At least it's not the ZF6 they are a PITA to repair.

Parts should be plentiful for ZF5HP24 in the EU. Good Luck

 

If I'm really lucky, I can get away with a like €200 repair with removal and refitting by myself...

 

The engine is turning into an engine again!

Intake manifolds are fitted. Cleaned first, then fitted with new gaskets and nuts and washers, then new vacume take offs, new clamps, new balance pipe and co...

 

I'm envious. There's no emote for it. I looked. It would be a picture of your motor, then mine, then me, looking envious.

Would you take a nice square shot from directly over the motor while you have it in that state?

 

Sure can mate... Just straight from above from front or from the side?

 

Thanks Daim!

Straight overhead. Straight down would be great. Really hard to find a clean shot like that! Especially not all plumed up. Sure would help me out. I'm planning my own adventure.

 

Will this do?

I have no worry letting people use it as long as it isn't commercial!

 

This is excellent! Thanks Daim!

 

I've been using my 'internet mechanical genius', as Al Whitelock calls it, to overhaul my cruise control unit... I mean, there is loads of information on how to do this...

Just waiting for the housing parts to be galvanized, and then I'll be rebuilding it. The first parts have been reassembled. I'll be going the new cable way, with a custom made one (because I use my internet mechanical genius, I'm too stupid to make a cable myself) to my specs.

Just not sure yet if I will maybe adapt it to pull from a different area or not...

But, the wiring inside (and outside) is of course totally brittle. Will be replacing that. Just need to figure out how I can rebuild the plug. it looks like it has the standard Lucas style connectors (2 male, 1 female). Shouldn't be a problem to rip them out of the rubbery plastic (I assume it is PVC) and fit some new ones... The rubber connector/grommit between the inside and outside (sealing it all) is in good condition, so I'll be reusing it, just putting a dab of silicone around the areas, to make sure it is totally sealed.

The sticker on the front is a worry though. I am so fussy, I want the sticker to look exactly like that one WITH the same serial number. The ones available are from a different brand and don't have my serial number...

 

Well then Gents (and maybe the odd Lady )...

'Tis Easter, means bank holiday and a break from the new job I started on Monday Decided to work on my V12 (the 5hp24 out of the XJ8 is all overhauled in sorted with some Audi parts... So it will last A LOT longer - if interested, here is the thread in the X308 section just need to refit it).

A few months ago, I took the throttle bodies apart to have some of the parts galvanised. Now it is ready to reassemble. The lever arms and other parts are now in a pretty yellow colour (again). As close as possible to the original cadmium yellow. All rubber (the two lower bushes) are originals. The aftermarket ones LOOK identical and have the same outer shape, but the difference is in the diameter of the rubber ring which sits in the opening of the bracket on the intake. That is about 3 mm larger and the original ones (a lot harder rubber!) are a tiny bit smaller...

I didn't replace the bushes in the TBs themselves, as they weren't loose. Nice and tight. The spindle is the old one just like the butterfly valve. Just cleaned them up. The valve only fits in one position as I had to find out... New rubber seals around the TB of course as well. Don't want an air leak at all.

Also set up the TBs. German manual says the flaps/butterfly valves need a 0.05 mm gap. So I used my feeler gauge... Otherwise it clicks nicely (see video below).






























And the video of how these links all work together... Just so those who don't have a V12 know what they are "missing out" on

 

Had to share these. All parts refurbished with some nice zinc plating... The fuel rail is not perfect, as the welds around the injector conections were bad and seemed rather corroded, but the overall outcome looks nice! The ATF pipes look new, just like the injector clamps. The fuel pipes aren't perfect, so I might be looking for some new ones instead... Was worth a try.

 

Your engine is a work of art, I love the zinc plating.

They sell "do it at home" plating kits that I've been tempted to try, but it is hard to say what the level of quality can be when compared to a professional job.

Is that a stock fuel rail? It looks quite different from mine.

 

Cheers mate! These parts are done by pros... Espcially since they use acids and other chemicals to remove any kind of "crud" off of the surface.

 

Daim:


1. Just far too pretty to hide under a bonnet!!!


2. But, a bit of concern. Are the screws that secure the throttle butter flies
staked ? I've done that in other critters, and the brass screws had a split end to be bent over.


Carl

 

They have the slot in the middle but aren't long enough to be bent over. The original ones didn't either...

 

Yes that's the HE fuel rail with barbs and hoses. Your 92 will have the later fuel rail with O ringed injectors, NO MORE hoses to burst.

 

I like the gold Chromate finish it looks very OEM.

 

Cheers Warren. I want the OEM look. Some of the finishing isn't perfect, as already said, so I might actually go over it with some yellow/gold paint yet...

 

Daim, really love all the pics! Looks great, and they're a great reference for all of us who haven't had all those bits out yet!

Each exposed rubber bit you show I'm thinking "need that".

Love the attention to detail and going original look you won't go wrong as some restos do. Are you going fully Original in the engine bay? Replacing stickers etc?

 

I did my own zinc plating using what could best be described as a home "kit" and so long as some attention is paid to the preparation the results are flawless.
I don't have too many pics of individual bits but these may give you an idea at least.
