Excessive Smoke

[Rocky_K]

Hi all
I have a Landcruiser Prado 120.
1kd 3000cc diesel turbo.

Recently changed the pump (second hand) and brand new injectors. All pressure tests are good. The power is brilliant.

But on starting there is a lot of grey/blue smoke. Then on reverse there is still the same smoke...on going forward it turns to normal black diesel smoke.

This image below is on start

Any ideas what is happening?

Thanks in advance

Was the fuel pump and injectors changed to try and cure the smoke or has it only started after those jobs?

Blocked crank breather ?

Turbo oil seal ?

It's started after I changed the parts

Plus the block smoke.puff is very heavy on 1st and second gear...around 1500 rpm

About 1500 your turbo kicks in altering the fuel/air ratio , maybe the ecu is not sensing your off boost ?

Cost nothing to pull and clean sensors .

I can try look into these

The car went for service... injectors were not behaving too well only to find out the previous owner had put three 2kd injectors instead of 1kd. The pump had a chink that was repaired and the pressure test was showing its not working properly. So decided to change them both.
