PCV Valve removal

[Bigtime]

Hello All!
I am almost embarrassed to ask this question....
I have a '65 Coronet 500....383/727. It has a light weight aftermarket cam & headers, Edelbrock TM6 [Tarantula] intake and 600 CFM Edlebrock carb [which I plan to change to a 750 CFM in the future].
I bought a vintage pair of M/T valve covers and had some very expensive ceramic coating applied to them.
Having said all of this, here is the question:
My PCV valve vents from the front of the carb to the hole in the [presently installed] Moroso valve covers.
Can I use a 1 1/2" rubber plug to plug the "twist in" breather hole on one of my M/T valve covers then drill a hole in that plug and insert a push in VENTED breather WITHOUT any engine problems?
I am trying to eliminate the PCV valve and hose for a cleaner look. Thanks!

Eliminating the PCV valve system is a really bad idea in my and others opinion.
I'm not pushing you to get the M/E Wagner PCV valve (although I have one for my 440 6bbl AND my wife's Pontiac 421 Tripower). Great information on how important a PCV system is...Read this.

I REALLY APPRECIATE your reply, and it has confirmed my suspicions. I will find a plug for the hole and drill it for the .7 [nominal] PCV valve diameter and life will go on...thanks, and if anyone else has a clever idea I am listening.

Just for clarity, I have a filtered breather to allow air in through the driver's side valve cover, and the PCV valve in the passenger side valve cover which is connected to the vacuum source of my center carb PCV connection.

Well, a PCV prevents reverse flow in case of a back fire.....and if you've never blown off your valve covers........................

Don't think eliminating a PVC is a good idea

You can eliminate the PCV as long as you replace it with a breather.

 

[PurpleBeeper]

You can eliminate the PCV as long as you replace it with a breather.

I believe you are correct BUT I think you'd need to seriously re-tune your carburetor at the very least. Personally, I would not remove the PCV.

 

[dart4forte]

Also, make sure your new valve covers have baffles.

Why would he have to retune his carb?

Change in vacuum.
I seriously encourage everyone to read the various jewels of wisdom that M/E Wagner imparts on their website, and I have read similar well written articles that I think they link to. I learned a lot after changing valve covers and the PCV valve from stock to "one that fit" and started having a number of problems that all PCV valves are not the same and there is more to the function of a PCV valve than I could have imagined.

I use breathers, no problems no need to tune carb..
PCV reintroduce oil fumes into the intake and I think it's the best octane booster...

Any street car should have a PCV to keep the motor clean.

I need to make myself get on my carbs and give Gene at M/E Wagner a call too. He and his son Matt (the engineer) are GREAT on the phone and via email with tech support, and the owners manual is EXTREMELY helpful and detailed too.
Right now both of the M/E Wagner PCV valves (one on my 440+6, one on the Pontiac 421 Tripower) are set to "fixed orifice" mode because I've never taken the time to tune them. Their PCV valve fixed the problem that only developed after I changed the stock valve covers to my beautiful krinkle black aluminum fabricated MOPAR valve covers and installed a PCV valve "that fit". All of a sudden I had oil leaks and at highway and race track operations oil spritzing/leaking out of my breather. The M/E Wagner PCV valve fixed that!
I can recommend it to EVERYONE whether or not you have any problems with the PCV valve you have now, this will take you to a higher level of performance all around!

Re-tuning would be necessary when eliminating the pcv. You have to cap the vacuum port on the carb, which would be the same as plugging the pcv valve...(take it out of the valve cover when idling, plug the valve with your finger and watch what happens..engine will die unless there's another vacuum leak somewhere)

I will have the same set up. Thanks.

 

[Ranger16]

That's exactly how mine is set up.

Very interesting read, now I am wondering if my generic PCV valve isn't really doing as good of a job as it should, and may explain some of my carburetor issues with my stock setup and the fact that I have a bigger cam installed and different compression, wonder if one of these is really worth the price. Who else uses one of these tunable PCV valves???

Every time I've gotten close to shelling out to try one, something else happens and the funds get redirected. Last time it was because my fan ate my radiator..
