I want to be 110% sure will the baby oil contaminate the gasoline and make it not ignite properly ???
Can I use heater core plug to heat the mineral oil?
How to build it from the start..
can i use glow plug instead of soldering iron ?
The only issue I have with mineral oil as a "smoke fuel" is not knowing how it will affect various sensors after coating them with that smoke. I like the idea of a fog machine, as it is water-based which is harmless as long as you're not going crazy on the smoke: just enough to get it done.
I have diy smoke machine, and it works fine. I'd like to be sure I understand the process –
Car off
Throttle plate open (a little? All the way?)
Cover air box (optional?)
Hook machine up to any single vacuum hose (brake booster?)
Did I leave anything out? Anything I got wrong?
Many thanks!
Can I not use a vape and a hose to do the same progress
Is there any part of the soldering iron that is touching the rag? Or is it just to heat the air inside the jar?
damn i tried this and it did not quite work. Smoke was created indeed but it mostly came out of the soldering gun.
so that was actually 80 bucks stomach ache machine, because the Pcv valve is probably 70 bucks itself already and the smoke smells like cats anaI tubes
