I need help please, TD42 blowing white smoke

Hi my guess is timing i had the crank pully nut come loose and allowed the key driving the timing etc to wear enough to allow about 1mm slop in the key and you coulden't see the can for smoke( all white) mechanic said it was injecting too late to get a good burn
Cheers Kev

Check the fuel lift and pressure systems for the entry of air and bleed it carefully to eliminate any bubbles or pockets of air.
White smoke is often indicative of low temperature fuel burn as a consequence of air entering the combustion chamber with the fuel or as a result of the HP pump not fully pressurising the fuel due to an air pocket in the pump.

Take your wagon to a mechanic.
All the best.

Wagon probably won't make the 650 klm trip as it is, would probably do more damage. I suspect it is a minor thing causing this problem, just not sure what it is, any suggestions appreciated, thanks guys,

Maybe it's like a white flag.
It's trying to tell you it's surrendering.

Pump timing is 180º out

Did your mate fix the pump in the vehicle or on the bench?

If he did it in the vehicle the problem is unlikely to be pump timing and more likely to be air in the fuel.

If he pulled the pump off the vehicle to fix it then the problem is most likely to be timing and to a lesser extent air.

I am guessing that to replace the solenoid he took the top casing off the pump. He should not have had to make any adjustments to the pump for that repair.

Assuming he has not made any adjustments I would guess that he has damaged the gasket/seal between the top casing and the pump body, and that it is leaking air and or fuel. I would replace that seal. It is a really difficult area to see, a decent size mirror can help.

The other possibility is that the linkage on, the top of the pump is leaking. Again they genrally leak fuel out rather than pull air in but it could be contributing to the problem. If that is the case you need to replace the top casing of the pump.

I would also get it to a diesel fuel injection specialist ASAP.

As others have said, if he did not take the pump off it is most likely air as it can take a while to bleed out of the system. Just give it a run for a while, and crack the injector lines at the injectors while running to help bleed the air out.

Thanks everyone for your input. My mate pulled the pump apart again and the round plate is 180 degrees out, making the internal pump timing 180 degrees off. He has lined up the pin on the plate with the keyway no the shaft and is putting it together, hopefully that is the end of the story and it will be all good again.
Thanks. Happy travels.

Im really concerned as to why the pump was removed to change the stop solenoid,it can be done without removing pump.

Hope you get it sorted!!!!!

I suggest he pulls the top off again and has another look at what he forgot to do....it definately has something to do with the top coming off the pump, might be spring tension or similar, best option if you cant fix it is a reco pump shipped in from cooma diesel (no affiliation, but they do do exchange units)

Thanks for the advice everyone, my mate is a mechanic with a little bit of diesel experience, but not much, asd we were in a shed at Julia Creek with basic tools.

He could not get the solenoid off without taking the back off, but perhaps there is a way he did not know about, anyway he got it sorted and we drove the wagon back to Townsville, but it is running a bit rough and I suspect the fuel filter may be blocked, or leaking, the vehicle sat for some time before we drove it so tank is probably a bit rusty and diesel a bit tainted.

We put a new filter on it before the trip, but it is playing up a bit now, but at least I am in the big city and can get the vehicle to a proper workshop.

Thanks for the advice, it might help out someone else one day as well.
