Exhaust manifold leak? Hi allI suspect that either the diesel injector seal or the inlet manifold gasket are faulty on my 2007 C4 1.6 HDi 16V (92hp)The Injector seal seems to be fairly easy to replace, but I've a feeling the inlet gasket is abit more involved. Is that correct? If so, what does replacing the inlet gasket involve? A quick step by step guide would be awesome!Thanks all By Southerncitroen On Sun May 23 2021, 07:10am
