Triton Troubles

This Mitsubishi Triton came to us with a range of undiagnosed issues. So we took the opportunity to show you some things you may not be aware of when it comes to maintaining yours.

Good video , i had also a a 4d56 came in from another shop without the balance shaft belt fitted. Customer did not even know. Had some performance problems. Now i have a 4d56 did with hard start and not idling after it starts after 35 to 40 seconds with no trouble codes.

Thanks for the vid! Great info👍🙂

Great vid. Very interesting.

Mine had a small head gasket leak at the front of the engine. There is a tiny water gallery only about 10mm from the front of the block. Started at about 150K. Had new radiator, water pump, isolate EGR cooler etc but no-one could work out where the leak was. Eventually I felt a sudden increase in vibration (which I now know was the balance shaft breaking due to water damage. It had done 60K and I was planning to get the belts done shortly.) Mechanic couldn't find problem. 4 months later had a catastrophic breakdown when the balance belt pieces caught in the timing belt and caused it to slip. I could not afford a mechanic to fix it so took it home and bought another car. I got Covid soon after so had 2 weeks off work where I could remove and dismantle the engine while trying to not die. (got to get your priorities right hey?). Have been gradually rebuilding it since. Head crack checked and rebuilt, new camshafts. All the exhaust rockers were broken in half so full set of new rockers. New big ends. Bores and pistons were OK. Pulled out the balance shafts and checked their bearings (OK). Turbo was leaking oil internally and externally so had that rebuilt. Cost me about $3500 in parts, clutch kit, turbo and head rebuild. At least I now know this engine inside out so will be more able to maintain and diagnose problems in future. Not long until I get it in and back on the road. Moral of the story is it is cheaper to do a major disassembly to find a problem that wait until it becomes worse.

[@macro820]

You should open a partner shop in the states :)

[@mjhmech4903]

Lucky the b/shaft belt did not take out the cam / fuel pump belt! Have seen a couple sheer the tensioner pivot bolt on the main belt due to that same failure. Usually because owners have not had the T belts replaced @ 90,000km as per the schedule LOL

[@fryman2650]

+1 this, have also seen this happen.

[@RegulusNZ]

Yes what did he upgrade the turbo to , and was it a direct fit ?

[@deficator750]

Whoever sold him that car must of thrashed it

[@kennethreed9053]

Just curious what was the bill on this repair. I'm looking at getting a triton might need to budget for possible problems

[@MrDigger450]

Is there a shop in Perth cheers

[@Dan.U.]

I bought my 2007 Triton when it had done 235k km. I noticed a slight vibration usually at idle and and very low end of the RPM range. Came to know it is the broken balance shaft belt and when I did the timing belt replacement at 300K km I didn't replace the balance shaft belts because when it brakes again (as it would, because this happens due to lack of lubrication of balance shaft bearings by design fault with 4D56) there is a possibility broken belt entangling with the timing belt and breaking it as well. So I'm more than happy with this little vibration than higher possibility of a bigger repair given how old my engine already is.

what are the dyno results?

[@theodoreholland559]

my triton a 2012 automatic 2,4 model , hits the breaks while driving and then it stucks the second gear in the gear box making it impossible to speed it up. The only remedy is to pull over and awitch off the engine and start it back. Any ideas what is causing it ? the fault is P1782 and P1783

[@JennyWren1118]

Is this mechanic still in Sydney or is it closed down?

[@XIXjlo]

Hello from UK. My 2011 L200 2.5 DiD has done over 120000 miles. Do you think it needs a tappet adjustment as when the engine is cold, usually in the morning it sounds like somebody is shaking a bag of gravel in the engine bay.

[@hugokleynhans9595]

putt the right spec oil

[@TheEqualizer1]

Is this 4D56?

[@AlsAllAussieAdventures]

Buying second hand is always a risk, this does not reflect on the Tritons motor... they are a great, very reliable motor.

[@tommurray8312]

meh, mines been average camshaft cap failed at 100 000km, trashed the whole head - nightmare.

[@mjhmech4903]

Most Triton owners bitch like hell come 90,000km SVC cost time lol mainly due to the engine! LOL

[@b9625bb]

Nah not reliable at all , mine overheated at only 30000km Dont buy 4D56 engine

[@fryman2650]

@@b9625bb the overheating issues are an easy fix its caused by blow by, incorrect coolant and the wrong pressure rated radiator cap. All three should be changed if you ever buy a MN triton or challenger. They aren't too bad of a motor the older ones didnt have the issues like the tritons did but because the older 4d56 were built in Japan not Thailand they cheaped out on some things and redesigned.

