i have a 92 RS and im starting to put some money towards detailing the engine a bit, i've been looking at a bunch of different valve covers to put on (its a 305 TBI) but i noticed that the PCV valve goes into the top of the drivers side valve cover and theres a small hose that goes from the passenger side valve cover to the PCV filter in the air cleaner i believe, (i'd have to look), so the thing im confused about it every single new pair of covers i've looked at dont have those holes or openings for those 2 things..so if anyone could shed some light on this for me, i would appreciate it, Thanks

 

Most aftermarket valve covers that I have seen have a "breather" on one of them...

 

Usually they do not come with "breather" hole or oil fill holes. If they do sometimes they cost more! You just simply take a hole saw bit and a drill press and drill the hole. Usually the size of the breathers are 1 1/2". So you would get that bit. As far as the PCV, just don't put it back on the new valve covers.
