ENG: Seafoaming an engine through the intake

Enjoy

interesting. I thought the motor was gonna go boom!

Thanks for the video, something to try in the near future

Never seafoamed a car before...

That's a good way to hydrolock your engine!
I believe it even says on the bottle to pour it through a vacuum hose.

[Junior Smurff]

Is their any advantage to seafoaming through there vs Brake booster Vacuum line??

Nope. I've done this one before and had no issues.

Always happy to help

Not at all. I did it exactly how I was supposed to. And that was a vacuum line.

Not that I know of. It was just easier to reach.

For those in doubt, seafoam does actually help.
The more smoke you have, the more carbon you're burning off.
The first time I did this a year ago, I had obscene amounts of smoke.
This time, I had much less smoke. I've also been using fuel injector cleaner fairly regularly.

vacuum hose = vacuum line, semantics..

I would go through the brake boost vacuum myself to avoid hydrolock. Not just dump it into the intake.

The EGR line he used in the video should be fine too though.

Whats the difference? They both lead right into the intake manifold

If you seafoam the brake booster your EGR will possibly get a clean as the gas recirculates.

No because the seafoam has been combusted by the time it reaches the EGR.

[wildBill83]

No because the seafoam has been combusted by the time it reaches the EGR.

If everything is combusted in the chamber then why do our engines need an EGR? In a perfect world, everything going in would combust.

Tippey, I know you know that EGR stands for Exhaust Gas Recirculation and is meant to recirulate unburnt fuel from incomplete combustion or rich situations. Seafoam will cause a rich combustion so some of it will go through the EGR.

Also if your motor is at idle and parked the brake booster is doing nothing, the EGR is still working, might as well let it do it's thing.

I was mainly talking about NOT dumping seafoam into the intake manifold without using the vacuum line method. This can cause hydrolock.

I really dont see how its any different. Its literally going to the EXACT same place.

Plus it looked like he dumped it into the PCV valve hose. Once again, same ending location as the brake booster hose

[wildBill83]

I really dont see how its any different. Besides the sea foam passing through the throttle body, its literally going to the EXACT same place.

How much Seafoam can pass through a 60mm opening vs a 5mm opening?

The difference is the amount of liquid that makes it to the combustion chamber. Liquids don't combust, gasses do.

honestly i just watched the video. I thought u guys were talking about dumping it in the intake, not the intake manifold. 2 different things
