You need to check this on your car

The vacuum check valve is a likely source for a vacuum leak.  I have noticed several leaking at the assembly joint on the bottom.

I have fixed several by running a bead of super glue along the seam.  If you don't have one, or your is broken, its easy to make your own. Get a vacuum check valve at your local parts store.  Splice it into a T fitting.   How easy was that!

Tring to figure out my vac lines on a 63 Deville. I'm looking for the location of the source vacuum to   this check valve, Mine is disconnected, thanks for any help.....

Hmm, I remembered wrong. I did not buy the vacuum valve. Russ did and sent it together with some other parts I needed. My memory is like the gold fish...

So if your valve is not working properly. Just buy a new vacuum check valve (from Russ) and install it as per above. Nobody will see the extra valve. Cheapest and easiest solution.

There are no new original vacuum valves available. I have been in contact with Bendix and they say they don't have any. And the molds are gone so there will not be any new manufactured.

The only solution is to use Russ plan. It can be done in many ways and I did my own solution. Basically i bought a 5 USD (in Sweden it was 10 USD) and fitted it above the original. Used the same hoses. As the original is now working as a t-piece in the correct position all is perfect and not visible.

Jason or Russ,

I would like to keep mine stock if possible but I cannot find one that works.  Do either of you have one in your parts for sale?  I tried the super glue fix like Russ suggested might work, but no luck with that fix.

Temperature gauge not working properly

Posted by SK on March 23, 2022 at 2:43pm 2 Comments

The temperature gauge of my 63 Eldorado does not work properly.

It goes slowly all the way up and stays there, while the true temperature is around 155-160 F (water in the radiator and/or the top of the thermostat housing).

Where should I start to solve the problem? The gauge itself, the temperature sensor, or the wiring? Or something else? The sensor is a new (aftermarket part)…
