I thought it was up to the driver, as there is an on/off switch, but am not certain.rustyp wrote:Will update my profile - I live in Saltash near Plymouth.

Is the exhaust valve supposed to move back out of the way automatically or is it down to the driver to switch it off?

Could be the banjo filter in your case then, if that doesn't cure it then try another new filter.rustyp wrote:Will update my profile - I live in Saltash near Plymouth.

) so I suspect the valve is overridden by the coolant temp. 
Hi Scanner,scanner wrote:Those are the classic symtoms of a blocked fuel filter - I know because I suffered them last night and had to change the filter - did so and cured them.
That is the main filter not the banjo BTW - I've suffered this 3 times now and never found cleaning the banjo on it's own does any good
Don't think that just 'cos it was changed recently it can't be the filter that's blocked - it can be, I've found it can block almost instantly.
Mine was perfectly OK Thursday - topped up with veg oil yesterday before a longish trip and it was chugging away last night.
Mine just doesn't seem to like a big dose of veg oil for some reason.
But check if you have the valve in the exhaust because if that sticks shut it could have similar effects.

Hi Scanner,
Looks like you need to get the Steam Jenny out.
No Air Flow Meter on a Bongo - at least not on a pre '99 model - later ones fly by wireRoberus wrote:Sounds like the same symptoms I had with my Subaru Legacy and a 205GTi....both turned out to be the Air Flow Metre....may be worth checking. They can be cleaned and refitted I think but usually once they start playing up best to get a new one.

Didn't know that Dandy....I just assumed they were vacuum pipes. I suppose if you choose to remove the valve you just join the pipes ??dandywarhol wrote:The valve in the exhaust has coolant hoses in it's circuit (wonder if flippa is aware of these
Have a look in below rusty - its ovvious if you have one - it's a box on the front pipe

- losing the plot again - I remember someone asked me about what to do wit hthe coolant piupes if they removed the exhaust unit - I asumed they were for coolant but looking at your post and Lushprojects excellent pages http://www.lushprojects.com/bongoparts/ ... esel).html they are just vacuum pipes.
Same here... I can just about get away with 40% on a really warm day, any more, and i suffer the same symptoms as yourself...scanner wrote: Mine just doesn't seem to like a big dose of veg oil for some reason.
rustyp wrote:UPDATE:
I checked the exhaust valve and all fine and dandy, as new.
Changed the fuel filter again and it seems that the bio-fuel absorbs water and turns it into jelly. Also it seems that the vegi oil seperates out in the tank and goes to the bottom because even though I am running a 75% diesel mix it was only vegi in the filter. Banjo filter also seemed a bit gooed up so cleaned it out.
Started up perfectly and had it ticking over for not long at all when I noticed water dripping from the head gasket
I'm not happy - will persevere
