Not sure if this is in the right spot but I might as well try. I am not familiar with the ej257's breather system, can anyone help me and tell me where this is suppose to go? Thanks in advance.
The big port on each valve cover gets T'ed together to the one single one on top of the block under the manifold. NOT to be confused with the one on the back corner at the bottom of cylinder 3. That one has the PCV junction on it. The smaller port on the valve covers get T'd together to the inlet pipe. There is one hose that goes from the PCV junction to the inlet pipe as well, then the PCV valve sits on top of that and goes to the intake manifold.
Oh, I should have stated that the block will be bolted to ej20k heads (basically ej25d heads) and the heads only have one valve cover port on each head. So should this port be blocked off?
