so i just did a motor swap and the car had a bad head on it so I went and got a d16y8 head and put it on the d15b7 block and got it running but it is running really rough and oil is leaking out of my headers. What would cause these problems. Oh and before hand i did a dpfi to mpfi conversion to it. Is my timing off and that's why it runs rough and the oil i have no clue on.

 

maybe bad pc valve. check and see if oil is present in air intake tube.

 

no oil in intake i checked that first. because thats what I thought at first

 

is it leaking INSIDE your header from the exhaust ports, or is it leaking ONTO the header from either the head gasket or a bad valve cover. can you post pix up?

 

its leaking into the headers and im new at this honda tech thing so I dont know how to put pix up
