MQ 4N15 valve clearance

MQ 4N15 valve clearance

Postby WUNSIE on Wed Mar 11, 2020 3:01 pm

Got my Triton booked in for its 48 month /60,000km service, its only got 37,000km on it , I asked the service dept does the clearances need checking or is only a visual/ listen as they call it, he said they should of been done at 36 months/ 45,000 km. I said my hand book states its 48 months 60,000 km,
Said he needs it for a day, engine runs perfect I,m just abit concerned it might not be the same if they start pulling stuff off to get to them and check,
anyone else had bad experience afterwards or am Iable to decline having them looked just yet due to the low km,
Cheers

What year is yours? 2016/17 were 45000 2017/18 were 60000km. This is a good rescource to check

The inlets will be tight I am sure. They always are. Not by a lot, but enough. And the exhausts will be loose.

As long as your dealer knows how to use the MUT service manual, and can read, its not hard.

Thanks Dibby,
was hoping you would reply,I Purchased it new in March 2016, the service bloke said it should of been done at 45,000 km, but it wasnt, thats why I asked the question, as my service book states the valve check @ 60.000km , checked invoice and no mention of valve clearance work @ 45,000 km,I would of picked it up on the day if it were carried out as I like to check what was actually done, and besides they always give me a run down on what was performed. He said I need to leave the vehicle with them all day, hope they got somewhere for me to have a kip as I start work at 1.30am and its booked in for 8am same day :roll:
Would it be okay to say let the check go or would it come back to bite me in the butt

By the way he did say if I have Capped price servicing for 3 years it gets done at 45,000 km but if I have 4 years capped price servicing its done at 60,000 km ( which I have )

Just checked on the link you provided why is the 2016 Triton state every 45,000 km, yet the same year in the Pajero Sport states 60,000 km ( same engine)

Yeah Paj Sp and Triton althought same year (model year) the engine is Basically the same, but there are a few differences. Im not aware of the differences internally, but the external differences were carried over to the Triton in 2017/18. The easiest way for you to know is if you have this pipe on your engine.

If you do yours is an early one and valves are done at 45. If you dont have this pipe then its a later one with valves at 60.

The oil capacity also changed. Early was 8.2 inc filter, later is 7.5 inc filter.

The service book (i am always told) is always correct. But it is not unheard of for these to be mixed up.

If you have CPS then you should get it done, as in reality you have already paid for it in the purchase price.

Thanks for the above Dibby, I went and checked mine, I have what looks like a vacuum pipe running to the turbo, yet my handbook states 60,000km , another question do the camshafts have to be removed to change the (shim/buckets ) and is there anything I need to check when I pick the ute up after the work has been done,starting to feel a bit apprehensive, just hoping the person doing the clearances knows his stuff, I might be worrying about nothing,
Cheers Wunsie

They are old style tappets, with screw and locknut, so no cams out.

Nothing you should need to check.

Sometimes too much info is a bad thing, but its good that you care :-)

Mine is a 2019YM produced march 2019. All the vehicle stickers and plates and rego papers attest to this. But it still has the oil breather to the turbo. I have googled the 2019 model at a few sites and all photos still show the turbo pipe. I'm totally confused now. Are we talking about the rubber hose from the rocker cover to the turbo inlet or have I got it totally wrong? And does the 2019 still have screw and locknut as well?
Cheers.

The pipe we are referring to is in my post above. It has a red highlight along it. We are not talking about the rubber hose to the rocker cover. If a Triton has this pipe in this exact position, then it is the earlier model. Your model will not have this pipe in this exact position, therefore will be the later model.

Regardless of MY the valve gear is exactly the same. Screw and locknut on all 4N15 variants

Thanks Dibby. I seem to get confused easily these days. I read too many newspaper road tests where the writers get it wrong quite often. There was a claim that the 4n15 has shim over buckets , similar to the old 3l hilux and half the bloody motorbikes I owned where I I learned to loath bucket shim adjusters, measuring gaps, pulling the valve gear apart and marking everything down on a piece of paper writing little plus and minus amounts alongside every shim and then trying to change around what I had and buying a few new ones to make up the rest. I really learned to hate them. Thanks for that.
Cheers
