I'm replacing the evaporator core on a 1967 Camaro. There is some "goop" wrapped around the top tube of the evaporator core just where it goes into the case. It appears to seal a probe against the tube. What is the "goop" and where can I get some more?
The attached photo shows the sealant just as I was opening it up. Fortunately it was triple digits in the garage so the goop was pretty soft and easy to pry open.
Also, does anyone know if the sealant that goes around the perimeter of the evaporator case (against the firewall) is sold anywhere? It had the consistency of silly putty (was still pliable) and seemed to have a nylon thread running thru the center.
I also found some strange stenciling on the firewall covered up by the evaporator case. I'll try to post some photos of that also.
