1963 fi pcv
On a 1963 fuel injection engine there aren't any valve cover or oil fill tube breathers. Where does the engine get fresh air for the PCV system?

John,
Clean air comes in through the air cleaner assembly, through the air meter adapter, then through the chrome tube that connects to the oil filler tube. -
Re: 1963 fi pcv
Make sure you have the clean air tube installed. Goes from the Right bottom side of the air cleaner adapter to an J-shaped tube which plugs into the bottom of the exhaust manifold. I don't know if you can really call that clean air but that's the typical name used.Comment

Re: 1963 fi pcv
Are you trying to confuse everyone? What's that got to do with the PCV system?
And while I got ya on the fone, do you think original St Louis installed CV-590 PCV valves in 63 had the round paper tag? Or just replacement valves sold in service?Comment

Well Mikey since you are hi-jacking the post (also) I will take a stab at your good question. One that a lot of us have wondered about for an eon.
My opinion is the round paper tag (of various colors) was just sold in service.
Now what is your opinion?
Meanwhile you and John were talking about clean air. One might think a "clean air tube" would be part of the conversation don't you think.

Re: 1963 fi pcv
To paraphrase then, clean air for the PCV system comes from the air cleaner via the oil fill tube and clean air for the choke assembly comes via the J-tube at the exhaust manifold. Thanks guys.Comment

JD, while I try to never agree with anything you say in the morning before you've been to Panera for coffee, I do agree this time.Well Mikey since you are hi-jacking the post (also) I will take a stab at your good question. One that a lot of us have wondered about for an eon.

I don't know for sure on the round paper tag but I do remember changing a lot of PCV valves on nearly brand new 63 passenger cars when I was a kid working at Grampas Shell station in 1962-63. I remember that the original valves I replaced did not have a tag but all the new ones in boxes that we had did have a tag.Comment

Michael,
To add to the conversation - so the IN SERVICE valves did have the paper tag. Now were the IN SERVICE the CV-590C designation or CV-590?Rick Aleshire

Rick,
I do remember the tag on new valves in the box. I don't remember the color of the tag though.
The replacement CV 590 valves looked exactly the same as the originals that I removed, other than the tag. I never studied either closely but they did look to be the same black plated machined valve.
There was no such thing as a CV 590C in 1963. Or 1964. Jorjorian can tell us exactl when and why that was added. (he may not tell why though)

Re: 1963 fi pcv
Too bad we don't have a thread just for this subject Michael. I have gotten a few emails on the 590 and the decal. Not going to say anything else at the moment .
Basically by the time I get the FI's most of the real deal PCV valves are gone and replaced with 590C sheetmetal ones.Comment

Re: 1963 fi pcv
JD,
I thought there was another long discussion about the CV-590 PCV valve not too long ago. I think everyone finally agreed that all 63's used a CV-590, not a CV-590C.
I know there's an error in the latest 63 JG that refers to the correct valve as an AV-590 instead of a CV-590 but that may just be a typo?
Does anyone still think something other than a black machined steel CV-590 was used for any 63?Comment

Re: 1963 fi pcv
Michael, I am sure most of us know by now that the 590C was not used on a 63 and early 64.
I have a NOS one in the box. CV 590 5649689 Has a decal.
Been thinking about the decal again for the last two days. One might think I should know if the part should have a round free spinning decal or not. If I had to bet on it I would say no. But not all agree with that thought. You do but some others don't. I do know as you do also that the rectangular stick on decal my pal FI Art sold for an eon is 100% incorrect.
Meanwhile back to work. JDComment

Re: 1963 fi pcv
JD,
I just had a thought. One of the brand new 63 Impalas at the upcoming auction in Nebraska would have it's original 590 PCV valve. Maybe someone that attends the auction can take a look to see if the valve has a paper tag? I think passenger car used the same valve as Corvette?Comment

Re: 1963 fi pcv
There has not been any activity on this thread for several days, so I figure I can safely highjack it now. I chose to reply to this thread rather than starting a new thread as I have a question related to this subject.
I have a restored 63 FI unit (375). It is on a 1962 327 block. Engine is a rebuilt 870 block, hydraulic, low compression. Being a 62 I have the road draft tube (sniff tube as we used to call them back in the days). Do not have the PCV valve setup. I have been told that the vent line from the air meter to the oil fill tube can mess the FI air meter from the oil fumes. My question is this true, and if so, will it be a problem with a car that will only see 1-2k miles per year? I believe I should have more than just the road tube for engine ventilation.
Appreciate any/all advice. -Dan-Comment
