Is the exhaust manifold prone to cracking in any certain spot. I bought an 85 318 and when I started it, it sounded like it had a bad rod. Then I started another car I bought, which had a bad rod. Very different sound. I am thinking either cracked manifold or stuck rings. I can't find my compression tester as of right now, so I thought I would ask about the manifold until I find it. It also seems to be running rich right now, and the inspection light is on.
No, I am not driving it.
