Quote: Where did "we" learn this propane / acet "trick?" Is this being taught in some mechanics school? Is it in some manual / book you bought? I've never heard of this before, but as a guy who used to service HVAC, including nat gas/ LP/ oil heat, I'll guarantee you that if you do this enough, you'll regret it.
Better step back on your rant. Propane was once used to set carbs up. It was an authorized mopar service procedure. Properly used I see no problem un using it for a vacuum leak. A running motor is going to burn it not deposit it in the crankcase. There is a lot you obviously do not know.
I'm not stepping back from anything, and this is not a rant. It is a statement of FACTS that HAPPENED. I'm well aware of the propane setup procedure, and it has nothing at all to do with injecting flammable materials into the crankcase, any more than running an engine on LP does.
What I asked you is, where did you "learn" this, and so far you have not given a factual answer. I'd be willing to bet you cannot quote ANY respected shop manuals, school texts, or any other respected source that recommends this.
I WILL GUARANTEE YOU that if you do this enough, there will be an unplanned event. You will not like the unplanned event.
