Model and Year? 99 4runner
PCV or Brake Booster Line for Intake? brake booster
Amount of Seafoam Used: about 1/2 can
Location(s)- Intake, Crankcase, or Gas tank: just intake
Amount of time it sat before restart: approx 1 hour
Duration and desciption of smoke: approx 10 seconds of intense, followed by about 30 seconds of light smoke, white/grey
Following Gas mileage experience: a little increase, not much
Other relevant notes: followed up with oil change the next day...gas mileage didnt increase as much as i would have liked; decided that putting in gas tank will probably yield best results, but would get tedious doing it every time i fill up

Model and Year?: Lexus ES 300 (camry) 1993 (3vz-fe)
PCV or Brake Booster Line for Intake? Vacuum testing port on the side of the Intake Air Chamber
Amount of Seafoam Used: 2 cans of seafoam (1 in march, 1 in april '05), applied three times in 2/3 cup incriments. (Measure out into a seperate cup, put your finger on the end of the line to stop a vacuum leak, dip line in the measured amount, release finger - engine stalls. If not Immediately shut it down). The engine should be warmed up to temperature before you treat it.
Location(s)- Intake, Crankcase, or Gas tank: Intake, Crankcase, Gas tank (And transmission)
Amount of time it sat before restart: exactly 5 min... Like the OLD can's of seafoam suggested
Duration and desciption of smoke: 5-10 min, heavy on all applications
Following old directions, the engine idled until smoking started dieing down. Then the car was driven until the smoking stopped. Making liberal use of the top RPM range a few times before it all burns out
Following Gas mileage experience: Unknown. Too many mods at one time to form an opinion, but record 28mpg over 400highway only miles was achived while clean.
Other relevant notes:
Before Seafoam:

8/9 months after following my directions for a seafoam treatment. (So there's more coloration than if I tore it apart a few days after finishing)

Seafoam does not clean the intake. Neither will a carb cleaner, or any other such thing. To clean the intake track you have to take it off & clean it by hand, be that with a brush, or a rotary cleaning tool.

Sorry to break the format, but yall haven't seen compairison pictures before

*Edit#2* (#1 was a bad pic) A little fakey. The middle cylinder had a blown headgasket, which is why that piston is so much cleaner than others.
Here is a better pick of the #6 piston (right most in the top pic).

Notice all black carbon is gone & it's golden/brown.

PCV or Brake Booster Line for Intake? PCV

Amount of Seafoam Used: 1.5 cans in the intake, 1.5 in the gas tank

Location(s)- Intake, Crankcase, or Gas tank Intake, Tank

Amount of time it sat before restart:
1/4 can in the intake, sat 30 mintues, started.
an hour or so later, 1/2 can in the intake, sat 2 hrs, started.
a week or so later, 3/4 can in the intake, sat several hours, started.

Duration and desciption of smoke:
So smoky I was worried my apartment neighbors would complain as it wafted up to their balconys. The last time, I smoked it out while driving down the road and got a lot of looks. And my wife hated me for the smell.

Following Gas mileage experience:
Gas milage didn't change

Other relevant notes:
Throttle response was better.
I didn't think there would be much change because I had my head gasket done and the valves reground about a year before I did the treatment.

I'll probably do it yearly just for maintinance.

PVC line used and gas tank
I used about 1/2 can in the PVC and half in the gas tank.
Ive done it a few times and let the truck sit with it from an hour to overnight.

i used it after i rolled my truck to help clean out the engine. the smoke lasted at least two hours but that is because the oil from the roll was burning off. gas milage probably stayed the same but the engine seemed to run better. less noise, just felt cleaner. ill do it about once a year now.

Joyota · 10-16-2005, 06:56 PM

Model and Year? Pickup (22re), 1989

PCV or Brake Booster Line for Intake? PCV

Amount of Seafoam Used: 2 cans (2/3 can in intake, 2/3 can in crankcase, 2/3 can in gas tank, with 1/4 tank of gas)

Location(s)- Intake, Crankcase, or Gas tank: Intake, Crankcase and Gas tank

Amount of time it sat before restart: 20 minutes

Duration and desciption of smoke: About 3-4 minutes. It started getting thinner after about 2 minutes.

Following Gas mileage experience: No noticeable difference

Other relevant notes: After finishing up with the 2/3 can in the tank, I drove it like a hot-rod for about 10 minutes to the nearest gas station, filled the tank, then drove normal back home. I too noticed a little better throttle response as well as a smoother idle. This was done last November, about a month after changing the head gasket. I plan on doing another treatment again this November, before the snow settles.

X-AWDriver · 10-19-2005, 09:51 AM

Never used it but I do run a can of BG's 44K through the fuel system once a year of all my vehicles and that has done the job for me. My '99 with 109k idles perfect and don't see a need to seafoam it but maybe before 150k.

