Mitsubishi engine 4m41

Hi Nick d.

I second marq's reply, don't run it and get it inspected, I had similar problem with 2.8 diesel in a Triton, ignored it and ended up costing me $ 3000.

Good luck.

friend had the 3.2
rattly tractor motor what i reckon..

timing chain let go, and bye bye motor....... bye bye..
DONT DRIVE IT.
replace the timing CHAIN IMMEDIATELY

or say bye bye to your engine, VERY SERIOUS.

Marq : >>>It's a $25 part - takes <1hr to replace. ????

Is this your 1st hand experience ???? It's a 4m41 TD 2006 on & yes it's same as the Pajero with that same engine .

Q If so did you need to remove rocker cover ? ....If so how did you go about that ???? what did you have to remove from engine !!!!

I have spoken to Mitsubishi & they tell me that they have never done one with these K'S ....

cheeres .... P.S IT IS PARKED UP TILL FIXED !!!

Hi. I think you may be mixed up with engines that have a Timing Belt. These are replaced at 150k

Apologies yes I did

Just had a quick look at my service manual i know mines a 2.5 but are the 3.2's running a belt or a chain ?? maybe jump on newtriton forum someone on there would def know . Mine having belt should be done at 60, 120 ,180 .

Nick the pics below give some idea of what they should look like compared to what can happen if they left too long.
In extreme cases the tensioner has been known to have been cut in two where it falls into the timing chain assembly sometimes causing complete engine failure.
There is also a time lapse video of how to change it on an NM-NP Pajero.

NM-NP upper timing chain tensioner replacement.

If your engine is the later common rail engine the procedure will take quite a bit longer as the fuel rail assembly must be undone to allow the rocker cover to be removed.

Thanks very much for this reply :

>>>common rail engine the procedure will take quite a bit longer>>>
Q do you know if the injection pipes can be re used ?

cheers

Nick, from memory they can be re used 5 or 6 times.
I think it recommends in the service book the number of times they should be re used.
It is also recommended that tappets are done at the same time as the rocker cover is already off.
If you are going this far I would also recommend removing the inlet manifold and cleaning all the EGR muck that WILL be clogging the inlet manifold and inlet ports, see pics below.
Regards Andrew.

I have had engine inspected ... stretched time ? chain guides look to be ok
Quoted $ 2700 ... head off 15 hr work parts around $ 800 +

any input maybe helpful

cheers

Gooday Justin : pajero 2002 I dont think we are talking same engine ...4m41 TDI 3.2 ...But mine has got a slack cam chain , A bit under $ 3000 to fix it 16 hr work ( head off ) + parts "Not Mitsubishi's best work" , I have replaced chain tensor for now which has helped .
cheers
