2.4L (24Z) 5 spd (Project Log below) 17jan2008
Project Bush:: 1984 "Nissy" 720 4X4
VEHICLE HISTORY ::
Left for dead 2 yrs ago because ran on only 4 plugs, problem thought to be distributor pick-up.
p/o bought/installed 4 other j/y distributors thinking all j/y distributors prolly came from trucks
someone else didn't want to spend money on(new dist=$352), concluding the j/y distributors
must also be bad. Truck has 250K km's on it.
REQUIRED INFO ::
Clutch pedal switch when released causes a relay under dash to squeal-disconnected?
Gas tank leaking, could be from the way I mounted it, frame flex may have split it?
AQUIRED INFO ::
Haynes 1980-1987 Nissan repair manual
Engine Type: Nissan Z24 - Inline 4 cylinder 4 Stroke
Years - 1984 - 1986 / 146.8 c.i.d / 2.4 L / 2389 cc
Bore x Stroke: - 3.50 x 3.78 - Compression Ratio: - 8.3 : 1
Power - 103 hp @ 4800 RPM - Torque - 134 lbf·ft @ 2800 RPM
The firing order is 1-3-4-2. The rotor rotates counter clockwise
Q= what years/models share the same parts/engine etc.. Z24 motor?
A= '84 through '86 Z24 engines are basically the same. '86 was the last year for the Z24 and
first year for the 'new' Z24i with Throttle Body Injection. The Z24i will swap with the Z24
if the TBI is removed and the Z24 carb/manifold/distributor and drive spindle are used on it.
Pre '83 front suspension will not swap onto the '84 or newer trucks, nor will the front
brakes or rear differential. The '81 and on FW5W71B 5spd will switch (just check length) The
post '86 Hardbodys used the C type shifter with integral transfer case. The 2wd 5 spd might
work, don't know about length. If it's the same length it should work. The '84-'86 rear
differential carriers, (C-200) do not match the later '87 D21 Hardbody's H-233. The '83 and
'84 boxes and hoods are the same, but not the ones before or after. The '83 boxes may still
have a stamped Nissan tailgate,with a Datsun decal on them, the '84 was the first fully
The '83 through '86 dash is different from previous years and has round gauges
and optional clock and tach, very nice.
Cornering lamps, bumpers, front aprons, headlight cases and grilles are consistent
between the 1983-1986 models. Most other body parts (like fenders) are interchangeable
between any model year.(tyvm datzenmike)
- Check the first fuse at the far left hand side in the fuse box.
- One set of plugs (intake?) are powered directly through fusible link via ignition switch.
- The second set (exhaust?) are run through a 10 amp fuse.
- The ignition switch provides power to the ignition module in the start and run positions.
- If the switch or contacts are bad, during start up it fires and runs but when the switch
is released into the run position there is no power and it stalls?
- The timing is slightly advanced because of the shorter burn time with two plugs.
- set the valve lash and while valve cover is off check chain stretch
- set the idle and mixture, set timing, check all vacuum hoses
- inspect air filter, plugs, leads, cap/rotor and wires to both coils
- replace fuel filter, located at frame near right rear spring front shackle.
- there is a small fuel filter on banjo fitting at inlet pipe to carburetor.
- electric fuel pump has internal filter but do this one last only if necessary.

Replaced the original after the battery light started the on/off routine, then totally off.

Mount came loose on original rad, rad jumped up and the fan bit into the lower hose, killing the fan and rad instantly.
