Hi, I tryed serching and looking for a solution but I cant find anything telling me exactly what to do.. I have a b18a1 block with the black box on the back of it with 2 hoses coming out. 1 going into a fitting on the back of the block and 1 going to the intake manifold.
this is where I am having the issue now.. The head Im using is from a 96+ OBD2 B20 head (& valve cover) & a OBD1 B18b intake manifold. The intake manifold does not have the PCV valve like the OBD0 should, And the valve cover has one built in. I did a search and found a post saying that when useing the b18b or B20 valve cover with the PCV valve built into it I can just run a hose to the intake manifold.. Will this relive enough pressure it needs to? does this mean I can just plug the holes on the back of the block where the old black box and fitting were? or should I plug the valve cover where the PCV valve is and use the hose from the black box to a PCV valve and from there go to the intake manifold? BTW this is a non boosted N/A motor and is in a EF chassis


also if anyone knew what throttle cable I have to use with the b18b intake manifold in a EF since the one I have now does NOT come even close to lining up. I belive a 94+ integra cable should work..

 

im interseted in your question as well..i installed a b18a1 today and the fittings were broken..i just pluged them up with flywheel bolts... is that bad for the motor???

 

doh: You can do either or even both by splitting the line coming from the IM. It doesn't matter as long as the gasses in the motor are evacuated regularly. If you are talking about the bracket mounted on the IM that holds the cable, a custom one can be easily fabricated with a flat piece of metal. If the cable's the wrong length I'm not sure which you need.

Beat: Plugging your PCV system can cause oil leaks (small usually) and trapping explosive gasses inside a hot motor can be dangerous.
