    Nissan Pathfinder YD25 start up rattle

    in Nissan Pathfinder Forum

    You mentioned "upgraded" and first I didn't know what you mean. Did you mean this duplex chain upgrade?
    I've heard that all these R51 Pathfinders and Navara D40 models have a weak lower timing chain? How this could happen? Both Pathfinder and Navara have the same 2.5 Dci YD25 engine?

    In the past two days I was trying to find more info on it and many owners complain online that their D40 Nissan engine blew up around 69-80.000km. It is pretty disappointing that these YD25 engine failures in a Nissan can happen. It feels like an engineering issue.

    So as I don't know when my timing chain and guides have been changed Im sourcing a suitable timing chain kit.
    Yesterday my mechanic told me that my Pathfinder also has this "simplex chain" which is the weak point. I told him that you mentioned an "upgraded" version of it and he knew straight that you were talking about this duplex chain conversion.  Im a little confused because there is so much information (that I hadn't known about it) of these duplex modifications and each offers different kit.
    Trevor... Is it true that after 2010 the Euro 5 engines need different timing chain kits? My Pathfinder is 2012 but I don't really want to order wrong kit.

    I found this site and they offer various options but in the options I can only see D40 and not R51:

    Hi Guys,

    Im new to this forum and hope someone can give me advice. I have a R51 Pathfinder year 2012 and it I can hear some sort of rattling noise on startup. 
    I owe this Nissan for couple of years but there is no service history and anything that would indicate that the timing chain has ever been changed.
    I thought I ask at what mileage I have to change the timing chain, tensioners and other bits? Is it could be a worn chain guide only or chain too? What parts should be changed?
    This engine noise makes me extremely worried.
    Any advice would be most appreciated.

    Thanks
