Least I can do. When we catch up, happy to do an oil change on it for you etc

[bagmaker]

How come it blew up if an injector failed?
Is that common, like, what would occur internally?
I surmise too big droplet =non-combustion / hydraulic lock = piston failure? Would that be the case?

The injector either doesn't atomise properly and the fuel washes the oil from the bore causing the rings to gouge into the cyl wall creating enough heat to melt the piston on the way past. The metal picks up and tears more of the piston, jams the rings into the piston grooves and then the intense flame from the diesel exploding burns a hole down the side of the piston..... all that in a few seconds, the piston comes to the top of the bore 2,000 times with the engine running at 2,000rpm, so it passes that section of the cyl wall 4,000 times a minute, once coming up and again going down, and that is at only 2,000 rpm, the damage is done in the blink of an eye, after that the raw diesel is being sprayed past the piston each time it comes up on a compression stroke and that fuel is going into the oil, and diesel is not a good lubricant, so more damage is done if the engine continues to run with this damaged piston.

I agree with what Bagmaker has said. The hydraulic lock up , fuel not atomised sitting ontop of the piston, piston comes up hits solid fuel hence piston damage.. And you lot think I an just a pretty fat face

"tanks" here---
I'm having a lot of difficulty in getting answers to my questions. It appears that there is a lot of pass-the-buck going on and the legal action has not started yet. It may be some time before I am on the road again while we/they work out who pays for the damage.
In view of the latest situation, I will be holding out for a new engine or a factory rebuilt engine not at my cost.
This is the second attempt to have my questions answered:-
Gentlemen,
I refer to my e-mail of 27th October 2015, [18:32] requesting information in relation to the damage to the engine of my motorhome which remains in your possession.

I am concerned with the evasive reply I have received.
Your e-mail of 27th October 2015, 18:45, does not address the questions that I have asked, but simply informs me of the sump capacity of the engine, and that a full report will be carried out after R. Moore P/L have tested the injector/s.

I again ask for answers to the items I have raised in my e-mail, specifically
para 1; relating to the oil level light warning
para 2; asking which oil light was showing
para 3; relating to low oil pressure in a recondition engine
para 5; what obvious signs of oil loss were visable

Your reply to these questions is not dependant on any of R. Moore P/L findings, and I fail to understand why you elect not to address these questions.

A further question that I would like clarification is were all four injectors sent to R. Moore P/L for testing, or only the one injector which you identified as being possibly defective.

Para 4 of my email simply asks if these symptoms reflect an “overfuel situation” which could have caused the damage. I am of the opinion that Skippers Trucks as the agent for Iveco WA should be in a position to inform me if faulty injectors could possibly cause this damage without waiting for a report from an external business.

I await your reply.

Keith.

I don't think you are a "pretty fat face" Dot--- a bit thick at times but not fat.

Does this do any damage to the other pistons/rings etc or only the faulty injector piston.

It is time to get your consumer affairs people involved, it is amazing how things can change when they start leaning on people, and this is from personal experience. Will get your answers and some action. FAST

It would have been happening to at least cyl 2 as they mention it was missing and the scan tool showed cyl 2 to out of spec, so they swapped the injector to cyl 1, then it failed under load, so at least 2 cyls will be damaged in a motor already remanufactured engine. Put this to the consumer affairs people, what faith could you put in an engine that would be reconditioned a 3rd time? You want a new engine, the original engine was near new with very few kms on it and that is what you want to rectify the problems caused by these people, not a 3 times rebuilt engine.

Skippers Trucks are removing the head Monday to gather "evidence" and work out what has to be done to fix the problem. They will have the experts from United Fuel present to observe what damage has been done and to work out who pays who for what.
I have told Consumer Protection that I require a factory crate engine or a new engine so I now wait for the next report.
Keith.
EDIT:-
e-mail from Skippers Trucks informs me that they intend to rotate what they think is the faulty injector between all cylinders and test the injectors that way. They are going to use the Easy Diagnostic tool to do something. They think that the bore has now picked up on No. 1 cylinder.
All of this means "Jack S**t" to me, so I am at their mercy. I have suggested that they also involve their legal department as there looks like being a tort action initiated by me in the near future.
