Golden Rod oiler and temperature changes

[WhiskeyTangoFox]

I needed a well built oiler and per advice here purchased a new golden Rod oiler and I'm running 50/50 ATF and acetone. I use/store it on my work truck and when the temperature fluctuats the can pressurizes and leaks. Anyone have any tricks to trying to avoid this?


Edit - I found a thread on a machinists forum saying the older style cans had a check valve to vent itself. The new ones don't. One person suggested drilling a hole in the can. I may have to do that but really don't want to.
