I'm in the process of building a B20 and while prepping my B20 cover I dropped it. Big crack along the left side. It had the hole on top for the PCV valve.

So I have a B18B OBD1 cover with no hole on top and was wondering if I can just drill a hole in the same place, install the PCV and still have it work properly. Anyone done this?

why not just use the exsisting hole ?

 

As you can see there is no original hole on the B18B valve cover, hence my question.

 

i have had the same problem when replacing my valve cover for my b18b1...what i did is cut the tube short on the intake manifold and put a breather on it...if you do this, just remember to leave the little piece with grooves on the the tube or when you start your car, it will idle at 2.75-3.25...ouuch

 

no air is being pshed through that hole you want to drill...air would only besucked in from the intake manifold
