Stinky meth kit ?
 

I'm getting a odor coming from my meth kit,there does not appear to be any fluid leaking (I,m assuming I'm smelling a vapor ) but the stinkage is bad enough for us to smell it inside the house from the attached garage.
I recently switched from windshield fluid to a 50/50 mix of water and meth I'm not sure if there is anything I can do to alleviate this other than airing out the garage? Thoughts ?

Where is your tank? It getting heated up and pressurized while car is off and in garage?

Its right above the opening in my 99 spec front end,I was installing some mesh and got a whiff when I was fitting it.

My guess is the heat from the radiator is rising and hearing the tank up and pressurizing it. That same heat over the years causes the urethane bumpers to warp. It’s a significant amount of heat.

I could see that but there is a heathy smell and the car has not been started in 4 days.

you could always ditch the methanol and go to straight distilled water.

Regarding your last post about the vehicle not being started for several days... That would lead me to a leak as well.
Is there a pressure test you can perform to maybe see where it's leaking?
What about the cap to the reservoir? I'm not familiar with these sort of kits, but will an open container of the solution smell as strong as say a leak that persists external to the system?

Can also be from ambient temp changes in the garage.

Do a key on test and pop the hood. The pump will be running and you can track down if you have a leak somewhere.
you should be able to smell it, see it and maybe even hear it.

Do you have a filter in line? Check to see if the filter is clogged or not screwed together tightly.

Maybe I am missing something, or its a brand thing, but I run a 60/40 meth/water mix and whenever i fill up the reservoir I hardly notice any smell at all.........
