420A Valve Cover Breather

[PhilipMc]

I was just wondering if you can put a valve cover breather on a 420a engine? And if so where would it go, and how much hp does it add?

No horsepower gain, but it goes where the line that runs to the intake would normally be (back driver's side of the VC).

 

[PhilipMc]

The one that goes into the intake piping? And whats a "VC"?

Best thing you N/T guys can do if you do have oil in your intake pipe, is to put an oil catch can inline between the VC (valvecover) and intake pipe.

I don't have oil in the intake pipe, I was just looking for a couple of ways to boost some hp before I turbocharge my car. Like once I have the money to turbo it. But thanks for the advice.

You actually already have a couple of breather's on your VC (valve cover). The one that goes to the PCV valve and the one that's located on the back side of the valve cover (that goes to the intake pipe). You gain no HP by making these bigger (or sending it to a catch can).

If you were highly modified with a 8k redline, you may gain a few ponies by releasing crankcase pressure at higher rpm's.
