    i bought an older flc sat for a few years. has a b model in it went to full it with water, and noticed coolant was leaking out of the dipstick. it filled the pan up with coolant. i pulled the pan and it looks to me as if the leak is coming from the back of the camshaft. whenever it starts leaking it pours down every side of the block all at about the same time. is there anything else that could be causing this besides a cracked block. im thinking it may have froze at some point
