Smoking Bongo 2.5 diesel 1997

[Ryan S]

Hello all I am really hoping someone can help me, my Bongo is smoking on everystart up, smoke appears for roughly 2 minutes then disappears, after lots of intense reading I have replaced glow plugs and glow plug relay, I have also chucked in some injector cleaner with no joy, I have had the fuel pump timing checked also which seems to be fine, I believe this is fuel related, I am not a mechanic but have learnt a lot since owning this vehicle any tips or advice would be much appreciated, I have been told by a mechanic that it is likely injectors, as these are pricey I would like to check any other possible causes first.
Thanks!

Whiteish greyish smoke? Air in fuel? Front diesel pump seal? Allan.

Indeed it’s white/greyish, is there anyway test that can be done to check the seal externally? Or if I remove the pump is it a painful job? I have plenty of patience for such a task but I don’t want too push my luck too much with it. Unfortunately it is not allowing me to upload a photo. Thankyou for replying

on start up only then clears is a clue to it being the cold start solenoids.
does it only happen during a cold start and ok on start up when warm.
the 2 cold starts operate as follows. AIRCON OFF, THIS IS IMPORTANT. the first one kicks in if the coolant is below 10deg c then turns off at 10degc, then the second one kicks in from 10 deg to about 50deg c then turns off, when its deemed to be warmed up.

Hmmm. My cold start solenoid doesnt work but i have no starting issues.

To the OP- just to be clear, this is smoke and no steam involved. Your coolant level is not dropping?

[Ryan S]

Thankyou I will have a good read this evening , I have no coolant loss, definitely smoke, I am going to investigate the pump seals this weekend and get them changed, as now I know where the pump is I believe I had seen some sort of fluid on engine block which is now making me hope it is the pump seals. I will update as I go along with this investigation.

You can get a full set of pump seals, gaskets etc from the Bongoland Shop, see https://bongoland.co.uk/product/diesel-pump-repair-kit/

Just out of interest does that kit apply to a facelift 1999 bongo?

[Ian]

No, it's for early series 1 & 2 Bongos only.

[sotal]

Is there a kit for the facelift bongo?

[Ian]

I've not tracked one down. But that doesn't mean they are not available. If you have the Bosch number for the later edition pump I'll have another look.

Take care

[Ian]

I am, as the youth of today say, on the case.

[Ian]

Sorry, can not locate kits for later Bongos

Cold start/glow plugs working correctly?
