Default PCV conversion kit Install Issues

Installing a major vendor supplied PCV conversion kit on my 62 this morning. But, as the photo shows, the carburetor stud will be in the way. I suppose I could use a shorter carb stud and tilt the adapter up maybe 15 degrees, but it will still be a tight fit. I can't believe this is the way its supposed to fit?

My other option might be to see if ACE carries a brass threaded nipple and union to go between the adapter and the carburetor, to space it further out from the carb.

I'm not the 1st guy doing this and its not rocket science, but would like to have a good installation and not a bubba job.

Thanks!

Butch

Try a 45 degree elbow. It’ll give a better angle.

Yep, that might be the best option and thank you Dan. Although the 45 might solve the issue, why does this kit come with a 90 degree adapter that won't work.


Also, that would be assuming the threaded portion on the hose is the same as a brass fitting.

Not sure what kit you bought but the 90 would work with the WCFB.

Butch - According to the AIM, the 90° fitting is suppose to be rotated up 45° so the hose clears the stud. That might not look very good but that's what the factory did.

Hope this helps.

They only offer one kit and it was advertised for a 1962. But, if you look at the stud placement on your WCFB's, they are different than on the single AFB. Your studs are inline with the main body and on the 3269S AFB, the carburetor has mounting ears that are outside the main body. I'll get it to work, was just surprised a kit made to fit a 62, doesn't do what it's advertised to do...I guess I shouldn't be, considering other issues I've run across.

Number of things you can do.
-You can just get straight fitting,a nd come straight out the back.
-Get an extension piece and move the 90 further back.
-Get a 45 as suggested.
-Move the 90 upwards to clear the stud.
-Install shorter stud.
-Get a screw in PCV valve and dump the fitting entirely
Etc.

Thanks Doug. Yep, heading to ACE in a moment and believe the extension is my choice.

Turned out to be an easy fix. Not a fuel or water line and not under pressure. Thanks for all the suggestions.

Looks good. Don't forget the vacuum line or plug on your hollow stud.

Not to be critical, but with that extension your PCV and hose are a lot further outboard than typical. Maybe you could try a set-up like this, using a Tee with FM 1/4 pipe threads. I added a bushing where it goes into the rear of the carb to move it out. The 1/4" hose fitting is for a vacuum gauge I'm using, so it could either be plugged or used if you had power brakes.

Don't be confused by the fuel filter location. The carb I'm using has a rear fuel inlet and it's plumbed correctly for the application.

Glad it worked out. My vote would have been to replace those long, long studs with stock carb studs, or even use a bolt on the one flange instead of a stud. Those are about the longest carb studs I've ever seen!

Yes, I thought so too. I just wanted to get it back together and check it out for leaks, but shorter studs are on the "do" list. The close nipple only put the PCV line out another 1/2" and doesn't interfere with anything........so far.

Thanks rsavage1. That's where the W/S washer hose plugs into vacuum and pretty hard to forget since it's right up front. I've forgotten other hidden items before.

If you eliminated the road draft tube you'll want a 63 spark plug loom to attach to the RH bellhousing if you haven't already done it otherwise your plug wires will be flopping around *****-nilly..

Yes Sir! Glad to see you're like most of us and have memory lapses. You sent me the link for the part at Paragon and it came in on Friday. Didn't know where it attached, but now I do. Trust me Frankie.......your help is greatly appreciated by many of us here on the forum.

Seems I always learn after I've done it or by mistake. Until I saw W Guy's post, I didn't know that hose comes off the PCV module, thought it was built as an assy. I was moving the hose around to put the wing nut back on the upright ignition shield and the hose popped off the valve. Wow! I could have (and will sometime) just route the hose directly into the back of the carb from the block plug and avoid bending the hose around the everything.....duh.
