Hey guys, i wanted to know if anybody could help me. Is there anybody that has an airflow chart, air going through the air intake and etc. There is a rubber hose that is right before the throttle that goes to the rocker arm housing. Is air going into the hose into the rocking arms housing, or is the throttle sucking the air out of the rocker arm housing to create a vaccuum in there?

The reason why Im asking is because I want to experiment on a HHO System. As i was looking at the installation instructions, I'm suppose to put a valve before the throttle body near the end of the intake tube, after the air sensor, so that the HHO can be sucked into the intake manifold by the throttle, thus mix with the fuel. However there is another valve there that connects to a rubber hose and attached to the rocker arm housing. If that rubber hose is sucking air into the rocker arm housing, i assume it will suck in the hho as well which totally contradict the purpose, which is making the throttle suck in the hho to the intake manifold. You guys see what I'm saying?

So to put it in a simple way, does that rubber hose sucks air from the air intake into the rocker arm housing, or does the air intake/throttle body suck out air from the rocker arm housing causing a vaccuum in there?

I would appreciate it if anybody could enlighten me.

 

It's all under vacuum up until the throttle body. So the hose that is going into the valve cover is sucking from the cover into the throttle body.

I'd really advise you to reconsider adding this system. There are some potential serious consequences and risk to your engine by using such a system. In general, these systems are thought up as merely snake oil marketing and just don't work.

 

Thanks, i figured that, I disconnected the hose and plugged it with my finger, i felt a slight suction, this is good news for me. i know theyre are cons with the hho system but i have read many pros and success stories. I read all the precautions and as long as follow the guidelines no damages will be made on my engine. I'll keep you posted on results!!
