Cherry Blossom - Restoration 1990 XJS V12
Braking Bad (Part 3)
Retro Fitting A 'Non ABS' Retro Brake Booster System in my 1990 XJS V12
So how easy was it really to change from ABS to Vacuum Booster?
This was one of the easiest and most fun jobs I have ever done on my Car, it only took me a Couple of days where the main hold up was trying to buy things like Brake Pipes and Vacuum Hose, as in the UK there are very few places that sell any of that stuff unless it comes Hermetically Sealed in a little plastic packet!Retro Fitting A 'Non ABS' Retro Brake Booster System in my 1990 XJS V12
So how easy was it really to change from ABS to Vacuum Booster?
So if it wasn't for places like ebay and also Amazon where would we be?
But actually fitting the Booster was a bit of a 'Walk in the Park' so easy to do and so much fun as the pay off could be amazing if I can get it to work although I haven't had a chance to even drive it round the Garden, as it has been more like Winter than Summer and chucking it down with rain
Greg was right about the Tube as well as everything else, although I did try and get the same as was shown in his Photo, so on Monday I'm going to order some more from that other Store that he gave me a link to
So all there is left to do now is tie up some loose ends like that
Together with the Brake Light Switch which is totally different to that on my ABS Car, which is going to be a very interesting problem to sort out
To be Continued.........
Exhaust Bodge Fixed At Last!
Today I managed to do a Job that has been on the 'Back Burner' longer that I ever care to remember, which was Fixing the 'Droopy Exhaust Pipe' on 50 Shades, my Grey XJS and all down to a bodge up by either the previous owner or the Shop he took it to
If you think that looks 'Crazy' then you ain't seen nothing yet! Just wait till I take it apart
This Exhaust Pipe was joined in Two places by Clamps, instead of just the One so maybe not so surprising that it 'Drooped' as much as it did 'What were they thinking'
And come to think of it what was I thinking to put this job off for so long, as there were occasions when the Exhaust would bottom out, which could have torn it straight out of the Car 'No Skills and No Welding Set' is my one and only excuse and I didn't want to take her to a Shop
Having 'Migged' one joint up, it should go on with One Clamp, instead of that 'Crazy Contraption' that held it all together underneath
Trial Fitting the Exhaust Joint, which seemed to be ok
Holding the Exhaust in place, while I did up the Clamp
Looking Good, as the Exhaust Pipe I repaired is now higher that the original one on the other side of the Car, which will probably drop down to match after a bit of a run out in the Car, this repair took half a day but would have been a lot quicker if only my Car Lifter had been free
My plan is to have 1 xpipe muffler installed and the exhaust exit in front of rear wheels with flat tips.
Acceleration Hesitation!
Having Finally Fixed the Bodge on the 'Droopy' Exhaust Pipe of '50 Shades' my Grey XJS I thought that I would take her for a 'B' Roads Test drive just to see if the Exhaust would hold up without falling apart
Before!
After: where the 'Droopy' Exhaust Pipe (nearest in the Pic) went back even better than the OEM so what could possibly go wrong!
Having now Fixed the 'Droopy' Exhaust and when I Started Her up, the first thing that I noticed was a Change in the Exhaust Note, which was a bit more of a Roar than a Purr although apart from that things seemed quite normal, until that is I took her on the road!
Where when trying to accelerate from a Standing Start, instead of the Smooth Take Off I was used to, the Engine seemed to misfire for a micro second just like I was hitting a flat spot in the power curve, only very minor and hardly noticeable but all the same that hesitation was there
So back to Base to take another look, where upon inspection I could clearly see that I had put the Sealing Ring in Crooked
The Crooked Sealing Ring was the cause of the problem but even so who would have thought it could make that much difference, apparently Not Me!
Lining up the Exhaust Pipe on an XJS is not exactly a 'Walk in the Park' to get perfect
After much Jacking and Pushing and Shoving, I finally got it lined up and the Acceleration Hesitation Vanished!
So if that happens on your Car, the Exhaust System could be a good place to look
Very nice work.
I did get a video of my exhaust sound but afterwards I realized it was at high idle so not very good lol. Yhen got into looking for problems with tranny...conclusion is im taking out the tranny. First time for me so should be fun. Gonna be a couple of weeks before I drop it though.

