I bought a zc sohc non vtec obd0 for a replacement motor for my 1990 honda civic Ef si hatchback, put it in forgetting to change the water pump. I started the car and ran perfect beside the leaking water pump, so I went and bought a water pump for what I told the guy at oriley, I told him I needed a water pump for a 1990 honda civic Ef si. Got it home and put the new water pump on along with some gasket maker. Started the car back up an I noticed it leaking. Are the water pumps between a d16a6 obd0 non vtec motor and a obd0 non Vtec zc the same?????

 

Same.

 

Its probably the oring on the transfer pipe going into the water pump housing on the block
They should be the same pump if its the zc thats d16a6 equivalent (less the cam) should say pm6 on it somewhere there is a bunch of different zc motors