PCV or Brake Booster Line for Intake? PCV

Amount of Seafoam Used: 2 cans down PCV-3 down fuel tank

Location(s)- Intake, Crankcase, or Gas tank: Intake and Fuel tank

Amount of time it sat before restart:15 and 30 minutes. I'd like to do a 3-4 hour job though.

Duration and desciption of smoke: Small wispy amounts of white/gray smoke then great plumes of malovent fog!!

Following Gas mileage experience:18-20 with 4.10's 16-17 with 4.56's

Other relevant notes:I now only use the SeaFoam in the PCV as COSTCO has the Chevron with Techron injector treatment for $10.00(4 bottles). I also use Marvel Mystery Oil in the Crank about 1,000 to 500 miles before an oil change. I changed my plugs following the last treatment...didn't need to though. I've wondered about a little Marvel Mystery Oil (MMO) down the PCV as it is a thicker like ATF and would sit on the pistons and not atomize quite so quick. I've never used SeaFoam in the tranny.

youngbuck · 11-20-2005, 02:45 PM

2001 Tacoma 3.4L

PCV Line

2 treatments of 1/3 can in PCV Line

1 Full can in gas tank

Each time I let it sit for about 15-25 minutes. The smoke started out fairly light and white, and then after about 20-30 seconds it got much thicker and billowed out. First time I think the smoke lasted about 5 minutes, and then the second time it lasted 3.5-4.5 minutes.

Didn't really notice any gas mileage improvements, mainly because I was in 4wd a lot the next few tanks.

I did notice that things ran a little smoother though, smoother throttle response and idle. I changed my spark plugs several weeks later and they looked BAD. They were definately due for a change before the treatment, but I suspect the seafoam treatment made them even worse. Something to keep in mind if you put the stuff in your throttle body via PCV or brake booster line.

You guys should really try letting it sit overnight... it does even more good. Just forewarn your neighbors on the restart.

Yeup... All the crud that comes off has to go somewhere, and the plugs seem to be a heck of a collection point for it.

bob200587 · 01-03-2006, 03:41 AM

Model and Year? 1987 4runner 22RE

PCV or Brake Booster Line for Intake? PCV

Amount of Seafoam Used: 2 Cans: 1/3 in the intake 2/3 crankcase 1 can gas tank. (I would proabably use more in the crank next time)

Location(s)- Intake, Crankcase, or Gas tank? All 3

Amount of time it sat before restart: around 45 mins

Duration and desciption of smoke: Heavy white smoke for 5 mins or so, followed by light smoke for a short time after

Following Gas mileage experience: I did the treatment on Dec 17, it is now the 3rd of Jan. and I have yet to have to fill my tank.

Other relevant notes: I found that the intake benifited from having the aresol spray intake cleaner I had after running the seafoam, and also Cleaning the inside of the plenum with a rag. A rotary rag type brush that could be used with a electric drill would do the best. I recommend a manual cleaning in addition to the seafoam.

I also cleaned my plugs with a wire brush and a clean cloth after running the engine for several miles. I'm sure using seafoam or starting fluid would have helped clean them off too. I suggest checking the gap before reinstalling.

I noticed a ton of crud cleaned out of my motor, and it made it run smoother and I can feel a difference in power, I'm sure the next time I do the treatment It won't be as substantial, but my engine was pretty dirty in there so it seems.

I would recommend seafoam to anyone who even thinks they might need it.

spindleshanks · 01-06-2006, 06:05 AM

Sorry to hijack this thread, but this is ridiculous.
Seafoam is just like any other oil supplement/treatment/fuel treatment/engine flush. It's made of petroleum distillates, just like Marvel's Mystery Oil, B&G, Lucas Oil, and the like. You can make your vehicle run better putting anything through the fuel and crankcase...I once used a bottle of ATF in the fuel tank of my Mustang, and the guy was right..it was the best stuff to clean off valve deposits. It smoothed my idle and improved my gas mileage. I think if you put a bottle of Aunt Jemima through your system it would probably do the same.
If you're gonna do it, do it right and get hold of a pressurized "weed sprayer", use a can of aggressive fuel system treatment, mix it with fuel according to the directions, disable the fuel pump, and run the engine off of the mixture. Nothing...I mean NOTHING cleans fuel injectors better! The difference on a 100k mile engine will startle you.
As for the crankcase, just use the engine flush (really just a can of diesel for $2.99) at your parts store and follow the directions. Your engine won't smoke, although it will not be happy while you run it with the flush in there. It's all voodoo guys.

How is it "ridiculous" and "all voodoo" if it's cleaning off deposits?

