Here's an interesting little problem.

Early last week drove the truck to work (1HZ), ran perfectly. Jumped in to drive home, it wouldn't rev over 1500 rmp and blew white smoke from 1400 rpm. I linped to my mechanics shop and he suggested replacing the fuel filter. Did that and truck ran perfectly again, phew, problem solved (though I'd changed the filter only a few weeks before).

Jumped in the next morning to drive to work, same problem again. Took other car to work.

Have tried the truck a few more times since and even driven it a bit without issue. I've checked all the fuel lines and the inlet to the fuel pump, no probs there.

White smoke is excesive fuel, could it be the fuel pump or an injector or two?

What's your thoughts?

I thought white smoke was oil and black/grey smoke was excessive fuel?
I had troubles with my old 1hz cruiser and it wasn't running right because the old rubber o-rings in the injector pump had started to weep out fuel and suck in air etc which made it work fine sometimes and the next day run like shite could be something similar if you've got an old pre 94?? 1hz because they apparently had basic rubber rings in the pumps that hate the new low sulphur fuel.

Blue smoke is engine oil, white smoke is undurnt fuel, black smoke is over fueling (running rich).

Fuel pumps been rebuilt with vitron seals.

Pete, this will sound a silly question but did you last fill away from Canberra on a trip. I have had similar problem but only when temperature is cold. Ie filled up on central coast and came back to this area. Very cold overnight and couldnt get car to rev until fuel warmed up (not vehicle warmed up). Mostly an issue in the cold part of winter but we did get down to 3 deg during the week. Canberra uses a winter blend of diesel, and when you head further down to Jindy they use alpine blend. The cold overnight temperature sends the diesel waxy and thickens giving fuel trouble. Struck this twice over the last couple of years after trips and now always fill up on return and I dont wait till the next day. Sounds stupid but with work we get all diesel vehicles to fill up upon arrival with local fuel.

How to fix is add kero to tank and then fill up with local blend. Last year had a real bad dose in middle of winter and had to change fuel filter as well.

I only use bio that I make. Thus I know the quality of the fuel every time I fill it up.

The issue has surfaced only once since the initial event. It does however blow white cmoke at start up nearly every time now. My diagnosis is a leaking injector after shut down.

Yes Blue smoke is bunt oil, Black smoke is over fueling (unburnt fuel). White smoke can be burning coolant it can also be caused by underfueling.

I had a troopy and once up the top end similar thing happened, injector pump was breathing air after i turned the car off and next day would take ages to start until it bled out and heaps of white smoke. Had rings in pump changed and ran/started sweet after that.

I get white smoke and poor economy when I drive my HDJ80 hard.. I'm assuming its unburnt fuel.

what can I do to fix/adjust this? Thanks.

IronPaw, get the pump and injectors overhauled.

Both times my issue has happened the nose of the vehicle was pointing down hill, most of the time when I don't have issues the nose is level or pointing up hill.

Any more thoughts? I'm still thinking injuctor.

Something in the tank covering the suction causing fuel starvation, lean burn and white smoke.

That is another thought I have had, but it happens on both tanks.

Is it possible fuel is leaking out of the front shaft seal on the injector pump and dribbling into the crankcase? I know you had the pump rebuilt but I have seen premature failure of the seal especially if the front timing housing has been removed at some stage.When reassembling the housing you need the pump in place to align everything as there are no dowels IIRC.

Oil level has not changed and it doesn't burn oil so I'd suggest not.
