Morning all I am trying to solve a constant oil leak from the top end of my 2009 C4 Grand Picasso 1.6 HDI. I am planning on changing the intake manifold oil seals but am concerned about taking the injectors out to remove the manifold as I recently had the injector seals replaced and dont really want to disturb them How easy is it to remove the manifold. can it come off without removing the injectors, and are the fuel lines a difficult job. Any pointers would be appreciated many thanks
