Breathers
With an FE engine you can't have enough.
I disagree with Bill, here's why. He's an engine builder who dosn't want you whining about oil leaks. So stick a PCV Valve in and create negative crankcase pressure, no rear seal leak or other pesky leaks at least for 1 year until the warranty is up.
Now what is happening, the PCV Valve is in an unbaffled valve cover and it's sucking with engine vaccum and guess what, that's where your oil is going along with the crankcase emmisions. Your intake valves are going to be all gooked up with oil. The rear intake placement of the PCV is much better with the original style breather basket, or a valve cover that has baffels made for a PCV valve such as Blue Thunders, and others.
I don't run a PCV Valve so I am not sucking any junk up in my engine but I am running 4 breathers to get the air to the engine crankcase. Look at the old pictures of FE Racing engines, that had all kind of breathers and no PCV valves. And I am not saying PCV valves are all bad they accomplish negative crankcase pressures, some placements of them suck, such as unbaffled valve covers.
Thats my 2 cents worth.