[@b9625bb]

@@fryman2650 my issues are not because the coolant and already corrected radiator caps the problem was the head gasket blown because cant handle bigger Hp and Torque since i custom tuned the car with unichip making 255hp 550nm , only 30k and with original coolant from factory. After i replace the gasket the problem goes away

[@shanerorko8076]

I've never seen a balance shaft belt snap it must've been left on and they only did the timing belt, I have seen that before.

[@Dan.U.]

This is a common issue with 4D56 as far as I know. I personally had a broken belt on mine.

[@dingpongchi632]

It happens all the time

[@pauls3585]

Great video, thanks. Are the 2.4 Triton engines generally reliable? I have a 2018 Triton and a mechanic friend tells me the engines are lemons (based on 2 Tritons he has worked on recently)? He may be just a hater.

[@MRTPerformanceAustralia]

When maintained properly they are generally reliable.

[@pauls3585]

@@MRTPerformanceAustralia ok thanks. I take it they don't have the same cooling/block issues of the previous 2.5L diesels had?

[@Handlesplus]

We have a Triton and a Pajero Sport both with the 2.4T engine. THEY ARE BULLETPROOF!

[@chadkamira1176]

Have be pretty rough on the gear to kill one.

[@fryman2650]

If its a 4n15, they are much better then the 4d56(the motor he is looking at) easier to work on and they don't have overheating issues like a 4d56.

[@zappia08]

Hi what size is the turbo

[@creed2409]

I have the same engine in mine. It is low on power and has misfire code cyl 2, most notable at idle. I have already cleaned the inlet manifold with small improvement. Replaced the SCV with no improvement. I am now anticipating to find a broken rocker or replace injectors. Is there a valve/butterfly in the cylinder head that switches between the two inlet tracts? Are the injector fuel hardlines one use? Thanks from petrol car guy (diesel newbie) Yes I figured to check the fuel pressure on scan tool before working.

[@fryman2650]

Check injector lines for cracks, the return line which connects all four injectors and the pindles on the injectors themselves and make sure to replace the copper washes on the injectors while your at it. I dont believe there is any inside the head itself no. And yes they use hardines, sometimes can be prone to hairline cracks, if you do replace do not replace with used ones as they usually are married up to the injectors when first fitted, from experience some dont just straight fit but if you replace with brand new they will groove/mould to your injectors.

[@Dan.U.]

Just curious, what was the fault and did you manage to fix it?

[@creed2409]

Yes the misfire was blocked injector. I had already tried the fuel treatment additives and it was completely crusted over when I took it out. Job took all day as the manifold and rocker cover have to come off. Budget to clean the manifold and adjust valve clearances same time. Check the injectors are positioned correctly to fit the hard lines before reassembly. Mine were not quite lined up with the fuel pipe and were difficult to fit but did go on, I had already refitted the rocker cover and inlet manifold.

[@shaneaghan7013]

I think mine might be going getting a weird ticking under throttle that comes and goes whether its that and the injectors I'm not sure

Matenetehuake Dawson i heard the RHF4 modded is the go but needs new manifold

[@conmanumber1]

It's kinda b.s when one says bigger tires are hard to get off the mark and require more torque. When increasing tire diameter it's very common practice to change diff crown and pinions to suit tires. This will bring it back to as normal.

Have 2014 mitsi tryton 4×4 with 97000k . Just purchased and have an overheating problem. Had the veichal serviced today ,was figuring a faulty thermostat and had removed. On way home temp still rose up to the three quarter mark and i turned on the heater. I will admitt that i had been crusing at up to 120kph. Wot do you suggest i look at next ?finally i boughht this veichal with a 12month mechanical warranty.

I know someone had same issue in same model at 120,000km. It’s a fault that Mitsubishi are aware of. They replaced the engine even though it was just out of warranty due to his good service record. Replacement motor is $13,000. Get it looked at before it gets worse.

[@rorymagnatheredking]

With your Experience do you prefer the 2.5L or the older 3.2L turbo diesel engine with the timing chain?

[@almostbutnotentirelyunreas166]

Never seen a diesel engine with 'clean' oil, not even after a full lube service. Watcha on about 'black grunge' in this video, there is no build-up, only the normal residue?

[@Honey_Crumbs]

'Residue' is not normal, an engine with 12000 hrs on it will look shiny clean if you change the oil regularly, like around 250hr intervals.

You will need special tools to do the job.
