Fogging question

[Geiger41]

When fogging, do I need to take this air box off completely or can I just undo the small hose shown in the middle of the picture that connects to the very large hose and spray it into the large hose from that opening ? Trying to bypass having to take this airbox off ...

I fog directly in cylinders by pulling the plugs.

Yeah I've seen that also, I'm not really trying to do that... I appreciate your response though !!

My motors are naturally aspirated, so I’m not sure how much the supercharger restricts fluid flow. The key step is to remove the spark plugs at the end and spray directly into the cylinders. The idea is to coat the cylinder walls, since that’s the area most prone to corrosion, and protect them from rust caused by moisture. I do wish the water box/muffler had a drain—when the leftover water evaporates, some of that moisture could easily work its way back into the cylinders.


a few weeks exposed to open atmosphere / rian the oxidation build up is amazing

So if your car or truck is going to sit for 6 months would you fog it down? Completely unnecessary unless it was going to sit idle for years.
Your cylinders are not exposed to the atmosphere. What happened to that block is not going to happen to an engine in your boat or car.
I have disassembled engines in my loft that have been open for years with no rust on the cylinders

If you take your old rotors off your automobile and put them outside they will look just like that so to show that as reference to what happens to your engine if you dont fog is not accurate

This doesn’t answer your question, but I disconnect the large hose at the engine and spray directly in there. (Careful not to suck in the straw). On the other engine, the space is so tight that I end up removing the tube from both the engine and the air filter box. Removing the cap for that does help but it can be done without removing it.

I’m interested in learning from someone about your question though. Maybe I’ll try the small hose idea if it works.

Yeah I still don't think I've gotten that exact answer for my question

You should never fog a supercharged engine before the intercooler. It will put unwanted oil film on the inside of your intercooler. This is why a lot of people and especially the performance guys put a catch can or breather to eliminate that hose.
Does that make it clearer. But if you are dead set of doing something totally unnecessary then just go through that small hose.

Your expertise doesn’t go unnoticed. I think answering his question would be helpful though, in addition to the advice. I may be wrong, but I think in your latest post, you are saying it’s okay to spray in the smaller hose. That’s helpful too. Thanks!
