Hello Everyone

im wondering if anyone might have a digital Workshop manual for a Nissan Navara D22 QD32 duel cab 4wd

Also couple questions about it

1: where the OBD port is located due to i can't find it anywhere

2: on cold start it blows excessive smoke, what can cause this

3: uses way to much fuel for a 4cyl engine and had fuel pump rebuilt properly

and 4: what can i use and run on this model from the other D22 model navaras


thanks everyone

there is no OBD port as they are not electronic.

how much fuel is it using per 100km open road driving?

what color smoke? typically for cold start smoke i would check glow plugs first.

 

[hellmatic]

hello and thanks mate for the reply

that makes it easy when comes to OBD lol

and not sure on the fuel consumption side

all i know to travel 116km it uses just over half a tank

and as far as i can remember the fuel oump
injectors and glow plugs all have been redone

 

[hellmatic]

and for smoke it's a huge puff of white i think then some what clears

116km to half a tank, thats dreadful.
start with the basics, compression test, valve clearances. air filters, fuel filters. is it sucking in air in the fuel lines.
then the harder stuff is checking injection pump timing is correct. also test how it runs with advanced timing or retarded timing.
otherwise its check the injectors and pump.
theres not much to them, enough compression, good spray pattern on the injectors and the right timing, and no restriction on the exhaust or intake.

ok ill start looking for new stuff again and make sure everything is new and running right, it does have a snorkle and its had everything rebuilt, but just wasnt sure what could cause it, ill also have a look at the timing, any specific idea what the QD32 engines timing is suppose to be exact, thanks jake

I always thought a puff of white smoke on start-up was likely steam and indicative of a knackered head gasket (or worse). Is it using coolant?

 

[hellmatic]

as much as i've checked and watched everything no oil or coolant used, that's why i have asked haha just to see if anyone has any ideas

any specific idea what the QD32 engines timing is suppose to be exact,

from the manual.
PLUNGER LIFT ADJUSTMENT
1. Loosen injection pump mounting nuts and mounting bracket
bolt.
2. Remove plug bolt from distributor head and install dial gauge.
3. Plunger lift measurement and adjustment
(1) Turn crankshaft counterclockwise 20 to 25 degrees from No. 1
piston at TDC.
(2) Find dial gauge’s needle rest position at step (1) set position,
then set the gauge to zero.
(3) Turn crankshaft clockwise until No. 1 piston is set at TDC.
(4) Read dial gauge indication.
QD32:
0.42±0.02 mm (0.0165±0.0008 in)
TD27:
For Australia
0.71±0.02 mm (0.0280±0.0008 in)
For Hong Kong
0.51±0.02 mm (0.0201±0.0008 in)
Except for the above
0.65±0.02 mm (0.0256±0.0008 in)
(5) If it is not within the above range, turn pump body until it comes
within standard range.
a. If indication is smaller than the specified value, turn pump
body counterclockwise.
b. If indication is larger than the specified value, turn pump
body clockwise.
4. Tighten injection pump securely.
Injection pump fixing bolt:
: 20 - 25 N×m (2.0 - 2.5 kg-m, 14 - 18 ft-lb)
Injection pump to mounting bracket:
: 30 - 41 N×m (3.1 - 4.2 kg-m, 22 - 30 ft-lb)

however some people just do it by ear if they know the right sound.

Steam will dissipate almost instantly, you pretty well have to be watching the tailpipe to see it. Smoke will waft away in a cloud/patch and be seen in the air for longer.
