Running with no PCV just 2 breathers...BAD??

Im not sure how all this works so I'm asking here......finally.

My PCV valve was buzzing/rattling so I gutted it removing the inner workings and put it back on....is that a no no?

and...could I just delete it all-together since I already have a breather on both valve covers? Is having two breathers AND the PCV overkill/bad in anyway?

Thanks in advance..

depends on the application.
Here's a bunch to read.

Funny...I JUST read that about a half hour ago. The engine has 600 mi. on it. Could I be creating a vac. leak/lean condition kind of situation running it like this? My idle does roam around a little, nothing too drastic.

Be gentle...I'm learning still

Shawn you ideally want a PCV on one side and a filtered breather on the other side so that air is drawn in one side to replace the blowby that is drawn down/over/up & out the other side.Blowby gasses are corrosive and impede the downward travel of the pistons. I would just replace your buzzing PCV and if your vacuum at idle requires a different PCV then yes find the correct one for your particular (I'm assuming non stock) app. A breather in each valve cover will keep the crankcase from being pressurized but will create no movement. Better yet is running a line(w the right valve) to a header collector so these gasses dont alter the precise air/fuel mixture in the carb but the blowby is still evacuated but this will greatly increase exhaust emissions

Gotcha...I'll replace the PCV valve and just replace the one breather with a "fill cap". The 340 is only slightly over stock, not a radical build at all.

Thanks for the replies fellas!!

Would having just two breathers create a lower vacuum reading situation than with having a PCV and a breather?

The PCV is a controlled vacuum lek.When you gut it its like having a vacuum line open.This has been discussed lots.We run just breathers on our motors.Mine is pretty much a race motor on the street and the kids 413 is almost 50 years old and running the OE rings.Neither has a problem without PCV.But running with a gutted PCV will make it lean.Rocky

no it wouldn't because w 2 breathers(no pcv) you'd have less flow than a pcv/breather & less flow = less vacuum. EDIT Oh you meant your eng vac reading at idle as opposed to the amt of vacuum drawn thru the crankcase? 2 breathers(& no PCV) means no (controlled) vac leak from the PCV but if your eng vac at idle is low it's pretty much unrelated to the PCV/breather system unless is is malfunctioning partly open or is too large for your app as at idle the PCV is pretty much closed which would be the same affect as you having no PCV with the 2 breathers .
