I seafoamed my 3vze
I have been hearing and reading all sorts of good stuff about seafoam and figured I would give it a shot. I used the brake booster vacuum line. Poured it in and the engine instantly started gurgling and sputtering and the smoke started right away. I shut off the engine and waited the 5-10 minutes. Fired it up again and sure enough it insanely smoked. Results? Eh....idles really smooth. Haven't noticed too much of an increase in power or throttle response yet. I am waiting to see if the fuel mileage improves. I have heard it may take 2-3 cans to make a difference. Here are some pictures cause everyone likes pictures
This is the line I used to pour the seafoam in.
This is where that line feeds into.
As you can see, this line feeds everything. (if not, i admit, im not the most knowledgeable guy on mechanics lol)
What are your seafoam experiences? Are there any better products?

Brake booster line won't feed all cylinders. I've read lots of good stuff about Mopar Combustion Chamber Cleaner and I'm gonna play around with it. It's a spray foam instead of just a liquid

I did the trifecta style SeaFoam treatment on both my Pathfinder and 4runner, all it did to either of them was make em smoke for a little bit. Coulda probably had the same effect spraying water into a vacuum line. Waste of 10 bucks to me

after seeing this, it reminded me to do mine as i already had a can. i did mine thru the port just before the throttle body because i wanted to clean the throttle body as well. i just turned up the idle so it would have enough vacuum. i think i need to do it a few more times as it didnt smoke nearly as much as my accord i did a few years back or maybe the runner is just that clean lol

Sea Foam also comes in a spray, it's called Deep Creep. I've tried that through the brake booster line and it didn't work as well as dumping the Sea Foam in it. With the spray it barely affected the idle and barely smoked...nothing like the Sea Foam does. I don't think enough product comes out in the aerosol form, and what little does, gets atomized even more as it gets pulled through and isn't concentrated enough to do much. It's mostly made for de-carbing outboard straight through the carbs.
I also never saw much difference after Sea Foaming though, a lot of smoke and pretty much no difference in running afterwards.

i think you guys are doing it all wrong forget the lil bottle. get the gallon and do it that way i parked over near all the car parts stores in a big huge unused parking lot, let it suck till it died waited 30 mins. started back up i thought i was gonna have the epa out there then did it again i think before my rod went out the side of the block my truck needed seafoam (musta been like a drug)

I believe it says on the bottle not to drive with Seafoam in your crank case. Just pour it in and let it idle, then change your oil

you dont need to change the plugs after running sea foam (if it cleans the pistons and head then its cleaning the spark plugs as well. i dont have a can handy but i belive the only thing they recommend changing to oil after a short interval of running it in the crank case is on diesel engines. personally iv never added it in the crank case because its so thin, i prefer to add some atf in the crank case when i want to clean the crank case. or just run synthetic oil.

i have never changed plugs after doing seafoam. i dont use what they recommend anyways. i just added just a little less than 1/3 of the bottle to the oil. a little less than half into the gas tank and the rest into the intake. gonna a 3rd again into the intake after the oil change.

I've got a 89 3vze that had been parked since 2002. It's my first Toy. Gas tank was full of gunk, fuel pump was seized. I cleaned out the tank, put in a new pump, and got it fired up. It was missing pretty bad so I did a leakdown test and 3 of the cylinders were low, 50-60%. I could hear the air coming out the throttle-body which means stuck or leaking intake valves. As a long-shot I tried a $10 bottle of seafoam before diving into a valve job. There was only about a gallon of gas in the tank so I put about 1/3 can in the tank. The significance of that is that it was fairly concentrated. The other 2/3 I sucked in using a vacuum port. I did not use the brake-booster line as that looks like it would hit the back 3 cyl's harder than the front, although it would have been easier.
After the treatment it was still missing but another leakdown test showed that it freed up the stuck intake valves!
I ran another can through for the heck of it, still missing. Two cylinders are now at 91% and 86% leakdown, both by the rings. If I squirt some carb cleaner in the vacuum fitting the motor revs up so it's starving for fuel. Also it doesn't miss when it's cold. My theory is the injectors or the screens on the injectors are clogged with rust scale from the tank, which seafoam won't help with. And the reason it runs well when cold is the cold start injector is giving the missing cyls enough fuel to fire, until it warm up.
Your mileage may vary...
