Welding plastic to be airtight

Recommended Posts

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

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".

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.

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.

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.

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.
