Anyone have a photo of a TD27t injector pump showing the screw to adjust fuel mixture? (Not Eti)

Put new injectors, filters etc in the Mistral but it still puffs white smoke on startup and when I boot it...guy who rebuilt the injectors reckons it may be overfuelling a bit, and to adjust the screw half a turn and try it...problem is I can't find the damned screw to adjust.

Its extra gutless too, which he says is another sign...so I'm more than willing to try it. Nothing ventured, nothing gained. Pisses me off as every other Mistral I see does not puff a thing!!

Any photos/drawings appreciated, cheers

White smoke is water in fuel or oil.

Black smoke is rich mixture.

also, the 19th post on this thread is an image, also by Crash.

its not a fueling issue as such.

its either a turbo issue, oil is leaking into the exhaust and possible seizing turbo.
or injection timing is way out. possible fuel line restriction (gauze filter in the pump ?), air being sucked in or worn out injection pump. other possibility is the basic pump timing is not correct ie chain out a tooth or pump being removed/replaced and not tuned back in.

Thanks guys..sounds like a bloody mission.

Don't have anyone here in Levin that is a diesel specialist as such, if I take it to a normal garage I'll pay more than the truck is worth.

Haven't looked at the gauze, the last fuel filter was on since 70,000kms (now done 150) and it was spotless inside when I replaced it...so unsure if water is in the diesel.

It uses neither oil nor water, starts easy and runs well but seems incredibly gutless, haven't got another Mistral to compare it to.

Cheers guys

well over due for fuel filter change.
that would be the first thing to change.

yep changed fuel filter, oil and filter, coolant...to me the "smoke" is a bit of a haze, smells reallly strongly of diesel

yeah that smacks of timing issues. fuels not burning and going down the exhaust. fuel in the exhaust will make white smoke.

so was it gutless prior to doing the injectors? or were you trying to solve the gutless problem by doing the injectors?

leaking injectors make it smoke too. hell what doesnt make them smoke.

Pm me and bring it around on weekend. I have a td27-t sitting here we can compare it to and have a tinker.

For giggles, check the mass airflow sensor wire is clean too. Improved my gutless old Mistral no end.
