Guys,

Just reposting this as some were having difficulty finding the old link,

Drilled and tapped to suit 1/4 NPT valve AC Part number CV726C

Apparently standard on a 1968 C*** Camaro

I have run a hose from here into the rear of the manfold vacuum fitting which is facing rearward straight out and down to the PCV.

Dutchy. Thanks for reposting. One of those tips that just gets better over time.

.

Here’s the link for the original thread where you originally submitted the process of installing the PCV valve at the rear of the block as opposed to installing it in the valley pan or a valve cover.

2DRHRDTP, nice job.  Sure wish I had seen that (or remembered seeing it) before the block was assembled.

If you were wanting to use a PCV valve designed for the 292 y-block the 64 F100 with 292 uses a similar  screw-in valve.Go to Napaonline.com for a picture!

Mark - the check valve operates in the opposite direction on the Ford parts.............so the pipe threads are on the intake side.

You want that AC type part that Dutchy has used in his post.

The '64 Ford truck part has flow "checked " from the threaded end and throttled from the "hose" end.

The AC part has flow throttled from the threaded end and "checked" from the hose end.

The check valve prevents a backfire from blowing back into the valley.

I went to NAPA online, put in 63 Chevy BelAir 409 and came up with part #CRB29255. Looks pretty close to the AC part.

I'm going to give that one a try.
