Can I be sure water vapor isn't being sucked into a cold engine? Sure, I could put the whole system on a switch, solenoid, tee fitting but why do that? It isn't like it is 30 degrees outside, ever, or hardly ever here. If I still lived in the Upper Michigan area I might think about that. But really, Roids, you know what it is like on the coast. 40 to 60 all year round. How boring right?
In all honesty it takes a while to get vapor to show up in the hose. Like 3 to 4 minutes so it isn't like a fog is rolling around in the intake right after it fires off.
I thought about the end of the cycle though. After a long run, like mine to Portland. To be able to shut it off and let it vent to the outside instead of putting it to bed wet. Not good for horses, probably not good for rabbits either. I am scheming a system that would allow me to do that. My idea is use a lawn sprinkler system solenoid that dumps the blow by to the outside. I could then just engage the switch and let it go. I could use it when cold in reverse. Wait about 5 minutes and let it vent, then dump it into the intake.
