i just put on a gsr head on to my b16b block and when i fill up the radiator water comes out of my oil pan with the drain plug off

what did i do wrong with the block swap /???

please help

the block is a JDM b16b and the head is a usdm GSR

could i have hooked up some hoses wrong ???

i noticed the the jdm block has a oil filter cooller and my usdm gsr block does not
would that make any difference??

 

sounds like you forgot to put the head gasket on. retrace your steps. how did u install the head?

 

i fallowed my helms manuel

i tried filling the water in through the filler neck on the head with a hose and it goes straight out the oil pan
