Re: Snoopy (Pajero 3.2Did) died on me today!
Thanks Roelf

I spoke to them yesterday and they promised me a complete and detailed report today as well as a quote. I took some extra blood pressure pills this morning in anticipation :?

These are the photos so far that they sent on to me last week when they took out the engine.

They have indicated that the #1 piston has a crack/hole in it and the cylinders still look pretty decent and within spec, but will await 'official' report before they quote.

PS - I am starting to miss her and getting itchy I must admit.

Good Luck CATS - hope the final number isn't too depressing :shock:
Re: Snoopy (Pajero 3.2Did) died on me today!
Hello Cats
Will they be able to tell you why it happened?
Overfueling, was the piston already damaged when the diesel pump packed up, etc?
What are the early detection signs to look for?
I think all of us with high mileage Pajero's are worried about this scenario.

Re: Snoopy (Pajero 3.2Did) died on me today!
To those interested. Here is the report on the damage and some photos.

To repair engine and do some other stuff as well while it is out, like radiator and inter-cooler flush plus turbo service/kit come close to R40000! I am fixing it properly and not taking short cuts. I am going ahead with the repair and at this stage does not suspect foul play on the side of Alan Black when they did the diesel pump and injectors less than 3000kms before the piston failure.
I believe that the piston just was not manufactured to handle the stresses it is subjected to forever and as such will fail eventually. Only diamonds last forever they say( some Toyota owners will try and convince you that Toys also last forever but I disagree :-) ) It is a blow to the system and the piggy bank but at close on 300000kms I can probably not complain too much.

There are NO warning signs and also NO tests that can be done to detect this early before it goes South, as far as I can gather which is a bit of a bummer. Maybe someone can research this in more detail? Furthermore I believe that I have done ALL one can realistically do to prevent premature failures with EGT probes, cooling down engine after prolonged hard use, no redline revving etc, very short oil changes and religious servicing while I had it over the last 220000kms. I also had injectors checked and replaced at 100000km intervals.

Usage history: I have never used 2SO consistently(only once used) and have also not blocked off EGR since I bought vehicle on 80000kms. I tow big loads regularly off road. I do not know how the inlet port look at this stage and if it has any relevance.

Please note that this report ONLY relate to my vehicle and NO deductions or other assumptions can be made from it!! The report is also not to be used to point or un-point fingers but are merely shared as knowledge enrichment!!!

Comments and donations welcome :-)

Hi CATS,

Thank you for posting this & the report.

A few questions:
1. Who paid for the report?
2. Having read the report, unless every other piston is in a similar state, then the failure must surely be related to something that happened only in this cylinder.

I can only think of two things that would fit that description - maybe there are more:
2.1 Injector not atomising properly (I am not saying when)
2.2 Oil spray under piston becoming partially blocked maybe.

Pity (and maybe surprising) that the forensic report did not test the injector spray pattern for that cylinder and did not report on the other pistons (to look for incipient failures) and their injectors also.
3. What would it cost to get the report extended to cover those other aspects?
4. If it can be guaranteed that the actual injectors, correctly marked per cylinder location, and untouched by Go Power / Alan Black can be tested by or under the watchful eye of the forensic investigator I would be willing to chip in some moolah to get such an extended report. Maybe others would consider likewise.

We all need to understand this further and it is for mutual benefit of all of us driving the non-common rail 4M41.
Re: Snoopy (Pajero 3.2Did) died on me today!
Report was paid for by Go Power to determine if there is a claim relating to the diesel pump and injector work done by them previously. I will ask them on the possible extension of the test. I am willong to bet that if I replace only piaton #1 that I will soon thereafter have another similar failure on another piston. I believe it to be heat fatigue due to age.

Will revert back.

Super informative. At a huge cost

Severe thermal overloading.... on one piston only??

Just some updates.

I have requested them to extend the tests to the other pistons as well to determine the state of them.

In the mean time I have agreed to the fixing of the engine. Go-power quoted on "replacement" pistons and rings(nice name for pirate parts :-) .) The costs are slightly less than the original Izumi pistons that Mitsubishi use and are made/sold by a company by the name of Arco. I have done some research and could not get much and as the cost is not that much in the bigger scheme of things me and Bradley decided that we will rather fit the originals, even if I have to wait a bit for parts.

Now putting the Mitsu parts monster to test! It seems that there are 3 different type of pistons (nice read here on the Izumi piston by Entabeni by the way - https://www.pajeroclub.co.za/forum/view ... 45&p=35300 )
Mitsu/Imperial list and A,B and C type piston for the 4m41 engine. Piston number ME191470. The type A, B and C are listed on the top of the piston. Imperial list 30 type A in warehouse stock, 2 Type B and zero type C. They have 2 ring sets in stock. So not too bad stock wise on a non service item? As luck would have it mine are type B. So I need two more ex Japan :( .

Bradley at Go-Power with the technicians at Mitsu are trying to determine what the differences are between the lot and see if we cannot maybe use the A type. Especially as we will be replacing all 4 with the same. They are all the standard size it seems and I still will be fitting standard size as wear on the cylinder is still within spec and no oversize are needed. If we cant use the A type I would have to wait 4 weeks for the stock from Japan for B type. :cry:

I tried Google to find what the differences are but so far no luck. Anybody else maybe know or want to chance a guess ?

Hi CATS,

As always, thank you for keeping us posted and for requesting the additional tests.

Please let us know where we can deposit a contribution towards those.

Amazing that there is no wear that requires a rebore after all those km! Especially on the cylinder with the failed piston.

From here I found the following:

"Vertex offers A, B, C, D, sizes so that the customer can properly fit each piston to the cylinder. The difference in the sizes is 0.01mm (0.0004") increments with A being the smallest and D the biggest. When a cylinder wears, the customer can choose the next larger piston size to regain the proper factory fitment."

So maybe the info re all being the same size is worth questioning.

If I find anything else I will let you know.
