Hey fellows,

I'm new to the forum and I've got a few questions. My '91 CE is in need of a new head gasket. I'm not a professional but I have rebuilt a few engines for myself. I'm wondering if I should tackle this job or bite the bullet and pay a professional to do it. I know that if I do it myself I'll need the shop manuals. Which one and where do I get it? The engine is the M104. I've also notice a distinct noise in the rear. I first thought that it was road noise from my tires, but I've rotated them and it didn't help. What do you think it is? Finally, if I do the job myself, where do I get the parts? Thanks! jmerc6
