Yep, my assumptions were correct. The longer you let it sit with the engine off, the longer the white smoke lasts. Also, I'd recommend revving up the motor between 1500-2000 rpms until the smoke clears.

Hey Andrey.. here in Tucson, I got 2 cans at Napa.. On Craycroft about 2 blocks south of 22nd St. its on the West side of the Street. It was somethig like 6.75 a bottle. They're open from 7am - 6pm Mon-Fri and also saturdays.

 

yo, where do i put seafoam in on my 22r?

 

Well, so far the engine is running much smoother, and this week, I'm planning to run it through my wife's Lexus and see what it does for it. I ran it through my tank with 2 cans, a can in my oil, and a can through my intake. It's got smoother idle, that's for sure!

I hope you changed the oil after a few hundred miles...

 

Vacuum line for the carb? Or down the throat if it is a top draft carb?

 

Thanks, I'll head to NAPA tomorrow to see if they have some. I leave Wednesday and get to Greenville thursday afternoon. once I get my high speed internet worked out up there I'll give you guys an update on the mileage I got from the whole 1000+ trip, 4 fillups or so, so I should get a good accurate mpg figure from the average.

 

Well, The sea Foam I reported working earlyer is no longer working. It lasted only three weeks and both my 3.0 and my father-in-laws ford 302 are both back to running rough. I guess I'll try running sea form thru again. I even used three cans on each vehicle. One in the PCV 1/2 in the oil and the rest in the gass. What's next. This has proven the plenium is gunked up.

 

I seafoamed my 4runner last night, figured enough people here were saying it worked that I should give it a shot.

Well, it definitely smoked like a chimney! My race teammate was over working on his bike, and was laughing his ass off at the smoke coming out. However it runs smoother and quieter now, definitely idles quiet. Perhaps a little power increase but not much (I also cleaned my K&N last night but am switching to AMSOIL at my next opportunity) - all in all I'd say it's worth the $4.75 I paid for the product, it really seemed to burn up a lot of stuff in there and clean it out. I used a 5oz treatment initially, let it sit for nearly 2 hours, then ran it out. Then did another 3oz treatment (pouring it a little faster this time), let it sit for about 15, then ran that out. A little more smoke the second time actually. I think I could have poured quicker the first go around. I used a measurement bottle from the BG44k kit I bought to get exactly 1/3 of the Seafoam can in there (plus it pours perfectly into the PCV hose and atomizes nicely as it goes). I may try more in a few thousand miles.

Waiting on my AMSOIL engine flush to get here along with the oil for my next change (which better get here quick, I'm definitely past due for this), hopefully that improves it even more.

I poured the rest of the seafoam into the gas tank (about 1/4 full in the tank, I think that's like 8oz of the cleaner in the tank - a little high on the concentration but ok) and will run that through to see what happens.

Should wind up with a happy motor by the time I get done with all of this! My next project will be to replace all of the vacuum lines and other hoses, after 101k miles they're showing the age. End of the PCV hose was cracked all over, though it still seems to seal more or less ok for the time being. Also going to either fabricate or find a fiberglass/something replacement for my intake tube - I like the ISR, but want a cleaner setup. I noticed that the Seafom that blew back down the intake tube (a little, but still there) leaked out of the bottom side of the tube where I stuck the PVC cap in there. It's *tight* around the cap but still leaked fluid, so now I have to question how airtight that really is. A solid tube would eliminate the potential for anything but filtered air getting in.

Also on the topic of mileage, I get about 18-19mpg with mixed driving at Colorado elevation (you WILL see less mileage at sea level, more power = more fuel, think about it). I've had it as high as 21mpg when I initially did the deckplate and ISR, and I'm hopeful that the seafoam will improve it again along with an AMSOIL air filter and thorough cleaning of the throttle body and MAF. Perhaps with a complete going-through of the motor, I can hit the magical 23mpg mark. With non-leadfoot highway driving a couple weeks ago I did see almost 20...

 

just did the 1/3 can into the pcv hose and the rest into the gas tank this afternoon. smoked a bit. I'll see how it works out on my 2 day road trip. the engine sure runs quieter and smoother, I haven't noticed that it did away with the cranking hesitation though, maybe after the treated fuel runs through it will start faster.

 

Anyone tried this with an older Runner? ('87 SR5 EFI)

 

I noticed an *instant* start with the K&N removed, and a second or two of cranking as normal with it in there regardless of it being cleaned or not. Going to clean the MAF and throttle bodies and drop a new filter in to see if that helps. Seems like that hesitation might have to do with airflow.

 

i got an *instant* start after doing the seafoam to the intake. maybe it was the dirty intake...

 

Should work fine and the same way. Just note the numerous and heavily emphasized statements about pouring it slowly and carefully so that you don't hydrolock the sucker.

 

You know ... it'd be cool to see some sort of nipple with a hose attached PRE-throttle body. Seems like that would help clean out the TB too, wouldn't it? Or would that be a bad idea?

Comments welcome.

 

mine has two nipples on the top of the throttle body that are capped off. when I would use regular TB cleaner I would stick the red straw in one of them and spray while the engine was running. You could probably do the seafoam the same way, I thought about that but since nobody else had tried it I wasn't going to be the guinny pig.

I took a 3/8" vacuum hose and jammed it into the ID of the PCV hose for an extension and ssat the cup I put the seafoam in on my bumper so I could see when it got to 1/3 of the volume.

 

I'm stumped. I want to do the seafoam tonight, but dont want to do it wrong. I guess I could do the brake booster hose. Which is better? PCV or brake booster hose? here's a pic, someone tell me where the PCV is! I've got other ones from other angles if I'm looking in the wrong place!

 

or?

 

Nevermind, I found it. It's the one right below the hose that has 3 little hoses coming from it. I pulled the hose off, attached another hose to it, and sucked in some seafoam. It smoked some, but nothing crazy. I'm letting it sit right now, and I'll give it a 2nd treatment if it needs it.

 

funny, Adam, you are the one I would have thought knew where the pcv valve was. hehe.

I just got to Greenville tonight and 4 tanks of gas my average mpg after ONLY the injector cleaning and dumping 1 & 2/3's cans into the gas tank is around 16 mpg! BEFORE the treatment it was 13-14! I would say this is a pretty good thing to do.

Plus I noticed the engine ran better, quieter, smoother and no more valve noise!
