Hmmh - a double post - NOW EDITED!!!
Has anyone on here delved into engine modifications on here?
Also whilst the head is off I will have a look for the missing tip off the glow plug
Made my brother feel really guilty for the blow-up so I get to borrow his mint Starlet Glanza V-Turbo (which is for sale coincidently) whilst I'm working on the Bongo

The missing plug tip (I'm guessing you used cheapo Chinese copies) will be lodged in the pre-combustion chamber - it's too big (I hope

) to go past the flame hole into the cylinder.

I am reading with interest as I appear to be having similar difficulties. Engine cuts out only after long run. I can get into town and drive around smallish journeys ok but after 20 min run on the motorway the engine will cut out and and keep doing so every time I slow down, until the next day when it has had a rest and for short trips will be ok again. When being followed I was told that smoke came out just before engine cut out/ stalled. Also as long as I don't have to slow down to much I can go for miles on the motorway and it hasn't cut out when speeding up, only slowing down. It appeared to cure itself for 6 mths (owned for nearly a year) but has recently started again. Not always spluttering though just 'dies'
Looking forward to a mobile summer traveling more than 5 miles from home!!

That doesn't sound like the same thing at all as this situation won't let you get up to speed in the first place.
Yours sounds much more like a blocked breather in the fuel tank so you are getting a vacuum. While you keep the speed up the pump can suck harder than the vacuum in the tank but when you slow down the tank wins.
Be careful - I've seen a tank that imploded when the vacuum got too much for it.
Try loosening the cap a little to allow air to bleed past it - if that helps you've found the problem.

Seem to remember a leaky fuel pick up pipe in the fuel tank giving similar symptoms.
You can't polish a turd - but you can roll it in glitter.

Thanks for that, I'm just re-reading and youre right they're not the same.
Will give it a go with cap and go from there.

Sounds like the inlet manifold is gunged up....

rustyp wrote:Hello there, I have an annoying problem with my Bongo which has been fine until now. It is a 2.5 TD.
When it gets up to working temperature and particularly in traffic the idle would go a bit lumpy then it would stall unless throttle applied, often I would have to put it in neutral and rev it at which point there is lots of smoke as it is over-fuelling massively. Eventually it would cut-out. After a while it would run for a bit when re-started then do it all over again.
New glow plugs helped a little but broke down
So....
Took it to my mates garage, diagnosed that the temp sensor under the inlet manifold was knackered so was changed (as well as coolant, oil and filter, fuel filter as it was due a service) and it ran like a dream yesterday and today until this evening when once it warmed up and was going up a long hill it wouldn't rev over 2000rpm, it would just stutter and die, below this was OK but after a while it just cut out altogether smoking like mad and stuttering.
Any pointers?
Cheers Russ