'Fangirling' Over '50 Shades' My Grey XJS
After Weeks in 'Lockdown' unable to go out, they finally took the Brakes off just a little bit, so that we could go out for a Picnic, which is one of the favourite things that me and the GF have always loved to do and you couldn't get a better day than Saturday June 20th as the Weather was perfectNice and hot and Sunny with Cotton Wool Clouds in the Sky and '50 Shades' in Garage but not for much longer, as while the GF got her gameface on and packed us up a Banquet which included Strawberries and Whipped Cream, I was whipping the Cover off '50 Shades'
Which was a moment that I had dreamed of for Weeks!
That up until now had been a case of don't look and don't touch, as doing either would have been too painful, as '50 Shades' hadn't been on the road since being put in 'Mothballs' last September
Then as the last cover fell down to the Floor, I was literally blinded by her beauty, I mean it was one of those moments when I went, Wow! Just Wow! was I a lucky So and So, or What! as this is a Car you can Fangirl for all you are worth
I was so excited that I could hardly breathe, as having done the Pre-Flight Checks and Topped up all the Fluids, I opened the door on the drivers side and sat down on the Connolly Hide and then felt that rush of Adrenaline as I then inserted the Key into the Ignition and having done so turned it to position one
At which point I heard the Brake Pump pressurise the System with the Sinister Rasping Sound of a demented Ghoul, which could have been the Stuff Nightmares were made of that sort of gave you a feeling, that something definitely Wicked was about to come this way!
Where with one more turn of the Key the V12 burst into action, with a Turbine Howl that sent a Shiver down your Spine, as I snicked her into reverse and backed her out of the Garage into the Morning Sun
Where She seemed to look even more Stunning than She ever did before, in a really drop dead gorgeous sort of way
Picnic Packed! and GF looking 'Cookie' or should I say off the Wall, with a mop of Yellow Hair that came out of a Bottle, which sort of looked okay in its own way, once you had managed to get yourself over the Shock!
Where once having managed to do that, I slowly backed the Jag out of the drive of 'Orange Blossom Towers' onto the Tarmac, where She sat there purring like a kitten, while I was feeling like a Cat that had just got the Cream!
As I looked into the mirror and saw the whispy plumes of what was looking like a heat haze coming from the Tailpipes like a Jet Fighter sitting on the Runway, so now with the Shifter clicked into 'D' we were off!
Where the Purr from the Pipes turned into a Roar as '50 Shades' went zooming down the Two Lane Blacktop like a Missile, where just in case you were wondering it just doesn't get better than this, 'We were living the dream!' and about time too! after being off the road so long
As we headed out into the Forest for a Grand Day Out, where '50 Shades' just did not disappoint, as we wafted along in the Sunshine as smooth as silk on our own Magic Carpet, until we finally arrived at out favourite Picnic spot, with Rustic Chairs and Tables scattered all around this lush green forest
Where we both spent the most wonderful day that you could ever imagine before finally heading for home and now with the Weather about to heat up, we're planning our next trip, so all those less important jobs at 'Orange Blossom Towers' will have to wait until it rains!
'DD' Saved The Day!
Hi JackYes! it was a Great Day Out!
With hopefully more to come, as the Weather is due to get Hotter!
Which is a cause for Celebration here in the UK as days of unbroken Sunshine can be few and far between and sometimes it even gets too Hot to go out!
But when We got home, I realised that our grand day out, could have easily ended in disaster, as while collectively helping another Forum to get their XJS back on the Road, Doug came out with what I thought was a really great suggestion which was to test the fuel pressure on the Engine side of 'A' Bank FPR
At which point I thought I'd take a Photo to clarify that Area on my own Car '50 Shades' which I didn't take much notice of to start with, as I just took that Photo and put it in that Post
And here it is:
Look just to the right of that metal clip after that Top red Arrow That hose has been nearly cut through!
No Prizes for guessing what could have easily happened and no doubt would have done so any time soon but thankfully I also had a Spare one in the Shop, that I must have collected on a visit to a Scrapyard, as I thought that one day it might just come in useful and 'It did!'
So bad it looks as if it had been Weeping, which no doubt is what I would have done if '50 Shades' had gone up in Flames!
Counter Torquing the Connection that was really hard to undo!
Got it off at last!
The one on the 'A' Bank FPR came undone quite easy
Yikes! it looks even badder from this angle
Spare Pipe ready to go back and having put it on, I then made a Short Video to convince myself it wasn't leaking!
So Massive Thanks to 'Doug' for Saving my Car from potential disaster!

Ob
Do you mean those scalloped-out longish shapes in the hose?
If so, pop dobs of grease on the hew one and close the bonnet tight. Then open and look for grease on the bonnet, just to be sure they problem is not caused by something rubbing on the pipe.

Hi Greg
Cheers!
I never thought of that!
Could well be some sort of abrasion as you said
But when I take the Car off the Road in November, I am planning to replace all of the Injector and Fuel Hoses and also Cut out the FPR on 'A' Bank even though She is running quite happily with it Connected
I can get my Hydraulic Shop to make me up a Pipe, with Two Female ends to 'Bridge the Gap'
Would that be the Best way to go?
Cheers!

Hi Greg
Okay Thanks
Do you have the size of the Top Quality (Gates) Injector Hose that I am going to need as my Hydraulic Shop has a special machine to cut it to length rather than pay £100 for a Kit

OB, the hose ID I forget, sorry. But there are no special tools needed, just cut it with a knife. Both ends just push onto barbs with hose clips as in my photo. If you are getting a swaged hose made up as you originally mentioned, then the place doing it can measure the ID you need. But it has to be petrol proof hose. If you are supplying the hose to them, cut the old one in half and measure! Then buy what you need.
Hi Greg
Cheers!
But I think that getting a Hose made up might be the easier option in my case, as then I can leave the disused 'A' Bank FPR in place as it is
Stop me if I am doing this wrong but when I replace the Injector Hoses, can I do this without the need to remove the Injectors by cutting them through half way up and then removing the Fuel Rail
Then Carefully cutting what's left of the Pipes off both the Fuel Rail and the Injectors and then putting all New Injector Pipes on the Fuel Rail and then pushing the Fuel Rail with the New Pipes, back onto the Injectors which will still be in place in the Car

Hi Rescue
Its FPR which is the Fuel Pressure Regulator
The only one that's needed is the one on 'B' Bank and the other one on 'A' Bank can be taken out of the Circuit as it isn't needed and the later Cars don't have them
The Fuel Pressure Regulator has a Rubber diaphragm which acts like a 'Dam' that holds back the Fuel in the Rail until the Correct Fuel Pressure is achieved before releasing any excess back into the Fuel Tank, as I'm sure you know, so just throwing that out there for any newbies

My real point is that if the hoses are shot, so will be the seals the injectors push into, so in your place I would pull one injector at a time and do all the seals, change the little basket filters in the injector inlets, if they need it.
