1HDT SMOKE/FUMES AT IDLE (1 Viewer)

[jayden spencer]

Hey guys i have an 80 series with a 1dht, and at idle it produces a very fumy smell and a noticeable amount of grey smoke.
I have replaced the injectors, and it has had a brand-new complete head fitted with new valves etc but the issue still persists.

More information would help.

Also, do some searching in the diesel tech section of the forum. There's a lot of good info on these engines there

Is Moura in Queensland? Or Spain.

When you say fumey, does it smell strongly of raw diesel? Or smell like burnt oil?

If it smells like raw diesel, your injection timing may be retarded.
When was injection timing last checked?

Is the injection pump original? Or had any work done to it?
How many Km has the engine & injection pump done?
Has the engine been tuned up by anyone?
Does it have fresh air and fuel filters?
You can play with fuel settings yourself if you're game. There's a detailed thread on this in the diesel tech section.
