PCV valve location
I believe that I already know the answer to this dumb question, but does it matter which valve cover the PCV is on and which valve cover the breather is on? I want to swap the two for aesthetics.
|
As no one else is rushing to offer an answer, I'll offer my opinion. I can't see why it would make any difference whether the valve or breather was on one side or the other.
|
Are you talking about front vs back of the same side or left vs right? If left vs right it does matter and they cannot be swapped. See the discussions about oil catch cans for the reason.

I think maybe
Maybe because usually the oil fill is on the drivers side? Also does the way the rotating bits throw oil, is there more oil ‘fog?’ On one side that the other? You would want the pcv on the ‘dryer’ side right?
In short i have no idea, mine is on the passenger side… Merry Christmas 21 Steve H Spf 1764 |

Then why did Ford put the pcv on the driver's side in the 1978 Bronco?

On my 427 Windsor, I did not have PCV vented into the 8-stack. Instead I had some K&N filters... One side (the side that all others have the PCV) the filter always had some oil on it. Had to clean it "frequently" (not because I thought it was clogged but because it attracted dust). The other side was always dry as a bone. Which side - I honestly don't remember. The purpose of the PCV is to recapture those vapors. Why the engine works that way was explained in one of the catch can topics. I think it has to do with crank rotation direction? By the way, how do people that have 8-stacks connect a PCV??? When I registered mine I thought CO was going to make me have one but they didn't and I didn't ask. |

First, I've not heard of the crankcase pressure being higher on one side of the engine than the other, and it doesn't sound right to me. Second, I looked at a few old threads re "catch can" and didn't see anything about crankcase pressure. So I'd like to see a link to the discussion that does. Third, I did find a discussion that suggested that the right side valve cover would have a higher oil level (and thus more oil droplets in the vapor) in race cars driven by high level drivers on a counter-clockwise course. That is because the G forces would pull oil toward the outside during the mostly left hand turns. As the OP is not likely to fall into this category of user, I stand by my earlier opinion that it doesn't much matter which valve covers has the PCV connection and which has the breather.
