Hi : Does anyone know of a "maybe common" problem that the 3.2 TD trition / pajero motor , with a noisy timing chain , 160,000 ks
My triton 06 has developed a rattle in the motor that sounds like a timing chain , a search of the internet talks of timing chain guide problem !!!

cheers

If it's anything like the Pajero 3.2 DiD - you need to replace the timing guide every 100,000k otherwise you might be up for some serious $$.

Do not run the engine without inspecting -

It's a $25 part - takes <1hr to replace.

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.

Rob

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 !!!

Sounds like normal servicing by Mitsubishi to me Nick. Most diesel motors like the 3.2 , Toyota or Nissan for example require the timing chain to be replaced at 150,000kms. has this been done?

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

Hi Nick i have a 2010 triton 2.5 . I would most likely say value clearance . They say they should be checked every 30000ks or so. I know both 2.5 and 3.2 can be alittle noisy if there not done . maybe have them checked also

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.
Regards Andrew.

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 faced some issue with my Mitsubishi Pajero 2002 engine with a noisy sound like “tik tik”. I have checked this issue with my mechanic and found that its piston and block part need to be replaced.
And we have done such swapping by purchasing some used engine parts from http://www.hiperformer.com/automotive and the problem was sorted out.
So just to solve your problem you should go with your mechanic and replace your engine parts as suggested by him.
