How to adjust valve clearance on Mitsubishi Triton MR and MQ 2015 to 2022

This car was in my workshop to do 90 000kms service. including valve clearance adjustment.
In this video, I am showing the important and easy steps to follow. please watch the video from start to end.
you can use this procedure on 4N15 MIVEC engine in Mitsubishi triton MR /MQ 2015 & Pajero Sport to 2022. #primetech Automotive
#valve adjustment #triton valve adjustment
Torque specification as follows.
Tighten the bolt on the engine front side of the fuel injector holder bolts to 1.1 ± 0.1 NM.
tighten the engine rear side bolts of the fuel injector holder to 180 ± 1 degree angle.
again, tighten the engine front side bolts of the fuel injector holder to 90 ± 1 degree angle.
35 ± 5: Tightening torque of the fuel injection pipe (unit: NM)
rocker cover bolts - 4 NM then 6 NM
Inlet valve Clearence - 0.08 +/- 0.03 mm
Exhaust valve Clearence - 0.16 +/- 0.03 mm

Thank you kindly!

Good video mate 👍🏻

thank you

awesome, thank you😊🤙🤙

My pleasure!

Hi, I thought this Engine comed with hydraulic valve lifter? My MQ 2015 came with 2016 4N15 engine. Thanks for video I saved in my favourites.👍

[@PrimeTechauto]

Thank you

[@juanvergara6756]

Hola, por favor cuál es la holgura a la que se calibran las válvulas?

[@daneedwards81]

Great video mate Do you have a part number of the valve adjustment kit ?

[@PrimeTechauto]

Hey sorry , it doesn’t come as a kit anymore. You need to buy the rocker cover gasket , copper seals , injector tighten bridge washers,return line o rings , all seperate.

[@salekanayake8416]

Thanx mate. Have you done a cracked cylinder head repair job on this engine 4n15? I heard it’s a common fault on this engine after valve clearance work people cut the injector seat fo remove corrosion carbon build up with a reamer too much reducing the thickness and over tighten injector bolts .

[@PrimeTechauto]

Yes, I have done some jobs with coolant leak. it's not just because of cutting cylinder head. its more towards overtightened injector bolts causing to this.

[@nickcOfficial]

My car needs this just checked it it’s got a lot of gunk/carbon built up around the injector. Needs to sort it

[@PrimeTechauto]

yeah , I have seen that happens lot when the injector seal leaks.

[@nickcOfficial]

You’re local to me I’ll get In touch for a quote

[@salekanayake8416]

Hi mate , is it good practice to bleed the injectors first to get rid of any air trapped in the injector pipes by starting car before connecting the injector wires ? I saw few other people suggesting this step in diesel cars Or it’s not required in modern common rail engines due to high pressure pumps pushing most of trapped air to return line without any air lock issues Thanx

[@PrimeTechauto]

it doesn't require in common rail engines. since the pressure is too high, it's not safe doing this. just use the feed pump on the fuel filter and pump about 20 times and start the car. this will help to bleed the system.

Great video, but please dont have the music playing as a lot of people like to have the captions on to check on what you saying and the words to the music overide what you are saying!.

[@PrimeTechauto]

Thank you for the comment. Im so sorry about the music. I can’t delete the music now.

[@salekanayake8416]

So at TDC you have to do the two adjustments on each of the - number 1 abd 2 on intake & number 1& 3 on exhaust Then turn engine 120 clockwise Then do the two adjustments on the - number 3, 4 on intake & 2 abd 4 on exhaust Correct? Thanx mate

[@PrimeTechauto]

Yeah.

[@adam6ism]

Excellent video thank you but the music is very distracting

[@PrimeTechauto]

Thanks for the comment. I’m so sorry about the music. Tried to delete the music but it’s too late now. Then I have to delete whole video.

[@avikerrisna4766]

Exactly. Take that rubbish music OFF !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@redfalcon4469]

Nice video, I have pajero sport with this engine and I have completed almost 120k km or 60k miles. Do I need to do it now or wait to 200k and replace the injectors at the same time. What do you think? I use my car mostly on the highway with no towing.

