Roffle Regarder Xantia tombola - Tickets £6 ou 3 pour £15

Timing belt jumped a couple of teeth is very likely.

Is the aux belt still on?

[explosive-cabbage]

Sounds like it has a bad case of Banana Transit!

 

Could be pump or pump timing, difficult to tell from the video, but it sounds awfully clattery!

 

I'm not sure about the symptoms, they are not ones I am familiar with!

 

Some questions:

 

Was it a partial engine seizure or was it more fuel related do you think?

 

Is there still plenty of compression when you turn it over?

 

Does it run better when revved hard, or whilst idling?

 

Is there any oil leaks?

 

What is the oil level like?

 

Does the oil smell okay, or does it smell burnt?

 

Does the black smoke smell like fuel or oil smoke?

 

Does the fuel grenade feel spongey? If you squeeze it really hard with the engine off you can find fuel leaks in the engine bay by listening for escaping fuel.

 

Is there a slight rattle from the crank pulley when you turn it off? It may be a loose crank bolt, causing the woodruff key to wear the slot bigger in the pulley and put the engine slighly out of time.

 

There was some quite bad wear inside the fuel pump last time Graham had it open, caused by little flakes of metal. Might be somthing to do with that.

[explosive-cabbage]

It is very unlikely to have skipped a tooth, it was properly timed and the tensioner set up right.

 

We didn't contaminate it either when we did it. If you want me to check engine timing get it up to my spot and I can do it in about half an hour!

[The Moog]

Will have another look tomorrow to see it is anything obvious. If not might get local Citroen guy to have a look, he won't charge if he can't fix it.

 

No not been thrashing it at all. Don't go over 4.5k and top speed is 80 mph. Mot garage knew and didn't rev it. If I had I wouldn't mind the mpg!

 

Didn't touch any of fuel settings on pump as didn't want a dead car in Scotland and angry missus Moog.

 

Way back from Scotland stuck at 65 which improved mpg no end. Did sums and that took it back up to mid 30s. It seems that75-80 is start of boost and fuel nom nom

 

Currently got a blend of about 80/20 veg/diesel in it.

 

Not end of the world and hopefully something simple.

[Lacquer Peel]

You're all over-thinking.

 

It's quite cold just now, and if I remember correctly chompy fitted a fuel filter from a common rail BMW diesel which probably won't tolerate much thick fuel.

They can sound like a bag of nails and run like crap with simple fuel starvation alone.

[The Moog]

 

 

Some questions:

 

Was it a partial engine seizure or was it more fuel related do you think?

 

- just stalled at about 10mph. At time just assumed it was fuel and then it caught again.

 

Is there still plenty of compression when you turn it over?

 

-seems okish. If it was petrol I would say it is running on 3 with the symptoms.

 

Does it run better when revved hard, or whilst idling?

 

- better being revved although accompanied by black smoke

Is there any oil leaks?

 

What is the oil level like?

 

-need to check

 

Does the oil smell okay, or does it smell burnt?

 

- again will need to check

 

Does the black smoke smell like fuel or oil smoke?

 

- more oil I think.

 

Does the fuel grenade feel spongey? If you squeeze it really hard with the engine off you can find fuel leaks in the engine bay by listening for escaping fuel.

 

- nope it is pretty hard.

 

Is there a slight rattle from the crank pulley when you turn it off? It may be a loose crank bolt, causing the woodruff key to wear the slot bigger in the pulley and put the engine slighly out of time.

 

-again will add to list to tomorrow

.

Answered a fair amount.

Fair point. Will petrol thin it best?

[Lacquer Peel]

Petrol's great for thinning veg, my Caddy's running 10% petrol 90% WVO just now with no problems, even below freezing.

[Inspector Morose]

Just listened to the video. That's advanced, that is. Veg won't be helping, needs a thinner mix. Black smoke won't be oil, it's over fuelling (judging by chompys adjustments, quite a bit too.) put lots of (thick) fuel with a Bosch and you get that sound. (Oh, by the way, if there's metal filings in the pump then it's eating itself)

Worst case another pump. No real biggie. Up your diesel for a bit and report back.

[explosive-cabbage]

It does sound a little advanced/knocky in the video.

I warmed Graham about that filter setup, I would get it changed back if you can, the engine needs a fuel preheater in cold weather! If you need a replacement standard filter head give me a shout.

[The Moog]

 

I think points go to LP as it looks like it is fuel related. Today it started straight up without a clatter (except the usual dulcet tones of an XUD in full chug) 

 

Chucked £5 of petrol in and did the 8 miles to work with no bother. 

