PCV setup

[73-se]

Hello all,

My 400 has a breather instead of a pcv setup. I've searched these forums and what I've read leads me to believe I should put the pcv valve back on. My understanding is that this can be fed directly into the carb? Also, I'm having difficulty finding a valve that fits. The valve covers on the car are chrome, so probably not factory, and the hole is pretty large. There is a gasket that fits the breather in there, but all the pcv valves I can find are too small even with the gasket, and I can't find a gasket that makes up the difference. Is there something I'm missing? Or is there a special gasket I should have? Part No.s would be helpful, along with suggestions. It seems like it should be pretty straightforward but I get stumped easy I guess   Thanks for your help!

I have mine hooked in the back of my intake

The suction side is at the intake.

I would think, that there would be a rubber grommet like on a stock valve cover for the pcv to plug into. If there is not. you can get one at a parts store where you got your pcv.

If this doesn't make any sense or I'm not understanding your problem, some pics of your set up would help.

Does the engine have breathers on both valvecovers ? I've run then with 2 breathers many times w/o issue.

Yes, its running breathers on both sides. Sorry if I wasn't very clear in my explanation.  I'm a little concerned after reading that the pcv is beneficial to valve seating, etc., particularly because this engine was recently rebuilt. I'd hate to damage the top end because it wasn't set up proper... or have my car impounded by an overzealous smog cop 

The problem I've run into is that the hole on the valve cover is about 1" maybe a little more, and all the pcv valves i can find are no bigger than 3/8". I just can't find a grommet that will make up the difference. should i plug the pcv into a breather, as a stepdown?  The passenger side is the correct side, right? LOL

do you have pictures of your valve covers?  are they the stock covers?  if they are, I can provide you with the part number for the correct PCV grommet.

Not saying they are but I've seen quite a few el-cheapo chrome valve covers where finding the correct grommet for the PCV is a pain, post a pic or 2 and lets have a look.

Sounds like aftermarket valve covers that don't use a PCV, just breathers.

I think we have a winner... well, two anyway. El Cheapo aftermarket... yep. Just breathers, probably. That would explain the sizing on these things. Guess I'll have to live with it for a while because I don't have the money to replace the valve covers right now. Thanks for your help figuring out this enigma
