Xantia V6 broken exhaust (update: and rough low rpm running)

[Northern_Mike]

Well after going fine for so long and only one small misfire event that was quickly cured with an OFF/ON of the igition today i was greated with this half way down the street...

" onclick="window.open(this.href);return false;

Needless to say its now parked up outside the house awaiting some news and then a decision from me as to what to do with it.

It could well end up being broken!

Oh dear, that's a poorly autobox if ever I heard one

[KP]

Yeah it's a dying one

Well it's say where it's sat now having to make another plan for Monday as I was going to go to Glasgow and recover another car that needs work!

Really sad to see the gearbox finally give up Will.

However this is exactly why I sold the car only as parts - when I told everyone I thought the gearbox was terminally ill and had a few thousand miles left I wasn't kidding around. I had observed the worsening of symptoms carefully as they progressed over the previous few months and estimated it had only a few thousand miles left in it and that it wouldn't last me until the following MOT.

I hate to be proven right, but it does at least confirm that I made the right call to go to all the trouble of buying the new V6, getting it all the way back home and doing the work/fettling it needed to get it up to scratch!

Jim - my hunch is the torque converter neck bearing has failed and welded itself to the torque converter shaft so that the bearing shell is now spinning in the casting - does that sound plausible for that type of noise ?

For a long time (ever since the first gearbox symptoms appeared nearly 2 years ago) it has made a strange noise under very particular conditions - usually slowing down in 2nd gear to about 10mph then accelerating up an incline - it would make a noise that sounded like a dry bearing spinning in its housing for about half a second as the torque converter locked up.

It made this noise in these particular conditions even back when the gearbox otherwise seemed fine and had nice smooth gear changes with no slip etc...

New V6 does not make this noise at all under any conditions, and the lack of this noise is one thing that made me comfortable that new V6's gearbox is in good order.

RIP Silver V6.

Well if the pump is fine then fingers crossed just a replacement torque convertor will so he job as they aren't too bad to get reconditioned but the replacement is beyond me to be honest so will keep my fingers crossed for other news

At least the fluid from it won't be that old and if it can't be reused in the box it will go into the xm

Glad it did it before I sold it to someone though as I hate that

[Mandrake]

I wouldn't reuse the fluid from it in another box - if the torque converter bearing has failed the oil will be full of fine metallic particles. I would never even reuse the oil out of a perfectly working auto box let alone a failed one..oil going into an auto box has to be absolutely spotlessly clean and new.

[KP]

Cool stuff just wanted to check it will get put into the xm then and used in it

[DHallworth]

Break it for spares so someone can have an Activa V6 again as I've got a shopping list of parts I need

David.

[KP]

Ha ha ha Mr H!!

And yeah it will be fine, the xm is like the Bosch xud's and runs on most stuff that's filtered and put in it it has two filters so nothing gets thru it and runs on engine oil and used veg sometimes

That will be precisely what's happened Simon.

Seen it now in most of the dead 'boxes I've dealt with. It can make the TC very difficult to remove and I developed a special puller for the job..

Nope, never re-use ATF. Burn it in the XM Will and make the exhaust sell of cat's pee

Actually, all the work that's been done on that engine makes it a good donor for a V6 Activa...

[KP]

Exactly Jim! If I could get small amounts from a local garage and had enough space to have a CHP genset I would have one in the garage plugging away into the hot water and power grid downside of a small back garden mind lol!!

Yeah fingers crossed it's not welded solid but let's see if a plan can come together and if not I'm going to struggle with it

[KP]

Well the final update has come.

After the torque convertor gave it's warning signs and I couldn't get a realistic quote from any locals that didn't require kidney payments I made the choice to let it go.

It went tonight to a nice Geordie fella and his friend who came to collect it on a towing dolly on the back of a 02 plate passat.

It turns out it's going to Iran via somewhere else so it's off there now. They said it might be broken down to go over there but hey ho it may help others live on...

[Hell Razor5543]

It's a shame you couldn't have grabbed the handbrake cables off it for Simons' new V6!

[KP]

They wanted a whole car I'm afraid and for the money I was more than to not take anything off it

[Hell Razor5543]

Fair enough.

[CitroJim]

An interesting end to this story Will..

I suppose Iran still has lots of their home-grown Xantias running around and a V6 conversion for one of theirs I guess is on the cards...

Thing is, as you caught it early, the 'box will be easy enough to fix...
