Can not stop oil from leaking.

Well, it sounds like either the TQ or possibly the flex-plate may be cracked. IDK 100%. It is making a light knocking sound that is coming from the TQ. I have the car in the air and crawled under to listen. My car has a GM 700 R4 trans with a Wilcap adaptor plate and flex-plate. I moved from the oil pan to the TQ and its louder at the TQ. It just started this two days ago.
