Well I've finally got the car home!

It's been a long time coming - but there has been a lot of work to do. And still plenty to go!

I spent day one just going through it, a preliminary jobs and drawing up the list of things to do.

First thing done though was the ignition system!

The old rotor and dizzy looked rather grotty! Plus there was no gasket between the dizzy cap and the rest of the distributor. There is now!

Image

So a nice new rotor and a good used dizzy courtesy of BrakeBuster have gone in.

There's a nice pile of paperwork and history with the car.

Image
Image

Including a free service voucher! I wonder what my nearest Jag centre would say if I walked in with that!

Image

Also found these rolling around in the boot, which are nice originals to have!
Image

Lots to do anyway. Plenty of rusty scabs and the suspension is still not right! Too high at the rear and too low at the front.

I guess if the front springs are toast - it could raise the rear? Maybe?

I have a set of used springs that came with my GAZ adjustable dampers - might get them in and see what happens. The existing springs are likely original.

excellent

looks like your maintenance is a timely catch to prevent future issues, and the Marelli system responds well to being looked after correctly , and top marks for the dizzy cap gasket, that thin bit of paper may seen trivial, but it provides a vital seal and spacing for the cap ,

you are probably aware, there is a vac pipe onto the dizzy going to a remote air filter ( that looks like an old fuel filter, and probably was ) this draws fresh air in to dissipate the buildup of Ozone inside the cap ( produced from electrical discharge ( lightening in effect ) , the Ozone corrodes the contacts prematurely , so a new filter will also help , the other vac pipe goes to the inlet manifold ,

and ensure your HT leads are in good condition as to prevent high resistance for the Marelli system, which it doesn't like

a good test for this is to fire up the car in the dark , and with the bonnet up look for any ' lightening ' inside the V12 well around the HT leads, and sparks of light indicate poor insulation on the leads

little and often is how i treat my V12 maintenance ,

Thanks for the filter reminder BB.
It was ordered with everything else from JCP, but I forgot it yesterday!

It has now been fitted.

Image

Old one was a little manky compared with the new!

I had a good look at the leads whilst changing the dizzy cap. I think they are likely original - like everything else. However, they looked ok - so will leave and monitor for now. I'll try your test method one evening too to check.

A little bonus was finding an engine cover screw in amongst the inlet manifold!

Image

Only two more to find in there now for a full set!

If "palmestery" was a "gift" of mine I'd see still more expenditure in future ... ;)

Well I've completed around 80 miles in the car as a shakedown and to see what's fallen off after so long off the road.

The good news is not too much!

Front springs have totally had it now - the tyres are slowly disappearing into the wheels arches!

Image
Image

I've currently got 61cm from the garage floor to the wheel arch on the front and 69cm on the rear. So it's looking a bit like a drag racer at the moment! Out of interest - what is the normal ride height for the V12?

I have a pair of decent front V12 springs - so they'll be getting changed over when I get back from work in a couple of weeks.

Also found a couple of coolant leaks. One on the radiator that just needed tightening up: -

Image

It's the small metal connection under the top radiator hose - I'm not sure what its for. However, it was nearly off and has covered the front of my engine bay (and garage floor) with red coolant! Can anyone tell me what that connection is for?

And the other was these bleed hose connections on the expansion tank: -

Image

It looks to me like the rubber has perished and blown - so will try and get new hoses and see how that goes. Hopefully it's not that expansion tank failing.

Anyway, its getting there - slowly but surely.

the ' small metal connection ' under the coolant hose is your transmission coolant circuit , there is a separate core in the coolant radiator for the transmission cooling, so you will need to check the level of the gearbox fluid as you have had a leak

otherwise, all good news
does the car have SLS at the rear ??

keep at it

That's again BB for the info.

The car doesn't have SLS - so no worries there.

I'm away with work now, so I'll give the gearbox fluid a check when I get home in October.

It's been a good start for the old girl - but its tucked away now in the garage keeping dry.

I look forwards to continuing next time home.

Good progress Richard.
There’s always plenty to do on these, and am sure the list will be added to as you go over the car.

Clearly the front end of the car is extra heavy on the V12, but the sinking front end is rather unusual. Don’t forget you will need the proper spring compressor to change the springs. Do no not attempt removal without researching it on here.
The other thing that will likely come about. By the time you have the springs and shocks off the car, you may well be looking at rebushing the front end. There’s a good change they will all be last their best. Unless you know they have been recently renewed already, which I think is unlikely.
Top shock bushes, upper and Lower wishbone and Vee mounts, but you may as well renew the anti roll bar bushes too. It will be obvious when you get it in the air and have a good.

How did it handle on the test drive them?

Hi Naki.

It had GAZ dampers and a new thicker roll bar off an XJ12 fitted before collection. They all had new bushes on fitting.

The front springs were not changed - but will be now. Got to admit - I won’t be doing that one as it sounds very dangerous to someone inexperienced like me! Keith at XJ will be handling that and the wishbone bushes - as the car is not far off undrivable.

However, the initial drive home and around was encouraging. The updated dampers really give it good control and take a lot of the roll out round corners. They are adjustable - so will be playing with them somewhat to get it exactly where I want it.

The engine and gearbox were good. I had to adjust the play in the throttle linkage as the pedal went half-way to the floor before the engine reacted. The gearbox is nice and smooth - smoother than the Sovereign I'd say. The engine has a nice kick and sounds great. There is a slight ticking noise from the ignition when its cold - but goes away once warm. Normal?

Changed the tyres and had the alignment done a few days ago too - so not bad and it at least goes in a straight line now.

Still got plenty of water damage and corrosion in the front footwells to sort out. I've wire brushed it all back and treated it - but I think more serious stuff will be required there.

Anyway, I'm looking forwards to trying it with a sorted front end!