 

Having a quick look through the Chompys old thread & LP suggested a heated one.

Would that be an improvement over standard?  I used to hate chasing air leaks on the plastic ones. 

 

[Inspector Morose]

Yes. Out of interest, where can you find those? The BX doesn't run a heated filter and sounds like that when cold on higher veg. Solution is not to run on veg as diesel is just as cheap nowadays(no ready supply of clean WVO).

 

Oh yes, running silly levels of advance allows you to overfuel a bit more but over time will knock the little ends out. Leyland Nasties used to run obscene anoints of pump advance and would constantly run little ends in as little as 120000 miles. Leyland 680s with a F&M pump (later ones including the L11) ran lots of advance too and would run their ends far quicker than CAV pumped ones running a bit "softer". Running advanced is okay but you have to realise the whole balancing act of engines. (Get more power out one end - shorten life of component other end)

I'm just glad I don't have to work on that shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty, shitty engine anymore.

[The Moog]

Strangely since the noise has gone the mpg has improved.

 

Looks on target to get 500 miles out of the tank.

[The Moog]

Collected a new lot of veg nom non this morning from Señor Cabbage.

 

Filled up car and then lobbed the usual 10% pez in. Everything seemed fine till I had a FTP on way back from hospital.

 

Managed to coax it home. Checked the pipe and lots of air bubbles combined with the hand grenade being flat means something is afoot.

 

Undid this

 

To find this

 

Cleaned up

 

And everything is back to normal. Took the opportunity to alter the fuel screw a couple of turns to see if it can help MPGee.

 

Now stink of chips and petrol...

[beko1987]

Wow, what filter is that? May have to have a nosey at mine after 280k...

 

Bet there was a transformation when back together!

[Lacquer Peel]

Was that the problem all along?

[vulgalour]

Wow, that filter was grim.  Didn't look like that when Chompy last pulled it out though he did notice there was more crud in the bottom than there should be.  Probably stuff in the bottom of the tank but at least you know how to sort it in the future now.

[The Moog]

Tank filter. Top tip is to wait until it is nearly empty before doing it.

 

I would imagine that was the issue before.

 

Hoping it is just an accumulation over time. When I do a couple more tanks I might take it off for another look (when it is emptyish!)

[vulgalour]

yeah, he did look at dropping the tank to swill it out but given how much work that is on the Xantia - like every other job - he decided against it.  Hopefully this sorts your present running issues.  With the benefit of hindsight, the symptoms of bubbles in the fuel and the bulb being hard it is just what Chompy was getting before cleaning the tank filter so I guess it's one to be aware of.

[The Moog]

After the state of the in tank strainer, I thought I would fit an extra filter and change the BMW one that is already fitted.

 

I didn't have the correct fuel clips (will be changed tomorrow)

 

Will do another 1000 miles then change filter and perhaps just go back to one

 

 

Took opportunity to whip out in tank strainer again after 800 miles

 

Looks pretty clean in there.

[The Moog]

And today the xantia has rewarded me with electrical issues

 

If I turn the headlights on, the rear foglight illuminates on the dash.

 

After checking it looks like the tailgate lights aren't working, unless the boot is opened. Which points to gremlins in the wiring that goes through the boot aperture.

 

I hate electrical issues. And now it is pissing down again.

[binhoker668]

Yes, I'm pretty gloomy about mine too right now.  Need to magic up some cash first... Always the way.  Have you noticed that they never go wrong when you're moneyed up and ready to deal with it?

[binhoker668]

If we both lived nearby, these issues would at least give rise to some good craic!

[binhoker668]

Think i need to check which autoshiters live 'nearby' next time and purchase accordingly.  Weekends will then become fun and problematic.

[The Moog]

If we both lived nearby, these issues would at least give rise to some good craic!

They more likely would sync and take turns in breaking!

 

I have booked an auto sparky to fix mine and also do the relay mod whilst he is here.

CHEAT (jealous)

[vulgalour]

I bet it's one of two things.  It'll either be where the electrics pass into the tailgate and the wires have chafed or it'll be the towbar electrics have decided they don't want to behave properly.  Mike had a bit of a faff getting the lights to do what they should for the towbar when he installed it because of Citroen's unique approach to wiring and Haynes' unique approach to offering accurate, useful information..

[The Moog]

Cool will get him to have a look at that first. I think it is broken/chaffed wires as they are fine if you half open the boot.

 

He said he was going to check it all but quickest way is to replace the wires.
