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.

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

Isuzu 4jx1 mixing diesel in water. what is cause. and how to remedie


Where are you finding this? Diesel and water would normally only mix if water was getting into the fuel tank. Are you sure it is diesel? If you are finding it in the coolant reservoir it is more likely to be engine oil. This usually suggests a blown head gasket.

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.

wow first post ever posting country ,what a brave person. !!!!
welcome to USA forums ,that have no such car.(truck)
the line up. (wiki list) so its 3.0L 4JX1
stalls and lost power.
The 4JX1 is a 3.0L 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.

can be caused by many reasons. get it scanned yet. ?
or see FSM book on flash codes from the direct injection fuel
controller? (per this engine option and market)

does turbo have proper boost? (PSI boost or +1 bar boost?)
does it even have a boost gauge.?
there are over 50 causes, of stalls (most inside engine)
but its not getting boost or the injection rates are wrong.
there are basic tests for each covered in the FSM
Factory (oem) service manual, with coverage for this engine.
