    Default Leaking return hose o rings on 407 2.7 hdi

    Hi there.

    Im new to the website.

    Recently bought my 2nd peugeot after a good run out of a 406 hdi.

    I bought a 407 2.7 hdi. Its a nice car but i recently found diesel pooling in the tappet covers on the front and rear bank. Looks to be the return hose o rings.


    My question is how difficult are these to replace and where would be the best place to source the parts.

    Thank you.

    I got 'em here:

    Easy to replace. Pull the clip off with pliers. Just don't put the new ones on dry, dab a bit of diesel on them so they slide in easily. You'll destroy them if you don't do that. Pliers to slide the clip back in. A magnetic pick up tool is handy if you drop the clip
