Camaro Proportioning Valve Autopsy

Nice breakdown of the valve. I wish you would consider calling the valve "pressure regulating valve". It might go a long way in educating people on the correct name of both the round hold off valve and the frame mounted pressure valve.
I have had both valves apart before during restoration work. Fortunately I was able to clean and re use all the cup seals. The o ring gaskets are easy to find.
I think there is a need and a market for a correct and functional seal kit for both the Hold off valve and the Pressure regulating valve. I would bet some of the Camaro parts place's would like to offer them. You might even just offer them on ebay with a BIN price ? I think photos of the valve apart also would go along way in selling a kit.
I would gladly pay $30.00 or more for kits that are complete and correct.
Are you doing a breakdown of the round Hold off valve also ?
Great work and thanks for sharing.

I used both terms in my autopsy and new rebuild articles. I'm hoping that by using &quot;proportioning&quot; in the titles people will see which of the valves is really the proportioning valve. Here's a link to the rebuild article:

They're easy to find in the wrong material. The common Nitrile/Buna-N o-rings that you can get at your local auto parts stores are NOT compatible with glycol-based brake fluid. DOT-5 silicone-based fluid is a little different, but since EPDM rubber is compatible with both types it's what I use in my seal kits.

Thanks for the feedback, Mike. If I can get my hands on a metering/hold-off valve to take apart I'll see what I can do.

I just added a seal kit to the products I'm selling on my site. I'll post a link in the &quot;parts for sale&quot; forum. I think you'll like the price.
