PCV Hose routing for 63 F.I.

[Tom R.]

Would someone please post a picture of exactly how the hose from the Plenum gets to the tube coming out of the breather tube. Outside or inside of the coil? Mine is presently on the outside of the coil and the hose I just ordered is waaaay too short to reach. Thx.

Tom, I can't answer your question but would like to add to it. I would like a picture of the "plug" in the back of the block and pipe that comes out of it. I cannot find this part advertised new so used must be the only offering. Thanks, Don H.

Re: PCV Hose routing for 63 F.I.

Same experience with the too short hose, don't recall which vendor. Went to parts store for hose, Should be enough photos to illustrate correct routing. Without looking, I think the hose takes the long route. Getting it to stay perfectly in the back of the block is an other story with either the early or late plug.

Re: PCV Hose routing for 63 F.I.

The original hose has a small diamond pattern to it. Not available at any auto store today.
Here is something I learned from restoring a ton of 63 FI's over the years.,
The 90 degree fitting should be almost verticle when installed. At best maybe the fitting could be turned a degree or so toward the firewall.
If you don't get the angle of this fitting correctly then the hose just will not fit properly with the vacuum line coming out of the back of the block.
As far as being concerned as to whether a repro hose is too short or not the correct length I would say that is not a big deal. It's not the correct hose anyhow.
Tip: Go to your local auto store and check in their back room for old fuel line hose. Some of the old Gates hose has a diamond pattern to it. Now this pattern is not quite the same as the real deal but it's decent. JD

Look at www.licorvette.com is part 22-11AE or 22-11AL what you need?

Re: PCV Hose routing for 63 F.I.

Harry, 22AE is a part used until May 63 according to LI. Comprised of a sleeve and a hard rubber grommet.
Original rubber grommets (with a hole in the center) have the logos: GM and opposite of GM = R 52.
This sleeve assembly was used on other Chevy blocks of that area. Most of the time when an engine is rebuilt the sleeve and grommet assembly get destroyed.
Typical replacements are the usual one piece rubber grommet that pushes into the back of the block.
Most of the restored 63 engines I look at are missing the proper sleeve and grommet assembly and just have the SR grommet.
LI has a nice one in their catalog as you mentioned.
Getting the proper 63 PCV valve parts installed is not as easy as it sounds if you want to do the job as original.
Also we still go back and forth today as what the plating or finish should be on the PCV 45 degree fitting. Once again Michael Hanson has put up numerous pics showing that brand new 63's he took photos of showed this 45 fitting with a zincad plating. Although I have seen some that are blackened I do believe that the majority of the 63's had this fitting plated with zincad.
So you have the plated fitting, the proper 590 pcv valve, the diamond pattern hose, the vacuum tube-don't know if Jorjorian said the tube was bare or cad plated, and the adapter grommet/sleeve assembly up to around May of 63.

Tom,

Here's a pic of an unrestored 63 that shows the correct routing of the tube and hose. It's the black/saddle Z06 conv. (could be John Hinckley's picture? can't remember)

Tom,

Thanks for all the replies. Mike, that's it!! I have the exact same pre-bent tube with the little flip at the end but mine is behind the coil, closer to the firewall, and then I have a long hose that connects from behind and around the outside of the coil to the PCV valve. Now I see what it's supposed to look like. John, I'm going to look for some of that hose with the diamond pattern in it. I know what it looks like. There's an old auto parts house still around I used to go in Whittier years ago and the guys will let me roam through the back.

I can't thank you all enough. That is an awesome picture of an untouched 63 FI engine bay. I'm saving that for reference. You guys are great.

Is this the diamond textured hose to which you referred. Got this from Autozone. After the short hose came from the vendor I just want to get it togethher and run it.

Michael;

The picture you posted of the original 63 shows a pipe in the position which I believe is identical to that used on my L-76 (340 hp). Even the hose looks about the same length except it bends upward instead of inward. I suspect the same part numbers are used.

Thanks Stu.....

Yes, the position/routing of the crankcase tube would be the same on all 63 engines. Between the distributor and coil. Not on the outboard side of the coil.

Joe,

Here's a picture of what appears to be an original PCV hose with the "quilted" texture. (the paper label/band on the valve is incorrect though)

I have an NOS hose here somewhere and if I can fine it, I'll try to get a much better closeup shot or scan.

Re: PCV Hose routing for 63 F.I.

Joe M.;

Suggest you take a close look at Michael's pictures if you really want to do it right - both hose material and routing, etc.

That pattern hose is exactly the same as I have had on mine for as long as I can remember. May even be the original one.

I bought two (2) tubes long ago; one is cad plated I believe which I use strickly to improve the appearance, and the other is a satin black finish (my original was a little corroded). Was there a black finished tube (pipe) used on the standard 250hp or the 300 hp? Otherwise, I can't recall where or how I came about having that one.

Michael, Nice pic of the hose. See what happens when the 45 degree fitting is turned too sharp toward the firewall. Puts a kink in the hose and causes misalignment. John

Hey Jorjorian, Tell us how many diamonds to the inch on the real deal hose. Or your imput on real deal hose.
Thanks, JD