I don't think that any of us are claiming that it's anything more than something to get the grime off of the valves and pistons, and blow out injectors. I'm not.

We're all saying what you said... run a can through the intake and dump another into the crankcase to get the engine to run smoother/better.

Doubtful. given that pancake syrup doesn't have the petrolium distillates in it, I doubt it woudl have the same effect. In fact, the sugar would actually gum things up.

X-AWDriver · 01-06-2006, 09:21 AM

The same thing was a popular cleaning method using ATF fluid on DSMs (Eclipses,Talons,Lasers) and it all works.

I just used Seafoam with the urging of a friend who helped me and I'm sure I got some cleaning in the engine done but no noticeable effects on gas mileage or idle.

I don't think I'd go through the hassle of doing it again since my yearly regimen of using BG's 44K once a year is probably taking care of things just fine.

spindleshanks · 01-06-2006, 11:38 AM

Yeah, sorry guys, I got a little rude there. That pancake syrup comment was uncalled for and highly illegitimate. And completely, absurdly hilarious. If I'd have commented about Log Cabin maple syrup, you know, it wouldn't have been as comical, because the bottle isn't shaped like a chick.
I was amazed at how specific the procedure was. It just sounds like shadetree mechanics to me; buy a bunch of 'wonder oil' and pour it into every hole the vehicle has, ignore the smoke, then drive like a demon all over town before changing your oil. It sounds like a decathlon of ridiculousness. But hey, you can't argue with results!

PCV Amount of Seafoam Used: 2 cans (2/3 can in intake, 2/3 can in crankcase, 2/3 can in gas tank, with 1/4 tank of gas) Location(s)- Intake, Crankcase, or Gas tank: Intake, Crankcase and Gas tank Amount of time it sat before restart: 20 minutes Duration and desciption of smoke: About 3-4 minutes. It started getting thinner after about 2 minutes. Following Gas mileage experience: No noticeable difference Other relevant notes: After finishing up with the 2/3 can in the tank, I drove it like a hot-rod for about 10 minutes to the nearest gas station, filled the tank, then drove normal back home. I too noticed a little better throttle response as well as a smoother idle. This was done last November, about a month after changing the head gasket. I plan on doing another treatment again this November, before the snow settles. __________________ ~ Joe ~ '89 4WD Pickup, Std Cab, 22RE, W56, 4.10's {REPAIRS} Head Gasket, Timing Chain Guides, Water Pump, Alternator {MODS} Flatbed, Turn/Parking Light, SR5 Cluster, SR5 Lighter, SR5 Clock, 750W Inverter {ACCESSORIES} 33x12.5 on 15x8's (no lift), Radar Detector, CB, Contico Tool Box, Pilot Driving Lights, Fiamm Freeway Blaster {WAITING} Portable Air Tank, Big 3, Hood Scoop Last edited by Joyota; 10-16-2005 at 07:01 PM.

My '99 with 109k idles perfect and don't see a need to seafoam it but maybe before 150k. __________________ '99 4Runner Highlander 4wd E-locker,rear diff and deckplate mod * 265/75/16 Nitto TerraGrapplers * Yakima Load Warrior rack * clear corners/signals * Tacoma skidplate * Silverstar lamps/fogs Alpine CDA-9831,Bazooka EL Series 250w amp,MTX 10" sub

PCV Amount of Seafoam Used: 2 cans down PCV-3 down fuel tank Location(s)- Intake, Crankcase, or Gas tank: Intake and Fuel tank Amount of time it sat before restart:15 and 30 minutes. I'd like to do a 3-4 hour job though. Duration and desciption of smoke: Small wispy amounts of white/gray smoke then great plumes of malovent fog!! Following Gas mileage experience:18-20 with 4.10's 16-17 with 4.56's Other relevant notes:I now only use the SeaFoam in the PCV as COSTCO has the Chevron with Techron injector treatment for $10.00(4 bottles). I also use Marvel Mystery Oil in the Crank about 1,000 to 500 miles before an oil change. I changed my plugs following the last treatment...didn't need to though. I've wondered about a little Marvel Mystery Oil (MMO) down the PCV as it is a thicker like ATF and would sit on the pistons and not atomize quite so quick. I've never used SeaFoam in the tranny.

youngbuck Contributing Member Join Date: Sep 2005 Location: Colorado Posts: 196	2001 Tacoma 3.4L PCV Line 2 treatments of 1/3 can in PCV Line 1 Full can in gas tank Each time I let it sit for about 15-25 minutes. The smoke started out fairly light and white, and then after about 20-30 seconds it got much thicker and billowed out. First time I think the smoke lasted about 5 minutes, and then the second time it lasted 3.5-4.5 minutes. Didn't really notice any gas mileage improvements, mainly because I was in 4wd a lot the next few tanks. I did notice that things ran a little smoother though, smoother throttle response and idle. I changed my spark plugs several weeks later and they looked BAD. They were definately due for a change before the treatment, but I suspect the seafoam treatment made them even worse. Something to keep in mind if you put the stuff in your throttle body via PCV or brake booster line. Last edited by youngbuck; 11-20-2005 at 02:46 PM.

