Lumpy !!!!

[the guvnor]

hi guys

Well now the colder weather is upon us my bongo is running crap at start up

All is well after 5 mins but as she starts she is VERY lumpy for a few mins and lets out some white smoke.

Any ideas or should i not worry about it ?

Cheers

initial diagnosis with your symptoms being lumpy on cold starts....... sounds to me like Glow plug or plugs not working..... now if your a Veg user....could be the percentage Diesel/Veg needs adjusting....

If you like me and suspect say a glow plug....change the lot....that's what I do with anything on the Bongo....at least it is preventative maintenance not reactive, which is what the Japs do....... For example if a bush is worn on the roll bar.....change all the components....that kind of thing, so for me if a glow plug fails....I change 'em all..... a) they are all the same age & b) you know when they were changed and what parts you used.....

Sounds like glow plug/plugs.

Could be worn injector(s) causing poor atomisation.

Glow plugs and white smoke is just condensation.

Have exactly the same problem, lumpy with white smoke for the first 5 mins, but I fitted all new glow plugs 3 months ago!
Is it possible that it could be a fuel supply problem? Could it be the fuel pump injector 'O' ring seals? Just put my hand underneath the fuel pump and there is a slight leak, so air being sucked in could be the cause. Does your fuel injector pump also have a slight leak?

Check the earth on the glow plug relay which is under the bonnet, top left corner under a plastic cover.

Thanks for the comments guys. Yea, my thoughts were glow plugs also but i will check the earth first(thanks for that) as for a leak on fuel pump, nope mine is fine.

So, plugs first then hope all is well ! If not injectors should be next stop !!

Thanks again
