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

I have a 2005 Ford F350 diesel with 6.0 powerstroke I have been having problems with a misfire I believe it is fuel injectors. Due to water in the fuel system. i started using diesel clean fuel injector...

Diesel clean will help, but it won't remove all the water in your fuel. Try some water dispersant fuel treatment as well.

I'm guessing your water in fuel light came on? It this happened for any length of time, your fuel water seperator sensor could of shorted out, this will cause a misfire, and will have to be replaced. There are several other things with the 6.0 that could be the problem, but i would start with this first. The back pressure control valve sticking and the pressure sensor out of calibration are also common problems on this engine.

Good luck, i hope this helps.
