I have a 1969 280sl automatic that appears to need a new head gasket and head check. Can anyone give me a step by step process in how to take the head off? I have a mechanic friend who is great and going to do this for me but doesn't speak or read english. And, I don't speak much spanish! He has done this before on other cars but not on a old Mercedes. I basically need to translate it to spanish. I am not much of a mechanic so if anyone can help me I would be grateful. I basically need to tell him how to do it and what tools are necessary. Thanks a lot!
