    Have you removed the cam sprocket to see if the locating thingamajig isn't worn?
    The timing is supposed to be easy and not easily adjustable except pump timing.
    But I think you should look for the fault somewhere else.
    You can also check out the lift pump, intercooler pipes (de-lamination) and air filter. They can also influence performance.

    No, jfh, all is in order there. Timing is confirmed spot-on now in all respects, at least I'm sure of that. And it runs very well except for a bit of a lack in top-end power.

    Lift pump seems OK (fountains out the fuel filter housing bleed screw), fuel filter OK, etc. We'll see in time what happens...

    Interesting, mine looks a bit different.

    Ah, OK. Just about 10 years younger than mine then. :-)

    Antvz.
    Re your camshaft/valve timing....if I may offer a comment.

    When installing the belt, all marks aligned, the belt is installed with the idler in position. With a slight amount of belt slack (on the idler side), as the tensioner is adjusted to 15Nm., it can (pull) rotate the camshaft (taking up the belt slack) thus altering the valve timing.
    Because the IP sprocket is loosened, flange pinned, the IP timing is not affected.

    I recall this happening when I replaced the belt on mine.
    I also adjusted (advanced) the IP.....slightly noisier but much livelier.

    With regards.. Michael

    Just note that LR brought out a service bulletin in '98. Among the changes where the belt tension.
    It was changed from 15Nm to 11Nm.

    Hi All

    regarding the cam/pump timing on the 300Tdi, both of which are affected by cam belt tension, there is only one way to get this set up 100%.

    When I still had my 300Tdi I used to go to Brian Cotton of Landyonline, who had the Snap On Tools pulse to strobe gun attachment. With this timing was set to 10 Degs BTDC at idle with timing light gun and engine ran tops every time. Brian sold that tool when he closed his workshop.

    Hope this helps.

    Boobook, thanks and a pleasant 2018 to you too. It's been 20 000 km since the belt change and she's going like a Boeing. I learnt a lot during the process as well.

    George, I think we must also add to this LandyWorx sets the timing like this. I speak under correction though but that's what I remember from this forum.

    However, there's good news for those who can't get their paws on such a gadget.

    IF everything is in spec and your pump has been set correctly to factory spec, all you need to do is line up all the timing marks properly and you're sorted. You then have a nice standard spec setup that won't grenade on you in the middle of nowhere.

    Hi Anthony

    it was me who told Peter about this gadget and where to get it back in 2011. But you will not have a 300Tdi working at peak efficiency by simply lining up the marks.

    Those who have driven my 300Tdi know how well it runs. Very accurate timing was part of the recipe.
