Guide rail pin removal issue
I am in the middle of replacing my dead M117 with a newer M117 in my 280SEL. Prior to installing the new engine, i am doing some maintenance; new front and rear seals, valve seals, gaskets, chain etc... to the new engine.
Now the issue. Apparently the PO of this engine did not ever want the pins for the chain guides to come out, because they are way in there. I have a homemade slide hammer which pulls pins fine in my old engine, but will not budge these. I've soaked in penetrating oil, heated them with a heat gun, pulled with my slide hammer, but none of them will budge.
