I bought a 03 GXL cruiser 3 1/2 years ago with 70000 kms, it was a MUM bus, I have serviced it every 5000 ks since without fail, it now has 160000ks on the clock.


3 years ago on Frazer Island I let it idle for 2 hours to charge a battery and keep the fridge cold until we gave it a good run the next day, once the battery had charged I gave it some revs and it ran like a charf cutter for about 5 minutes, then it ran fine up until this afternoon.

I did a service on it today, it was close to 5000 ks over but it had not worked hard in that time, it is the first time since I have owned it that the service was late.

I drained the oil replaced the filter, I used the same oil I have used since I bought it, I ran it for a few minutes and then throttled up to see if the oil pressure would lift, as I did so it ran like and old mole and blew heaps of blue smoke, I turned it off then started the process again, this time it had less smoke but still ran like a pig, I repeated the process a few more times, the smoke has now gone but as I throttle up the oil pressure drops and it runs like a pig at mid range revs.

Has anyone come across this before?? has the engine been glazed from the previous owner?? I am stuffed if I know and I have owned a few 1hzj engine in my time.

Thanks in advance.

Doesnt sound good, remember its not just how many k's you do, but how you do them and how old the oil is. 6 months is long enough for 1hz's to be using the same oil.

Although blue smoke is a fue/air problem usually. Black smoke is generally an oil problem. Probable a million things you could try, but if its only done it since you chagne the oil, then i'd say thats were the problem lies.

Blue smoke is usually Engine Oil burning, Black smoke is usually over fueling. White smoke is unburned diesel

White smoke is usually unburnt diesel from running too cold combustion temps.
Black is unburnt fuel from poor injectors, overfuel/under oxygen (typically also a sign of a turbo failure or blocked air filter).

Blue definitely engine oil burning.

Almost, just backing up what you said, but not many people realize that the white smoke is usually from running too cold.

and just added a bit more info.

3GoBush,

no mechanic here, and probably a silly question:

did you make sure not to over fill with oil?

I just thought if the oil level is way high in the sump, then the crankshaft action would splash it around like mad, create lots of bubbles which then makes the oil pressure drop as the oil pump won't work well with all the trapped air in the liquid.

Best of luck, Peter

At 150k, the timing belts need to be replaced. Have no idea if this could cause the issues that you raise, but just maybe the timing is a little out.

This may be totally irrelevant but anyhow several years ago I was called to tow a cruiser that the owner had just changed the oil in.

His problem was that he did it when the motor was cold and poured the oil in too quickly.

The result was that the rocker cover filled then oil ran down a (pvc??) pipe into the inlet manifold.

When he started the motor it got a bellyfull of oil where oil is not meant to be!

The hydraulic action bent a rod or two.

Maybe you had something similar but not quite so extreme?

Cheers Neil

was that a 60 series? I know it was a common issue with 2h motors (did it myself) no reason it couldnt happen with a 1hz but I fill up a bit slower these days

When you take it to a Toyota dealership (work shop) or a diesel mechanic (expert) don't forget to post the result.

I would suggest the 2 hours idling on Frazer Island may have glazed the cylinder bores and now the oil control rings can't perform their function.
You could try a couple of teaspoons of a MILD (Bon Ami) abrasive down the intake manifold for a short term fix (very short) or have the engine dismantled, the bores honed and probably new piston rings.
No engine, but especially diesels like idling with no load for extended periods.

Hi ob

I have run it this morning for 150 ks and it has settled down, I is just blowing black smoke today, the oil pressure seem to have settled as well when it cools down I will check the wire going to the pressure switch.

It still runs a bit rugged at mid revs but I have taken it to a mechanic mate of mine, he seem to think that it is not pulsing properly at #4 cylinder, it is going to Darwin tomorrow and being put on a dyno.

I will report the findings of that test.

The QLD police used 100 series cruiser s/wgns for roadside speed camera's until recently.
They used to spend entire shifts with the motor idle-ing to run aircon's while the officer sat in there.
While it's not real good for engine longevity, it didn't seem to worry them while they had them for 3-4 years that kept the cruisers for.
I very much doubt running the motor for 2 hours once some time back is the cause of the problem.

Shane

you remember Brad from the Gathering we went to at washpool?

well his 100 series was blowing heaps of black smoke and running rough and he took it to some guy in Lismore i think who diagnosed that the piston in the fuel pump was so worn out that its a wonder it worked at all.a few grand later with new piston and rings in the fuel pump it was sorted.

his 100 series.........an ex camera car used by the police(sat idling all day)

I remember talking to Brad about that, he didn't find out till later about it being ex speed camera car.
I fully agree that idle-ing day in day out is no good for em, but a once off 2 hour battery charge up a coupla years ago, is not gunna cause problems in my opinion.

I just got home from Darwin, I handed the car over to Premier fuel injection and these guys sorted it out.

All it was, was a dose of bad fuel.

They fixed that and tuned it on the dyno, I now have an extra 8 kws of power from a 1hz, all up to the wheels is 49.9 kws. LOL

The fuel I got was from Cooinda.

I drove home a very relieved man.
