Not knowing what year, make, model and engine you have I can only guess that you may have a rotted out welsh plug on the back of the engine block.
sounds like the head is cracked.
The Ford 302 engine will not bolt to the 300 six-cylinder bell housing. A new bell housing or a Bell housing modification kit will need to be used.
What it sounds like to me would be a rear main seal. Oil might be leaking into the transmission bell housing and when the car is reversed the momentum is dumping what the bell housing caught.
Depends.if the bell ( where it covers the flywheel behind the motor) is a bog block.or small block bell housing. Like a small bell housing will bolt to a 302 and big bell.housing will bolt to.a 460
No it is not. The diesel bell housing is much larger.
No.
No.
No it won't the 360 has an almost perfectly round bell housing ..and the 300 6 is the small block bell housing which has the top two bolt holes higher so it will not line up
I can't find a reference for the 902. The 904 will bolt up only if it has the correct bell housing on it
No. the bolt pattern is different.
Yes, it has the same bell housing bolt pattern.
No.
