The temp has now dropped where I am to about 5 degrees in the mornings and the van smokes like hell if started and left ticking over. If you drive off it clears straight away but will start again if stopped for too long when the engine is cold. Smoke is bluey white and doesn't smell of diesel ? Any clues, valves, valve seals or rings ? It's a bit embarrassing if someone is walking past at the time with their kids !

I'd deffo check the timing.  Mine was smokey when cold and needed the timing tweaking.
 
Having said that, it goes with the territory.  My experience is limited to my own JX - it'll start on the button every time but whether I get a bit of smoke depends on the weather.  If it's damp/cold then it'll cough and splutter a bit before settling into a rock solid idle. I consider it to be 'character' Wink

you said it didn't smell lie diesel though didn't you...

so is it burning oil then?  If it goes away when it warms up, then maybe you've got a leaky turbo?  My old turbo was completely bolloxed and I used to leave a nice smoke trail for the first 5 mins until it warmed up.  It would be worse after standing at idle for a bit too - big puff of bluey white smoke when you gave it bit of throttle.

It burns no noticeable amount of oil, less than a 4 year old golf. The turbo is new, before I replaced that it smoked in a big way, on hills you wouldn't want to be out in daylight ! I get the puff of bluey white smoke on initial start up then it smokes only if left ticking over. As soon as you pull away its fine. I had a fair bit of feedback a while ago when I posted the question and am aware the breather pipe from the rocker box cover can cause a little smoke. The reason I'm now looking again as it's much worse in the winter when it's cold. In the summer I convinced myself it was the norm for the JX, but now I'm convinced it isn't again.

If it's a problem when starting in cold conditions i.e. like it is here in chilly Caerphilly, then I imagine that it'll be glow plug probelm of some sort.
 
Started mine this morning to take it down to the bodyshop in Port Talbot and it coughed, spluttered and smoked like a mad thing.  Cleared almost immediately and settled into the usual rock solid idle tough.
 
It depends on where I park it though - you know how sometimes you have to scrape ice of your windscreen, but the car next to you doesn't 'cos it's in the lee of a building or something....?    It's a bit like that - usual place I park is still, no eind etc and gets really cold.  Cue spluttery start and a bit of smoke.  If I park on the other side, it doesn't happen.... I've given up trying to work it out...Tongue  
 
I'm guessing I could do with changing a plug or two, but I can't be arsed at the moment LOL

It starts instantly, if it was glow plugs it would smell of fuel wouldn't it? If they were easy to change I'd do it anyway but seems to be a bit of a pain in the arse from what I can tell.

Hi Zeb, 

Similar ‘cold weather’ start up smoking issue with my JX

It seems to me to be a seasonal temperature issue in my case. In the warmer months I just get a light puff of smoke from the motor at start up which quickly clears. But as soon as winter approaches & temperatures plummet to regular sub-zero degree morning temps {we live at 650m altitude in a mountainous region of southern France} I see the return of heavier smoke at start up which clears once on the move. The motor use’s little or no oil, is regularly serviced, has good compression, a new turbo & pulls strongly.

I suspect for me it could be a combination of worn valve seals & the use of Mobil1 5W-40 synthetic oil. I use Mobil1 to help cope with both the low winter temps & high summer temps, but I’m thinking the thinner oil properties may allow oil to drain down past worn valve seals which then burns off during start up. The think stone cold weather will highlight any ongoing motor issues such as iffy glow plugs, worn valve seals ect…ect.

 

I’m going to change the valve stem seals with head in situ during Spring 2009 & hopefully for me this will cure the smoking issue Smile. Just need to now locate the tools to carry out this task. I’ll also pull/inspect glow plugs & replace any iffy looking ones.

 

Cheers…………. La Brique

Bonjour La Brique

Sounds exactly the same, stem seals is the only thing I can think of. I assume it is only an elaborate pair of long nose pliers you need designed especially for the job, I was thinking of doing the same. I believe they are not engine specific and if I get my hands on some I'll let you know. Coincidently you are down the road from me (Or up ?) I'm in Toulouse and still looking for any T3 specialists. I always seem to need some part or another which I usually get from the UK. I would also like to find a reliable mechanic as I don't have as much time as I would like, particularly now as there is a healthy few feet of powder in the hills. I went to Baqueira-Beret last weekend and it was better than anywhere I went last year here or in the Alps.

Want to change 16 valve seals instead of 8 ?

Salut

Zeb

Bonjour Zeb

 

I’ve spent time flicking thru a Sealey catalogue & they list various valve stem seal pliers. Maybe other forum members who have done this job already can offer advise on the particular type of tool required i.e. straight, long or angled stem seal pliers. Sealey also list various head in situ valve spring compressors needed in order to allow replacement of stem seals. I’ll do some more research before making any purchase. No rush as I cant get the T3 in the basement as it is full of clobber, so it’ll be an outdoor job in warmer temps!  

 

 Toulouse, you’re located just over the hour from me. Do you work at AirBus? We are midway along the Aure Valley {D929} on route to the ski resort of St Lary-Soulan. Although close to the slopes not tried skiing to date, as more time is freed up I should try to find a local instructor & maybe give it a bash!

 

 As your self I get most of my T3 parts from the UK from stockists such as Brickwerks, Vw maindealers {UK & France}, JustKampers & GSF. Also parts from Germany {BusMan} via eBay. Not looked for a local mechanic as I have tried to carry out any jobs myself. No doubt there will be some tasks ahead which I might need to seek out professionals. I’ll keep you posted if I come across any T3 specialists or time served mechanic.

Hi La Brique,

Yes I am working for Airbus. I try to avoid main dealer as my last experience was quite a shock 200 euro's for auxilary coolant pump, 80 pounds from GSF both are Bosch. I only buy hardware type stuff or use them as a last resort. The thing that really surprises me that even service items here are so expensive from an average auto-parts shop it's cheaper to pay the shipping costs from the UK or Germany.

I guess you're also English, what brings you to France?

Let me know the story on the valve stem seals if you can remember.

Cheers

Brian

PS. Get on that mountain you'll enjoy it

Hi Brian

 

I prefer to buy genuine if the price is right or as a last resort if an item is unavailable elsewhere! In most cases as long as the item is manufactured by the o.e. supplier I’m happy. I will though be purchasing a dearer genuine radiator as I feel the quality is better & we need all the cooling we can get at times tackling some of the steep mountain gradients we have around us. After that maybe an oil cooler kit from Brickwerks to keep temps in check under heavy loadings.

 

I agree, auto-part shops here in France are very expensive. Saying that I purchase my Mobil1 from the better supermarkets here as it’s well cheap compared to UK prices. I think I paid abouT3 euros for 5lt’s.

 

Yep, I’m British.

Came here to get out of the rat race, after over 25 years of shift work had taken it’s toll we wanted a slower pace of life. We will return to the UK at some point as we feel its still home, I do miss a good pint of bitter & the British sense of humour LOL

 

I keep you updated on valve stem seal replacements.

 

Cheers………John
