HI All looked all over the net, so my last hope is here. lol. I have an issue, while trying to instal a catch can at the rear of my M156 engine inlet manifold I snapped the vacuum fitting just under the PCV valve. I found out that Mercedes will only sell me the complete intake manifold..( Mercedes area vey special company ) which is a little ridiculous, but these days what's ridiculous.lol. so has anyone been able to remove the vac fitting without braking it. also some good mechanic broke the brake booster vac hose outer retainer clip, if that also can be removed would love to know how..
