I took a look at it and it seems to be the breather box ?? I have the exhaust bracket im taking off i got the buttom bolt off is there anything else i should be aware off for a d16y7?
Ps also my new breather box is plastic the one in this picture is a metal type thats rusted??.

 

check cv boot just incase, more common

 

the pcv box can be known to leak however I suggest spraying bpc around there and confirming it's the pcv box.

 

Hello all thank you i got it done actually by removing the whole air intake manifold. It was the oil chamber had the tiniest rust hole causing drips after i filled it. Got the new one going on now.. one hell of a job antiseizing everything with new belts siliconing the tubes with new clamps should never be so hard for anyone else now.