[@PrimeTechauto]

Hi redfalcon Yeah it’s due for valve adjustment and fuel filter too. You can do the valve adjustment and required service items according to your region & service schedule. But you don’t need to replace the injectors at 200k if there’s no problems. Thanks

[@marlon6931]

Hi im new subscriber just want to ask how many kilomiter or miles before doing the valve clearance adjustment

[@PrimeTechauto]

hi It depends on the year model of your triton. Model Year 2016 - every 45000kms / from 2018 every 60 000kms...

[@devilzmishimoto8492]

Hi, I’m in the process of getting my pajero sport 4n15 engine for valve clearance adjustment. I’m just wondering how long did it take you to do this job? Cheers

[@PrimeTechauto]

for a proper valve adjustment takes around 1.5 to 2 hrs. cheers.

[@PaulDockley-yp1vw]

Hi Thanks for a great video ,can you explain the injector tightening bolt sequence a little more ,front bolt 1.1 NM rear bolt ? 180 degree?and front bolt 90degree again ? Cheers and thanks .Paul

[@PrimeTechauto]

Tighten the bolt on the engine front side of the fuel injector holder bolts to 1.1 ± 0.1 N·m. tighten the engine rear side bolts of the fuel injector holder to 180 ± 1 degree angle. again tighten the engine front side bolts of the fuel injector holder to 90 ± 1 degree angle. 35 ± 5: Tightening torque of the fuel injection pipe (unit: N·m) Thank you for the feedback. hope this helps

[@PaulDockley-yp1vw]

@@PrimeTechauto Firstly thankyou for such a quick reply you're amazing 👍 Im no mechanic and dont really understand the degrees part of the tightening procedure,is the rear bolt tightened until it contacts the face and then simply turned another 180 degrees , obviously I have no idea .just interested in how this all works and the front bolt at 1.1 Nm doesnt sound very tight then 90degrees more ? Cheers Paul

[@PrimeTechauto]

@@PaulDockley-yp1vw yeah , just make sure everything tighten according to the procedure given. If you don’t tight the. Properly there may be serious damage can occur. I’ve seen that many times. Over tighten bolts can cause to built internal cracks in the cylinder head. Also loosen injectors bolts can pop out when compression build. Have seen this too. Burnt harness. So if you not sure . Highly recommend to consult a mechanic.

[@PaulDockley-yp1vw]

@@PrimeTechauto ,Have no fear ,I won't be doing it but I do like to know what is done and roughly how much it should cost before paying out good money .Ive heard of others with cracked heads due to the tightening of injectors being wrong .

[@PrimeTechauto]

@@PaulDockley-yp1vw roughly about $450 AUD (including genuine parts and labour)

[@HW601717]

I’m confused about the Maintenance Manual, and if I have a MIVEC engine. Are all MQ tritons 4n15 MIVEC? I have a 2015 triton

[@PrimeTechauto]

yeah, all MQ & MR & also Pajero Sport from 2015 (comes with 4N15 engine) used MIVEC engine. If yours 2015 MN triton - it doesn't have MIVEC system.

[@salekanayake8416]

Hi sorry completely not related to the topic in this video, I have a small issue in my Triton mate, I recently got my intake and EGR carbon buildup cleaned on this engine . The problem is now It’s making a funny noise after I stop the car for about 5 seconds like a weird buzzing noise. Had a quick look online and a few forums say it’s due to egr and throttle trying to adjust , open , close and reset and might need a throttle / EGR relearn Is this correct? Are you aware of this issue? I am in Melbourne is this something your shop can fix if I bring the car to you guys please?

[@PrimeTechauto]

HI Salekanayake, yes I am located in Melbourne. check my business name and give me a call. Thanks. we can check this. if it is throttle resetting sound - it's completely normal.

[@moises981]

Hello, when do I have to do this service? my L200 has 86,000 km

[@PrimeTechauto]

If it’s MQ or MR (model year after 2015) It’s better to do it in 75k service.

[@daveo1446]

Im not convinced you did that right... when you tighten the lock up the adjuster will move...

[@PrimeTechauto]

I’ve been doing this over 15 years. Never had issues. It won’t move if you tight it correctly. (Not over tighten the lock up nut) You can always use offset spanner with a screwdriver when tighten the lock up nut. Cheers

[@renzoantonio1572]

We do valve clearance every how many kilometers on our 4n15? 40k? 50k?

[@PrimeTechauto]

every 75k
