O rings, easy fix. Next the alternator belt started squealing on start up and this was down to the adjuster fixing bolt coming loose, maybe i didn't quite tighten it enough, i'm not sure.

Next the small water pipe that goes to the thermostat split right in front of the securing clip causing a slight weep, bit annoyed with this as all rubber hoses in the engine bay was replaced with new.

The rear suspension has developed a small annoying squeak which is going to be fun but this will have to wait until spring and is probably due to the car being laid up for so long and one or two bushes drying out, major rear suspension service coming up then. :shock:

Lastly the most annoying thing is the rear passenger wing that was sprayed last has developed a small area of micro blistering, i know what causes this and i thought that i had been very careful, so that's going to have to be resprayed. I will post a picture up when i get the car out next. its not that noticeable unless you look down the length of the panel and most would not know its there but i do and its really annoying me. :evil:
I could leave it but in time i think it will only get worse.

Apart from that its been an absolute joy and the response from joe public has been amazing even thumbs up from modern Jag drivers :D

Fuel consumption locally is between 20-22 MPG and up to 29.3 on a motorway run.

All in all, pretty happy.

Best Regards
Gary.

Sounds great, Gary. What is the cause of micro-blistering after a respray?

Great update Gary. Overall that’s excellent news.
It must be very satisfying to finally use the car after quote so long?

There’s always niggles to attend to whether they are used or not used.
New hoses splitting is disappointing. I suspect the quality of the rubber used on them is no where near that of the originals.
In my experience most of the hoses tend to be reliable, except for the notorious one off the back of the water pump.

Rear suspension squeak- did you fit new shocks by any chance?

Hi Aidan,
the micro blistering is caused by moisture which is a little bit confusing as its not affected the whole panel which was painted in its entirety, i'm thinking that some moisture may have got through the gun while spraying even though i have a moisture trap but its still not impossible. :o

Best regards

Hi Naki,
thanks, i was expecting some niggles and a lot more than i have experienced after the Jag was so long in slumber :lol: but i did try to make sure that i went through everything i could think off but we all do like to be perfectionists don't we :?: it was a damn good try though.

Your right, it is so satisfying to use the Jag and after getting it back on the road i have have realised how enormously i have missed it. I've driven a few Rolls Royce's and a well sorted 40 drives just a nice, smooth and seamless. I still don't tire of the smile it puts on my face every time i get in it and of all the cars i have owned this is the best by far.

Parts quality these days is definitely questionable and it seams to pop up a lot these days in magazine articles.

The rear suspension was largely untouched as was deemed good to go as were the shocks, have i missed something here :?:

Best regards
Gary.

The rear top shock bushes are completely out of sight, for any visual inspection. If there’s no noise, I would say fine, leave them. But with any kind of knocking/ squeaking at the back end, I would look there as one of the main suspects.
If you do some searching on here, you will also see a number of posts showing wear on the upper shaft where it cuts through the upper Bush, and starts running/ cutting through the top mount plate. “They all do that sir”.
I would not say it’s an urgent issue, just another wear and tear item for the list.
Another logic might be that by the time you have taken it all apart go change the upper bushes, it may be worth fitting new shocks to future proof. If they are original, it’s always possible they may be past their best.
They may have been replaced before on the last though.
Good quality shocks are long lived on 40. But nothing lasts forever.

If you inspect the rubber gator on the Lower bushes (Spherical Joint as jaguar call them). This often gives a good idea of the overall age/ condition of the shock. Most originals are splitting/ have split there. If those need changing, you are in the zone of spending the same amount changing two bushes, as a whole shock.
I hope that helps.

Hi Naki,
thank you for the in depth explanation, this is most helpful and has certainly given me some pointers at where and what to look for and could save me a whole lot of grieve.
i have seen the post a while ago about the upper shaft cutting through the bush due to wear, frightening. However the Jag is not showing signs of this or any heavy wear just an annoying squeak over some uneven road surfaces but i will have a thorough investigation based on your recommendations.

Best regards
