Well I decided to take off the clutch cover and see if I could see anything in there. I found the cracked bell housing. Could I have broken that when I changed the motor mounts? How would that crack? Now I'm looking for a bell housing!
Well I got the bell housing off and it looks to me like the block is cracked. The flywheel was cracked 3/4 of the way around. Only 1/4 was not cracked. The pic is of the oil pan and flywheel. I know it has been there for years but I don't remember it being that big. I wasn't looking for a problem so I never thought twice about it. May have had my last ride in the car. Drove it for 54 years.
Call Fort Wane Clutch.
You have a 215 six cylinder engine yes?
Are you sure that's not just how the rear main cap loops on that engine?
I think 38 coupe is right, I looked in the parts book and the main cap is part of the pan rail on the 215.
