Thread: Diesel engine problems

Not good news! Car was running alright, well, good enough. Was doing 10mins at a time with test runs without a problem, so we decided to take it for a trip out bush. We got about 25mins away and overheating, loss of power and dying when clutch pressed.

Had a bit of oil come out of the cap, and rocker cover. Let the car cool down for ten mins and we managed to limp it about another 5km to where I could park it. Began to really die, wouldn't rev past 2.5k rpm, when clutch pressed it began to rev up to 2.5k. So, I'm now in a position of do I cut my loses and move on, or try find a second hand donk to put in it. They are around $3k!

Open to a brain storming session. No bad ideas in brain storming,

Sounds like it was trying to run on its own juices again.
Look up "Cost Effective Maintence" from Qld.Their stuff is really good at cleaning out dirty jap diesels.It may beyond the point of no return,their stuff wont fix mechanical faults.

Can't help but feel it is beyond a 'liquid' fix. Ive spoken with Dave, I'll try getting the thermostat out, running proper coolant instead of the watered down nothingness that is in it, a few coolant flushes then see if the overheating stops. From there, there is still the fuelling issue.

Im not convinced of that, with high temps reported, the compression numbers I got off of it when we did the compression test and a new turbo If it was trying to run on its own oil it would have been up and away.

I'm leaning towards it ran away harder that was advertised and the injector pump isnt a happy item or the timing has skewed. Its just not making enough "noises of death" for it to be much else

Ive taken up Andys idea and have ordered some oil flush, coolant flush and fuel system cleaner. Only 150 bucks so figured why not.

Tonight in the carpark ill pull the batteries out, take them home to charge, and see if I can get it home - limp style tomorrow arvo.

Their oil flush is brilliant on dirty diesels,follow the directions for the first clean,after that its a treatment each service.
We did a mates HJZ 4.2 toyota before he shifted to Derby.He rang me when he got there asking where to buy it from.His tojo went better than ever,used less fuel and no oil for the trip.
I could tell the difference when I used it on the trytoo.
They make some strong claims on their website,from what Ive seen I dont think there is alot of BS there.

Hah, ah good times! Pajero started quickly this arvo. But it was billowing white smoke, huge amounts, was making me laugh actually. I could see a bit come from under the bonnet so had a look at I noticed a heap of oil near and behind he turbo. So I pulled the intake off and the turbo is dead, again.

The radiator is still full of coolant, no change in colour, expansion is still at the right level of water, and the oil cap shows no signs of water.

I'll buy another turbo and go from there. If the engine is dead, I'll part the car out.

Speaking with Dave, I've come to the conclusion either there is so much blow by (potentially) that it is drowning the turbo, or I've blocked the return line on the turbo and it is drowning. Causing the compressor to crap it. Which would then fail, the turbo with oil. I need to tow the car home tomorrow and have another look. At least this isn't 'bad' news as a turbo is far cheaper than an engine. So stay tuned for more horrible Pajero exploits...

Too much oil pressure to the turbo can cause it to bypass the seal to the air intake. Are you sure the turbo is dead?
