All Things V6...

[DHallworth]

Does anyone happen to know where I might be able to find the gear ratio's for the gearboxes fitted to the Xantia Activa and the 406 V6? Manuals obviously.

Do the standard Activa driveshafts fit the v6 gearbox?

Sounds like an interesting project David....

Not wanting to put a dampener on things, but best off talking to your insurers first - or casting about for someone that will insure it. Most insurers take a dim view of this sort of thing, and insist on engineer's reports and huge premiums. Of course, I can Write CEng after my name, could write you an engineer's report - I am normally let loose on huge process plants, so a V6 conversion should be easy enough... Insureres might see it otherwise though

Well I've bought that Xantia V6 this morning so we'll wait and see how it pans out when I get the car home.

Excellent David. I'm looking forward to following the project too.

And I know exactly what you mean about how much fun the Activa is to drive. That's why my V6 is on SORN and the Activa isn't...

All the best with the project, should keep you out of trouble for a while Though don't forget to put that V6 Xant back together when you've finished with the engine in the Activa! 122 left at last count!

I've been thinking about this but the problem is you'd need an auto box from a 2.0 Xantia. The 2.0 Xantia Exclusives were 16v engines so I'm not sure how the box would take to being on the TCT engine.

The other option is that this Xantia V6 could provide a lot of spares for people that need them.

Indeed... I was thinking last night.....Simon (Mandrake) has a V6 that's otherwise good with a probably poorly gearbox and unknown cambelt history, David has a V6 he's going to take the engine out of, David has a workshop... 2+2=5 V6 engine out and in, with box change and new cambelt and cam boxes re-seal in a (long!) day? A FCF engineering meet W of Glasgow? I'd be in

[CitroJim]

What an excellent idea Richard

Given some accommodation nearby I might be tempted to come along too. Quite a trip but all in a very good cause...

[DHallworth]

Well I've got the V6 Xantia home now.

Few things wrong with it:

ABS goes nuts at crawling speed when coming to a stop.
Front offside wheel bearing is noisy
Seal around the windscreen is broken
Someone has run a key down the drivers side of it at some point and there's general scuffs on the bumpers.
Sounds like there's a noisey tensioner/idler on the aux belt circuit, suspect the air con compressor as it's worse when toggling the A/C switch.
Over 180 miles home the engine temperature didn't rise about about 62 degrees. Suspect someone has removed the thermostat but will check the sensor with Lexia.

However, apart from the above the car drives very nicely, it's quiet and smooth and was effortless on the way home.

The chap I bought it from was a mechanic at a Citroen/Peugeot/BMW/Mercedes specialist in Newcastle. Apparently for the last few years this has father has owned and run the car. He also told me that they'd done some servicing on it for the chap who owned it before his father. He also told me the chap who owned it before his father changed the gearbox on it.

I noticed when sitting in traffic leaving Newcastle today that the car occasionally jerked/banged it's gear changes from 1st to 2nd and 2nd back to 1st. It didn't do it every time but it did cause concern.

When flooring the car past a couple of lorries on the A69 it kicked down brilliantly and flew through the revs. I sat doing a little over 70mph with the cruise control on coming home and the pin says it's used just over 1/4 of a tank of fuel to do 180 miles.

All in all it's a nice car in a much better condition then I expected it to be in for what I paid for it. With the banging when changing gears I'm convinced it's the right car for what I want it for.

Will post some pictures of it up when I get a chance.

David.

Abs issue at crawling will be a snapped or rotted away Abs teeth ring on the cv joint...

Yea, I thought that as we had that problem on our HDi too.

HP20s are a bit prone to second/first banging David. Nothing really wrong with the 'box. Often a re-initialisation of the auto-adaptives fixes it...

Where is it you go in the Lexia menus to find this Jim?

Ahh. Not where you think David. It's in the Spare Parts* area and not in Diagnostics where you’d expect it...

Go into Automatic Gearboxes. Choose ZF 4HP20 and Reinitialise Auto-Adapttives.

Then go for a very varied drive.

* I can't remember exactly the precise name of the menu but it's a couple or so down from Diagnostics on the front page of Lexia.

David ... was this car at Centreville Garage by any chance?

Yea, it was. Do you know the car?

David.

We know Centreville
Generally excellent reputation.
