I have yet to see one internal combustion engine not produce smoke when properly seafoaming.
You have to get the engine almost to the point of dying while introducing the seafoam to it then actually make the seafoam kill the engine at the end.
I promise you it will smoke when you crank it up and drive it after 20 minutes.
Yep, that's what I did. Poured a bit in the gas and then sucked up a cap full through the vacuum/brake booster hose that goes into the intake manifold...sucked it up until the truck ran rough and eventually died. Let it sit for 15-20 minutes then cranked it back up and drove the dog piss out of it on River Rd...then came back and did an oil change.
It may have smoked a little bit...but it certainly wasn't a huge cloud like I'd heard others have gotten.

TL;DR
nahh,you may have had a really effecient catalytic converter. The seafoam itself is what smokes when exiting the exhaust,not the carbon buildup it breaks down.

Well...that would be plausible if I had catalytic converters at the time
Pretty sure that was when I had LT's and cutouts on the truck with no cats...or just one small high flow cat after the Y (it was a weird LT and Y pipe set up).

I did it on my old trucks by sucking it into the brake booster vacuum line. I could kill it is a few seconds by pouring too much, but the objective was to suck more of it further into the intake, so you must not let the hose get completely covered by the Seafoam. Just do a little at a time out of a spraay paint can top. It smoked like hell when you let it sit for the recommended time.

i run seafoam in m truck and bass boat. never heard of running it through the pcv valve. is that like main lining or something??

basically cleans the intake by sucking it in through vacuum pressure
you can put seafoam in fuel(to clean fuel system), in your intake, and in your oil(I have never used it that way). It is a good way to clean carbon buildup out of your intake and parts of your fuel system
Just a word of caution for those putting it in your vehicle...It can sometimes mess up your O2 sensors or throw an O2 code

Carbon buildup in the intake and manifold can also be taken care of using this:

51 pages of SeaFoammmmmmmm!!!!!!!!!!!!!

All you need is on the first page. The best is the youtube vids of people smoking out their neighborhoods.

Could one of you explain this?

Man...I guess people are just gonna keep using SeaFoam to TRY to clean their top ends............
If you're gonna waste your time with a liquid like SeaFoam to do this.....for gods sake, at least use the PCV vacuum port to administer the SeaFoam into the intake....this way the liquid, once it gets sucked in, will at least travel the length of the intake and get picked up by all 8 runners. Most will get sucked up by the front 4 runners and the rear 4 runners will get MUCH less...but at least its not going into the rear of the intake (brake booster line) and fighting the incoming air from the throttle body like salmon swimming upstream..... lol

More from same poster:
quote:
Ok....as you pour SeaFoam into the brake booster line it immediately gets sucked up by the rear two runners....the front 6 cylinders get pretty much nothing. So you are cleaning the two rear cylinders. Also, fluid is heavy and gets sucked right through the engine and has no time to sit and soak inside the engine....it does nothing. Allot of that SeaFoam that gets poured into the brake booster line pools in the intake also and sits in the rear of the intake.
The smoke show is mainly that SeaFoam getting sucked up when the engine is started later on. I'd be willing to bet that if someone does a Brake Booster Line SeaFoam job, a whole can, then removes their intake BEFORE starting the engine, they will pour allot of SeaFoam onto the ground. Then reinstall it and start the engine......no smoke show. Fluids of any kind are not meant to go through an intake where AIR should be going through.
If you pour it too fast, the rear two cylinders almost stall the engine because they're getting drowned out by the liquid.
You also run the risk of getting too much SeaFoam into a cylinder and hydra-locking the engine...BYE-BYE engine.
They make products that do this job properly....Mopar Combustion Chamber Cleaner (MCCC) and GM has one also. They are FOAM.......so when you spray them into the FORWARD PCV vacuum port this foam travels with the incoming air from the TB and travels to ALL 8 cylinders, (((unlike using the brake booster line and the SeaFoam having to fight against that flow of incoming air))). Which is doesn't, it gets sucked up by the rear two cylinders only. This foam also expands as it sits, so it bloats itself throughout the intake, runners, heads and cylinders...touching all of the inside surfaces to eat away the build-up of crap inside. Fluids can't stick to walls and ceilings, they fall to the bottom from gravity. This foam sits and eats.
I did two full cans of SeaFoam in one week....until I popped my head up and said, "what the hell am I doing, this is a joke." The next week I did one can of MCCC, and it smoked more than both SeaFoam treatments combined.
SeaFoam is GREAT for the gas and to clean out the crankcase during an oil change.
I have been using SeaFoam for almost 14 years in my 1998 T/A. Every 3-4 months a put a full can into 1/8-1/4 of a tank of gas to clean my entire fuel system, from gas tank to filter to lines to injectors to valves. I personally don't use it for oil changes, I use GUNK engine flush at every oil change.
Thats it...........

I'll try my best...
He's basically saying that if you suck up the seafoam into the intake manifold with the brake booster line, then the liquid will be trying to go "upstream" against the air that is coming in from the throttle body (brake booster line is normally at the rear of the intake manifold). Therefore, the seafoam liquid will only make it into maybe 4 of your 8 cylinders (assuming a V8).
Whereas if you suck the seafoam up from the PCV, the seafoam will be coming from the front of the intake manifold, or "downstream", with the air coming in from the throttle body. The runners he is referencing are the intake runners which are the lower part of your intake manifold that are responsible for directing air to each of your 8 cylinders (once again, assuming a V8).
ETA: Reading over his longer post, looks like I found the reason why I didn't get a smoke show on my old truck...sucked up the seafoam via the brake booster vac hose.

I used the spray directly in the throttle body( I think) so maybe I'm not one of the dummies he keeps piling on.

Throttle body is just the butterfly valve normally in the front, or on top, of the intake manifold. I think you'll be fine if that's where you poured the seafoam. I guess the tell tale sign as to whether you did it right or not is if you get any smoke.
ETA: And boat motors will smoke most of the time because they normally consist of a V4 or V6 mounted straight up and down...so the seafoam is carried by gravity to all the cylinders. At least I think that's how it works, I'm no mechanic :meauxjeaux:

Well shite. That's convenient. When I did my old truck, I had to pour some in the cap and suck it up into the intake manifold. Spray seems a lot easier.
Posted on 5/3/12 at 8:26 pm to jordan21210
I may be done with SeaFoam. I have a feeling I'm going to move on to Mopar CCC 
Posted on 5/3/12 at 8:30 pm to dstone12
PCV stands for Positive crankcase ventilator. I think you contaminated your oil.

Seafoam is so damn awesome
