    Timing can cause dieseling or after running . Smoke can be different things . Black smoke is rich , white can be water/coolant in exhaust and blue can be oil .

    I'm thinking leaking injectors or defective fuel regulator allowing higher fuel pressure can cause rich burning issues .

SOURCE: large amount of white smoke on first start of the day

Have you had the injector recall check carried out? There is a problem with these injectors and this produces the symptoms you are describing. I suggest that you contact Isuzu direct for help. They have been very helpful in the case of my trooper

SOURCE: engine suddenly started smoking through exhaust,

Unfortunately these engine have a problem with oil consumption. With design the oil rings on the pistons tend to stick due to carbon and such. This allows oil blow by thus burning the oil at a high rate. And most of the time you will not see it out the exhaust and the engine should run fine. I have had some luck with performing a top engine service. This is removing all the spark plugs and injecting top engine cleaner into the combustion chambers and allowing them to soak overnight, This has loosened them some for me. Other than that a complete overhaul would be ness to repair.

If you keep your oil level up you should not have any mechanical problems as a result of this. Isuzu states that 1 quart every 1,000 miles is normal.

Hope helped.

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 trooper 2003, skyroof version, 4jx engine. Diesel and oil mixing in engine. It might be the electronic fuel injector o ring. Need help badly. Isuzu alabang is giving me some pain. Big Black smoke...


If you are sure that the engine oil is coming into the combustion chamber, then you have to overhaul the engine. After the overhaul is done, have it calibrated and and clean the exhaust pipe to get rid of the black smoke. And! remember, for diesel engines a big black smoke will always come out the exhaust if you suddenly step on the gas too deep and then over-revving it. (I mean always, that's why roadside emissions people are so stupid when stepping on the gas, they always step on it suddenly and over-rev it, it's a sure fail)

Starts first time, no smoke on normal running, then rev up and white smoke comes out??? no wrong feul!!! changed air, oil and feul filters, but still throwing out white smoke on reving... can anyone help?...


It could be a coolant or transmission fluid leak in the combustion chamber. Check your coolant and transmission fluid to see if one or both are low. White smoke from the exhaust is a classic symptom of a blown head gasket, have your cooling system pressure checked. If that checks out good then have your transmission checked.

Engine runs wild with white smoke


If its a 4JX engine then its injectors and seals at fault dont run it any more cos it may blow up - like rods through the side !
The diesel is going straight into the engine without being injected and as the fuel lift pump is mechanical it wont stop on the key .
Should be under isuzu warranty though they are doin that repair on 1998 Troopers over here for free .
