Shakadula Posted September 2, 2015 Share Posted September 2, 2015 Hi all, I broke the vacuum valve on my heater assembly box in the engine bay. Broke right in half when I smacked it with the exhaust manifold when I put the engine back in the car. My question is can I glue or weld this unit to be airtight so I can once again operate my heater? All suggestions are appreciated. I have attached two pictures illustrating the 2 halves. Thanks Link to comment Share on other sites More sharing options...
Leif Holmberg Posted September 2, 2015 Share Posted September 2, 2015 (edited) If it`s aluminum and you will glue it ,be sure to use "epoxy" made to be used on aluminum.Sorry didn;´saw it was "plastic".Leif in Sweden Edited September 3, 2015 by Leif Holmberg (see edit history) Link to comment Share on other sites More sharing options...
Shakadula Posted September 2, 2015 Author Share Posted September 2, 2015 I just had a crazy idea. How about a gasket maker like permatex?. It is working great on my timing cover. Thoughts? Link to comment Share on other sites More sharing options...
Smartin Posted September 3, 2015 Share Posted September 3, 2015 Epoxy would be best to fix this. Link to comment Share on other sites More sharing options...
FLYER15015 Posted September 3, 2015 Share Posted September 3, 2015 Shak,You can "weld" that plastic with a soldering iron, but it is going to look real ugly, and I would cover it up with black silicone afterward.Mike in Colorado Link to comment Share on other sites More sharing options...
JohnD1956 Posted September 3, 2015 Share Posted September 3, 2015 Probably best to replace it. Link to comment Share on other sites More sharing options...
72gs455 Posted September 3, 2015 Share Posted September 3, 2015 (edited) there is a liquid that is used in model building, not the old fashioned air plane glue. this stuff melts the plastic a little then it hardens up in seconds..." plasti weld" check hobby stores try an hidden spot.

Joseph P. Indusi Posted September 3, 2015 Share Posted September 3, 2015 JB Weld it! If it leaks after JB Weld, use black silicone to seal it. Perhaps you can find a used or NOS.Good luck.Joe, BCA 33493 1 Link to comment Share on other sites More sharing options...
Shakadula Posted September 3, 2015 Author Share Posted September 3, 2015 Thanks everyone. I agree it would be best to just replace it. I was looking for the cheap way out so i will try the epoxy with a sealent or JB weld as I have both. If that doesn't work then I will just freeze cause I need a $500 timing cover. Mine is a bit warped and I don't know how long it will last. Thanks again for all of the suggestions. Link to comment Share on other sites More sharing options...
