Seafoam'd the 4Runner

Seafoamed my new (to me) 2003 T4R tonight. Easily the most amount of smoke i have ever had seafoaming. I am at about 103k right now, and although the service records are complete and regular, i figured it wouldnt hurt. Idle dropped slightly, and seems to run a bit smoother, although that V8 is already pretty darn smooth.

I think that is it...my wife used to drive this car and she insisted on using the ****ty gas. I have never seen so much smoke before, and it last a while

What kinds of gains if any are you guys seeing. Honestly I feel like if it was really burning any crud out of the engine it would burn off black. Though I can't deny that the engine does SEEM smoother. Like, no joke. However I was disappointed that I saw no gains in mpg's. I used to get like 20-21 a few years ago when gas was really high and I paid attention. Well I'm paying attention again and I'm getting 17.5 avg now. Well I dumped 20oz of this stuff in my tank on my last fill up and and I hit 130mi on the first hash mark of the fuel gauge. I also took a fairly long freeway drive like 60-70mi but I was cruising at like 70-75. However I still want to say it's been a huge improvement. I tried that Lucas oil garbage and it made my mpg's worse. Well see how sea foam works. Right now, I'm impressed, but it's still early. I'm definitely going to put some in the oil before my next change in a week or so.
99,600 miles on my 04 V6
Never even heard of seafoam until a few weeks back and wanted to wait until I had to change my oil to put into all three (3) areas (gas, oil & vacuum line).
Cleaned the MAF (aftermarket K&N) and throttle body while I was at it (used CRC).
1st warmed the engine up for 10 minutes. Then allowed vacuum line to suck in 8 oz while engine was on. Turn off motor and stuck the other 8 oz in the oil and a full bottle in the gas tank with about 3/4 of the tank full.
Turned the motor back on and didn't get as much smoke as I thought I would. Def. not as much as the original poster in this thread that posted the Youtube video. My VSC and check engine lights did come on so I reset them. I was getting about 15 mpg but my wife mostly drives city rather than highway so we will see if their is any improvement. I imagine she should eb getting at least 18mpg. We used to get about 400 miles out of a tank according to to the display but only get about 300 now.
Only issue I think the engine seems to be idling a bit high right now. About 1,500 rpm. Is that normal?

I have 190K on my T4R- and am going to Seafoam the motor today or tomorrow. I at this time am noticing a rough idle- I JUST changed the plugs and air filter. I am imagining the cloud of smoke should be pretty intense.
I'm going to try to remember to record it.

I just did it. Lots of smoke. When I drove it I put it in L gear and kept it at about 4K RPM for about 500 ft.

just throwing this out there to play devils advocate...
seafoam CAN go wrong. if your engine has never had the seafoam treatment before and you are at a higher mileage, there are risks involved. this mostly applies to engine's that have been neglected in terms of oil changes, among other things.
sometimes, the gunk and that builds up in your engine "assists" in keeping worn, sloppy parts within tolerance as they wear down. additionally if you have ALOT of build-up, its going to knock those loose and send them through the rest of the engine. the last thing you want is a chunk getting sent through your valves or put you on the way to a spun bearing.
seafoam is a great product. i am as american as it gets, but the japanese do 4 wheels and a motor the right way (and 2 wheels and a motor), point being that the majority of horror stories are from american vehicles where gm, ford etc. are WORKING to get 200 hp out of say a V6 and thus the engine is quite a bit more stressed, whereas toyota easily got 250 hp and tuned it down to 200 hp for the longevity of the engine (just an example).
(this also applies to things like transmissions where the crud build up after x amount of miles is actually "helping" the transmission (really just masking the problem) and thus a full flush isn't good.)
basically, its a yota and it'll love seafoam 97% of the time. i just want everyone to be aware there is a possibility for a negative outcome.

Did you really clean the MAF sensor? If you look inside the tube, there are two elements inside. Mine looked clean, so I did not bother spraying.

SeaFoam'd my 4Runner today. 91K on the Odo. Very interesting.
Please forgive the unsightly appearance of the T4R. We have had too many days of rain to have a chance to give her a bath.
Has any body repeated the process after about 1,000 miles or so?

Good results! What tube did you pour the can down?

I used the vacuum tube identified on page 6 of this thread. Driver's side valve cover line. I would assume that is the PCV vacuum line. I could be wrong.
I recently got a 06 4runner from a friend with 225,000 on it. Its been well taken care of for the most part and most of the miles are highway. Oil changes regularly and that was about it I think. Ive serviced other things like spark plugs and the differential and would like to seafoam it as well. After reading that post, I'm skeptical... would people advise against it? Car runs great with no problems in the last 3 months Ive had it.

Miracle drug
I have been using this stuff for years. Some results I have seen (old Ford Aerofart van) were so astonishing it was hard to quantify, sort of a mechanical resurection. I rebuilt a 22R just days after running Seafoam through the oil and gas. It had zero carbon deposits. Too bad it didn't fix the broken timing chain guide and head gasket leak....

Ran 8oz. through my vacuum lines this weekend. Super easy, and this stuff is amazing!!! I got my 05sport with 48,000 miles and it never ran that great. I never realized how much loss in pick-up I was dealing with.
Also did my buddies 09 Tacoma with 28,000 miles... He had more white smoke than I did at 101,000. He could tell a noticeable difference also.
Just dumped a can in my gas tank, cant wait for my next oil change to dump in crank case.
This stuff works!

Just did my 2nd annual seafoam job and not as good a result as the first go round. Put 8 oz in each the vacuum line and oil crank case (in that order), then a full 16 ounces in a full tank of gas. Last time I did it my mileage estimator was at 411 range, this time 311. Changed the oil about 50 miles later as recommended. Did get more smoke this go round though.