PCV Amount of Seafoam Used: 2 Cans: 1/3 in the intake 2/3 crankcase 1 can gas tank. (I would proabably use more in the crank next time) Location(s)- Intake, Crankcase, or Gas tank? All 3 Amount of time it sat before restart: around 45 mins Duration and desciption of smoke: Heavy white smoke for 5 mins or so, followed by light smoke for a short time after Following Gas mileage experience: I did the treatment on Dec 17, it is now the 3rd of Jan. and I have yet to have to fill my tank. Other relevant notes: I found that the intake benifited from having the aresol spray intake cleaner I had after running the seafoam, and also Cleaning the inside of the plenum with a rag. A rotary rag type brush that could be used with a electric drill would do the best. I recommend a manual cleaning in addition to the seafoam. I also cleaned my plugs with a wire brush and a clean cloth after running the engine for several miles. I'm sure using seafoam or starting fluid would have helped clean them off too. I suggest checking the gap before reinstalling. I noticed a ton of crud cleaned out of my motor, and it made it run smoother and I can feel a difference in power, I'm sure the next time I do the treatment It won't be as substantial, but my engine was pretty dirty in there so it seems. I would recommend seafoam to anyone who even thinks they might need it. __________________ 87 4runner 4x4 SR5 22RE ARB Bull Bar, 31X10.50 Mastercraft M/T's, Stock 4.10 Gears, Flowmaster Muffler, LCE Header AISIN Manual Hubs, Marlin Crawler Sliders 190XXX miles Last edited by bob200587; 01-03-2006 at 03:44 AM.

Seafoam is just like any other oil supplement/treatment/fuel treatment/engine flush. It's made of petroleum distillates, just like Marvel's Mystery Oil, B&G, Lucas Oil, and the like. You can make your vehicle run better putting anything through the fuel and crankcase...I once used a bottle of ATF in the fuel tank of my Mustang, and the guy was right..it was the best stuff to clean off valve deposits. It smoothed my idle and improved my gas mileage. I think if you put a bottle of Aunt Jemima through your system it would probably do the same. If you're gonna do it, do it right and get hold of a pressurized "weed sprayer", use a can of aggressive fuel system treatment, mix it with fuel according to the directions, disable the fuel pump, and run the engine off of the mixture. Nothing...I mean NOTHING cleans fuel injectors better! The difference on a 100k mile engine will startle you. As for the crankcase, just use the engine flush (really just a can of diesel for $2.99) at your parts store and follow the directions. Your engine won't smoke, although it will not be happy while you run it with the flush in there. It's all voodoo guys. __________________ '03 beauty of a white Tacoma, check it out: http://www.yotatech.com/f83/spindles.../#post50606613 "The fingers you have used to dial this number are too fat.

X-AWDriver Contributing Member Join Date: Sep 2003 Location: Littleton,CO Posts: 10,174	The same thing was a popular cleaning method using ATF fluid on DSMs (Eclipses,Talons,Lasers) and it all works. I just used Seafoam with the urging of a friend who helped me and I'm sure I got some cleaning in the engine done but no noticeable effects on gas mileage or idle. I don't think I'd go through the hassle of doing it again since my yearly regimen of using BG's 44K once a year is probably taking care of things just fine. __________________ '99 4Runner Highlander 4wd E-locker,rear diff and deckplate mod * 265/75/16 Nitto TerraGrapplers * Yakima Load Warrior rack * clear corners/signals * Tacoma skidplate * Silverstar lamps/fogs Alpine CDA-9831,Bazooka EL Series 250w amp,MTX 10" sub

spindleshanks Registered User Join Date: Nov 2005 Location: Loveland, CO Posts: 620	Yeah, sorry guys, I got a little rude there. That pancake syrup comment was uncalled for and highly illegitimate. And completely, absurdly hilarious. If I'd have commented about Log Cabin maple syrup, you know, it wouldn't have been as comical, because the bottle isn't shaped like a chick. I was amazed at how specific the procedure was. It just sounds like shadetree mechanics to me; buy a bunch of 'wonder oil' and pour it into every hole the vehicle has, ignore the smoke, then drive like a demon all over town before changing your oil. It sounds like a decathlon of ridiculousness. But hey, you can't argue with results! __________________ '03 beauty of a white Tacoma, check it out: http://www.yotatech.com/f83/spindles.../#post50606613 "The fingers you have used to dial this number are too fat.
