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.

thanks for the reply

It is definately not a rod. i have heard enough of them to know that. Wrist pin would be my thought. It is very metalic sounding. not like a rod clank though. almost sounds like there is no exhaust manifold.

here is a quick vid from my kodak, which isn't a real accurate sound but...

Cool! I'll bet when you hit the gas, it feels like you have square tires!

I'm sure it does, but I haven't had the pleasure of driving this car yet. They obviously drove it for quite some time after the damage occurred. the bolt heads are half gone as well.
