I keep having oil leaking and never could find where it was coming from. After removing the intake. There is a hole in the engine block where the motor and transmision go together on the top side. What supose to got there a breather cap, plug or what? The oil is runing down the transmision and some on the oil pan.

 

are you talking about the PCV hole?

 

It looks like where a freeze plug would go but oil is coming out of it not antifreeze. It's about 1 1/2 - 2" perfect hole. It would be in the back of the engine block behind the firewall. Right above where the transmision and block bolt together.
