SOURCE: oil mixing with Diesel and car emits white smoke.

The copper washers on the bottom of the injectors can give this fault if they are not renewed when the injectors are replaced .

If you have changed these allready and made sure you pulled them down exactly as the manual says in 3 stages then you may have a bad injector - see your Isuzu dealer .

White smoke is usually a sign of coolant burning. Carefully open the coolant cap, sniff the inside. If there is an exhaust smell you more than likely have head gasket problems. A further diagnosis is needed to be sure. Also ensure that any wires/plugs are reconnected. If the oil sensor is unplugged the vehicle wont start.

SOURCE: My Isuzu Bighorn 4JX1 RJM Engine stalled after

the engine oil pumps are in the rear of the engine(trans out) and behind flexplate /flywheel, were any of these 2 engine oil pumps touched if so the flywheel /flexplate has to be timed to crankshaft position, so you might have it in the wrong position, if your talking about the diesel lift pump (injector pump) that also supplies high pressure engine oil to injectors, after replacing this there is a learn procedure for the rail pressure control valve that is on pump. this can only be done by dealer or some one with Tech2 scanner tool.

If oil mixes in the combustion chamber, then you're up for an engine overhaul. Nozzle changes won't do.

SOURCE: i cannot start my isuzu bighorn w/4jx1 engine. we already changed the turbo but still it emits too much smoke in the exhaust and after a while the engine goes wild and we cannot turn it off in the ign

Its a diesel and its running away so do not try to start till you do the following and yes i know i will be amolished for being a cowboy by the other experts but what you do is to make a gasket for the EGR valve from a coca cola can and seal it off if you dont it may run away and blow itself to pieces .If you do this then it run as normal as the older trucks never had these thing fitted and they all run ok in my day ,exactly whats wron i couldnt tell you without my head under the bonnet but do as i say and it run perfectly

How to fix an injector pump of 4jx1 engine


this is a USA forum what country are you in?
Fuel systems vary by engine, and country, so......?????
what needs fix'n?

the word fix has many meanings
  • how to rebuild the pump?
  • time it?
  • how to remove it put back?
  • how to bleed it.
  • and on and on... or a lift pump or ?
try to say what you are doing "the job" and why,
or if not a job, must be diagnosing it, ?
say , im trying to test it or. what ever you doing.
we cant guess, what fix means.
Diagnosing direct injection?



The 4JX1 is a 3.0 L direct injection diesel engine, turbo, some intercooled, which replaced the 4JG2 in the Isuzu Bighorn/Trooper/Holden Jackaroo.
It uses unit injectors and 4 valves per cylinder.

European and Asian buyers could opt for the diesel.

see we dont have this.
troopers are sold in Asia too, but not here with diesel.

Why the diesel mixed in engine oil for isuzu bighorn 4jx1 ,how to fix?


lots of ways.
all bad.
someone poured it in is 1. (jiffyboobs?)
extreme engine flooding may be one way, on a very worn engine.
leaking past very bad piston rings.
or the induction filled up with Diesel and backed up to some vent to crankcase, (PCV system, breach)
or far worse , cracks where cracks dont belong.

I cant find the location of diagnostic socket of Isuzu 4jx1


The ODB socket is just under the plastic trim that goes over the gearlever cover by your right foot , no tools needed to get it out .
The 4JX1 is a HUEI type engine so the diesel is not under high pressure until injected .
To prove if the fuel is starved put fuel in a can and pipe it into the hand primer pump direct .
Most likely cause is the Rail Oil Presure Sensor as this controls the amount of fuel injected via the ECU .
