Look closer at the check valve.. Hint, hint..

What moron would spend $140 to put a 50 year old check valve on their car? Especially when the REPOPS are new, correct and only 10 bucks!

You'll also notice that Chuck doesn't say it works. Just that it's "in nice original condition".

That is not an OE check valve, those are common as dirt and not even worth shipping, and I suspect he knows it to. It is called a fishing expedition.

If that is the case then No its called dirty.. But as the old saying goes.. Buyer beware..

Oops. I didn't even look closely at the valve itself, but yes, that's the 70's version!

Wow! As Mike said common as dirt as that is what they put in every booster you have restored, etc. And yes, he knows it!
This is a real correct one on our 68Z and what it should look like! Hopefully these pictures will assist someone's future purchase.

Thanks for your keen sense and great knowledge Darrell! Many would not have noticed. You are an asset to the hobby.

I just noticed I put the wrong link in my reply above. It SHOULDN'T be going to Classic Muscle, but to ZIP Corvette instead. Here's the CORRECT LINK (Their P/N DB-386), and a picture of the valve is below.

HOWEVER, note that I got this information from a thread on the NCRS site that's 3 years old, so I'm not sure if ZIP still sells that same valve (not only that, but the price has doubled since 2013). They don't show a picture of the front of it on their web site so I can't tell if it's the same one mentioned in the NCRS thread.

If anyone lives near ZIP, can you stop by and check it out?

Hey guys,
Just want to say no relation. (name), I think he has been banned from some forums. It is a shame not just this hobby but everywhere there are scam guys. Experience and this forum helps a lot.

Thanks to everyone who pointed out the differences in the check valves! I had not noticed those differences previously, but after this thread, I went and looked at the 'new one' installed by Grigori when he rebuilt my booster, and compared it to my original (which Grigori returned to me), and of course, they are like the original (and replacements) as pointed out in this thread.

Should I remove the replacement and install the original valve in my rebuilt booster? OR purchase a 'better repro' from somewhere to replace the incorrect one??

Kelley: Some may have wondered if you were the 'King'...

so it is/was a good idea to clarify that!

bertfam · « **Reply #15 on:** October 21, 2016, 03:09:10 PM »

Gary, you have a few options.

1. If you don't have your car judged, leave it "as-is". No one would probably even notice! (Unless it bugs you, then see 2 and 3 below!)
2. If you DO have your car judged, then you can leave the incorrect one on for driving and then install the original for judging only.
3. You can buy a "correct" repop from ZIP, but like I said above, you might want to have someone check it out first. It may have changed in the 3 years since the NCRS thread.

Thanks Ed,

I've never had this car judged (it hasn't been driven or left my garage since 1980), but I do have a *goal* to get it reassembled one day (with all subsystems working again) and have it judged in a 'Preservation class', so you gave me a couple of good options..

Hi Gary! I purchased one of the more correct repro's and that one looked the part but was white instead of a more vanilla cream looking color that all of the originals had, but it was not thru Zip. With our L78 Nova survivor an original valve is in and it still works. I'd check the original to make sure the check valve is working (normally they do), put it in and forget about it. I actually found them rascals can be a pain to remove due to the design (fish hook kind of style) that assists with sealing but difficult to pull out. Easy to push in though! We have originals in all of our stuff other than the aforementioned repro. I will say this, nice originals can be difficult to find so if you come across one for a spare grab it.

For a cheaper alternative to the ZIP-sourced check valve, read this: http://www.camaros.org/forum/index.php?topic=14483

janobyte · « **Reply #19 on:** October 21, 2016, 10:50:59 PM »

Perhaps the "vanilla cream" due to dis-colorization secondary to under hood temperature and age ?

Jerry supplied a " correct" looking valve when he did my booster. I never remember re-placing mine, but doesn't look right. None the less, boxed up.

Relevant to one of your current posts Gary, Steve has my hold off valve at this moment,sort of trying to talk me into having my booster re-done...but I was pleased with CHP's work.

bertfam · « **Reply #20 on:** October 21, 2016, 11:07:00 PM »

I would agree that the originals would have been white and after many years they turn cream colored.

And HERE'S a direct link to the valve Tim posted.

That vendor said the application is 67-81. That may be true as far as fit&function, but I would like to know what years used that vendor's design, or appearance, of this valve? And I know this is not an exclusive Camaro part.

Well, it's hard to narrow it down completely, but according to the P&A's, here's what they looked like, and the (approx) years and part numbers used.

I respectfully disagree on that as the one I posted was a NOS piece on a May 1968 unit purchased from Stahl Headers when they went out of business. The unit had never been installed so that is what the color looked like. Every unit I've ever looked at was a cream looking color and never white. If they went from white to cream color over time they sure were similar...... I'm confident from what I've reviewed this is how they looked new back then.

This was the Engineering Change Sheet with the unit I purchased.

That picture is my picture I posted on my build thread. The reason the correct one (middle) looks more white in the middle area is I tried to lightly sand it and it took the coating off and the base material is white looking. That is why I wanted a NOS one and still have all three of those Ed posted.
This is my picture I posted!

ko-lek-tor · « **Reply #25 on:** October 22, 2016, 02:10:37 AM »

And a great pic it is Chick. Thanks Ed for assigning dates to that pic. I only have had used junk, but have never seen any color except the off white as pictured. I do know the valves for 64-71 (middle one pictured) have a tendency to deteriorate and get a chalky white appearance and that nice examples I have seen go for prices elsewhere on the net similar to like what was asked in the OP, but not for THAT one, of course.

69Z28-RS · « **Reply #26 on:** October 22, 2016, 03:35:15 AM »

Shown in the photos below are:

1) The check valve installed by Steve Grigori when he rebuilt my booster,
2) View 1 of my original check valve returned to me when he rebuilt the unit
3) View 2 of my original check valve as returned to me

Some *idiot* (probably me?) had spray bombed my booster back in the '70's, so there was black overspray on the original which I attempted to clean off today before the photo. One can see from the protected portion (that went into the booster) that the proper color is 'cream'.

bertfam · « **Reply #27 on:** October 22, 2016, 03:03:31 PM »

I will concede that they probably weren't "WHITE WHITE" from the factory, but more of an "off-white". But after 50 years, plastic has a tendency to yellow. I don't believe they were originally as yellow as what we're seeing now though. I believe they were originally more of an "egg-shell" white.

And yes Chick, I stole your picture because it was a greeat example of all three versions in a row!!

Ed, you did not steal the picture but rather used it for enhancement!

I got gobs of pics from others also so no issue but I wanted to communicate that to explain why the middle one looked white. The one I showed in the aforementioned picture is in reality a NOS valve as the power booster/master cylinder assembly (again May68 dated Engineering tag) was never on a car. The color of that valve is fairly close to even ones on survivors but this is the kicker in my view, I have reviewed several original valves and of those have not noted much if any difference in color from what portion was in the power booster or the portion stuck in the hose. No reason to debate amount of cream color and I won't but wanted to help to clarify the refrigerator white valves are just correct in color but for sure my choice over what we find in repro power boosters or what is put in when restored.
By the way, I saved your enhancement for future use. LOL
