It sure is good to have someone finally dive in and explore the failure and share their findings with us.

The relief port shown in the DSC08042 image, above, sure doesn't look like what came out of any of the Treadle Vac units that I've ever had apart. Keith's description sounds more like it.

Yet, the replacement valve that came in the kits, back then, appeared of identical design to the original part. Perhaps that's why I never experienced a failure in any of the four running packards that have been in my family.

I've always been more concerned wirh the compensator port valve spring, but with all the talk lately of failures involvng recently rebuilt units, it's starting to sound like a problem with the rebuilder's replacement parts. Glad I rebuilt my own units when I did.

Also the cover hasket in the kits I've used was composition cork, not black paper.

If anyone has purchased a new BTV rebuild kit elsewhere, lately, it would be helpful to have a pic of the contents.
