so i did a head swap successfully and turns out somewhere on the block its leaking coolants. i've checked all the hose and its fine but when the car starts coolants leak from the block and drips down to the side of the oil pan.i've also checked the intake mani and its fine as well.i cant find the problem or did i miss something?

 

did you put everything on right? how about torquing down the head to specs?
is the head cracked?

 

i did the torquing right and i've checked the head when its off, it seems clean.unless its cracked and i miss it otherwise its okay...
