Hunting, whiteish smoke on idle, diesel knock..

[Bananalad]

Wild guess and say my pump is too far advanced??

If this is the case why has it gotten worse over the last few weeks? The pump was adjusted so it was running well when put on so why has it changed now? I cant think of anything that was changed to affect it really.. Thanks

Does it do it when its warm /cold/on start up?

[Bananalad]

Used to be when cold and on start up now its doing it when its warm.. Any ideas? Someone else said injectors

[KrisB]

Dirty injectors most likely mate.

[puglove]

had this ish on one of my old Dts and could never find the fault, on cold start it you could leave it on idle for like 45mins and it just wouldnt clear untlll you drove it, tryed so many different things and i just couldnt solve it


This is my Old DT after running for about 30mins on a warm day after being sat for 8 hours, somthing like this?

[Bananalad]

Yeah thats exactly it puglove! Still reckon dirty injectors kris?

[karl1989]

id say injectors too. mabe clean the filter in the sender unit too.

[Bananalad]

Refurb the injectors or is injector cleaner run through the system any good? Thanks

[londondan86]

Yea you could try some redx or something. I tend to wait till the fuel light comes on then tip in the whole bottle then take it for a good thrashing. Or just chuck a litre of perv in to the tank!

[sweeney1987]

fill filter housing with kero, should cleam them out

Diesel purge is good stuff get about 4/5 litres take feed and return pipes into a 5L tub and run the car on it neat for a good 20/30 mins i did this and cleaned everything like a whistle and stopped this problem for me

Can get diesel purge off ebay but it is fair pricy but worked a treat for me

Other than that get another set of injectors or take them for refurb

[Bananalad]

5er of petrol put in with plenty of diesel in the tank, haven't got a chance to run it all through yet but the problem is after getting worse.. If i let the revs drop while driving the car cuts out.. Anyone any ideas? Or should i just get the injector done?

[306__xrdt]

Rocker cover gasket leak?

[Bananalad]

Dont think so.. Need this sorted for tomorrow ideally..

[Bananalad]

So many threads on the internet about this but no answers Air getting in somewhere?

[Tom]

Cleaned the injectors?

[Bananalad]

Going to take out the injectors tomorrow for a refurb, any last ideas?

[306__xrdt]

It could be air getting in to the dieselpump a small leak in the dieselpump.
Iff not it could also be the timing is wrong, didd you changed the glow plugs?
Always bay bosch glow plugs or ngk but bosch are preffered.
I hade some brake flued in the dieseltank and itt runs much better now, the problem is with diesel injector clean bottle it can dry out the injectors/dieselpump and then there is less friction in the camber, dieselpump.
What you can do is use diesel injector clean and after that trow in some 2 takts oil.
It should run smooth but hey best is off course clean the injectors while taking it out.
I have seen some treads how to clean injectors also on youtube a peugeot 306.
So good luck and have a nice day.
