Thanks 4ePajero.
Anyone have any comments regarding use of AE pistons for rebuild? My mech reckons he can only get 3 Mitsu pistons and the 4th would have to come from Japan and who knows how long that would take (he was told 4 months).
Any opther options?

I would not have a problem with AE.
Alert Spares should also be able to source pistons (... and rings, gaskets etc)
For advice checks etc. you can also look at Mizco in Kimberley Rd (next to Bosch, Diesel Electric)

An update for those who are interested....
My mech found that the throttle butterfly was quite sticky and that there was a carbon build up issue. There was also a large amount of "gunk" in the air intake pipe past the point where the pipe from the tappet cover connects to it. He had to scrub the gunk out as it was pretty much restricting the air intake pipe to abround 50% of its original capacity. A seriouss moking gun wrt the cracked piston due to overfuelling.....the Pajero is now back together and I collect it tomorrow
Missed the old girl for the last 7 weeks and will be heading to a 4x4 trail as soon as I get a chance!
Thanks to everyone for their input previously. Much appreciated.

Good to hear TranskeiCowboy,
I hope the repair gives your GLX a new lease on life and that the culprit was indeed the intake and butterfly. Good luck & enjoy!
Regards

The failure may thus have been caused by the recirculating system.
Good reason to consider an oil catch can. (Do a Google search on the web)
I am considering this for both the DiD and the VW V10.

There are many pages of discussion on the 3.2 carbon issues on the newtriton.net site. I already had the issue on mine at around 65K. On the Triton the intake pressure sensor is quite sensitive so it picks up the pressure change when there is about a 6mm layer of gunk in the intake.
The newtriton guys solve the problem in a combination of 2 ways. Firstly the oil catch can to remove the oil in the intake that usually mixes with the carbon and makes it stick, and then partly blocking off the EGR. At first the guys blocked off the EGR completely, but that often gave the engine check light and sometimes the vehicle went into limp mode. Then some of them put a 6mm hole in the blank off plate and that seems to work, but there are constantly guys sharing their latest experiences.
With the 6mm hole, a lot less carbon can get through and with the oil removed, the carbon doesn't stick to the intake as much.
My Triton will be out of warranty in October, then I'll do these mods, but for now I'm sticking to 50ppm only to reduce the carbon produced.

Gerhard, where can I buy one of those catch cans and what do they go for?

Try Google, but it is so simple that someone in your business can make it yourself (add 2 for me!

)

Yip, google is our friend

That's neat and cheap enough...just has a bit of a boy racer look with the red anodizing.

Thansk everyone for all the info. Hoping the Pajero now continues strongly again.
I am definitely going to hook up a catchment system as well.
