Backstory:

I have been using propane insanely fast on my 22R. At first i chipped it up to being because of the 36s, 4.10 gears, and the spins around the neighborhood. Up until last night that is...

After an evening wheeling session in my rocks, i noticed a liquid dripping from my inner fenders. I had almost flopped over, so again...i assumed it was something because of that. Until i popped the hood.

The liquid was rapidly dripping from my propane mixer. Im assuming its Liquid Propane. Doesn't smell like anything, but Im not sure if LP does. It was pretty warm, so again (im assuming) i think that this means it was doing SOMETHING inside the mixer before it was released.

Anyone have any ideas what is going on, why its happening, and what i should do in an attempt to troubleshoot this more?

Ill get part numbers and pictures when i get home.
 
LP toyota

U DENIFENLY need to fix it before U run it again--------------- A tank on my Truck (22r) also will last A good day of wheelen-
Have u checked the line goning into the Mixer-----or is it coming out of the Mixer

U should have NO Leaks even if u Do turn it UPSIDE DOWN
 
I know that it shouldnt leak. I didnt know it was propane at first...thats why i assumed it was just water from my overflow or something. I know that it should last a while. I burned about a half a bottle in maybe a few hours run time (if that).
 
Propaine

Be carefull not to get it on u------------ It will BURN u as bad as a Heat Burn-------U may have a bad Mixer-------------- where did U get It
 
If you have liquid propane at the Mixer it shouldn't be. The converter before the mixer converts it from liquid to a gas. Thats why you only have to have a low pressure vapor hose from the converter to the mixer.
Liquid propane should be cold, so cold it will burn you.
If it's hot, hmmm maybe something broke in the converter allowing coolant into your mixer??
Other than that I ain't sure. That's a new one on me.
 
OK...i think im halfway idiot. I think its water/coolant that is leaking out.

There are two cylinders on the "setup".

The first one, where the LP actually goes into. Thats not leaking.

The second piece. Where water goes in and out. Its leaking from the non motor end. The end that goes into the firewall (and goes im guessing to the back of the motor somewhere) is the end thats leaking at the cylinder. It seems to be leaking at the threads/around them or below them where the cylinder breaks in half and has a gasket (bad gasket?).

Could this be a source of my seemingly hot running motor too?
 
The heater hose is usually hooked through the converter, used to keep the converter from freezing up since LP is so cold. Leaking coolant system = hot running motor!

I think you are looking and thinking in the right direction. The Converter or as you said the second cylinder thing that has the water hoses, has to be sealed. As John said it has to have the coolant to keep it from freezing up. It circulates around the inside of the converter. If you have a bad gasket and it's leaking, then I could see where you could use a lot more pane, and also be the reason your engine is running hot.
 
Doesn't propane have to be under pressure to remain a liquid? Once the pressure is released it becomes a gas so I'd think you could never touch liquid propane.

Ding! winnah.. It boils around -40°
 
Kevin,
Pane is normally a gas at atmospheric temperature and pressure. Its stored as a liquid to minimize the volume requirements. The expansion valve (or regulator, I don't have the right terminology cuz I don't have pane) and converter vaporize it so it will burn. The converter is a heat exchanger using engine coolant to vaporize the pane, this is the critical part, .......at a rate suitable to support your motor Hp requirements (you hope). Liquid pane does not combust (it will burn though). Just like gas and diesel has to get atomized to mix with the oxygen, pane has to be a vapor. Sounds like he has a coolant leak a the converter.
