    Big end bearings, Tdi 300?

    Hi All, I'm a little bit worried, the landy has a definite rattle when cold, more so than it used to have., Still the same when hot,just wondering where this is heading, or should i just shrug it off as a landy thing, could be the same in another ten yrs, Have changed to 20w/50 engine oil.


    Cheers Sumo

    Guessing noises without further info is a mug's game. At what phase of operation do you hear the noise? Under load? At idle? At over-run? Find a suitable mechanic to have a listen.

    20W-50 isn't necessary....

    Listen to bee utey.

    FWIW big end clearances blowing out on a Tdi is a distinctive knock (more a bddddd ) at high revs on the overrun and a more subdued knock (bddddd) at revs under power.
    When mine were trashed that was the only time they could be heard.
