AH! the 3100. If you need, I do have the Chilton's and Haynes' manuals for my 96 Beretta, I'm willing to share info if you cant find the books on your own.
Nm the o-ring and valve cover gasket requirements. The 3100's biggest problem was that it kept spitting head gaskets. Strong, powerful engine, especially for it's size. I wasnt so lucky with the Beretta: The heads warped on mine, which is common with engine failures. Good luck.
