Seafoam DIY!!

I believe you can also use the PCV hose. Don't know how the RX's engine is setup though. So I don't know if it will get into every nook & cranny of the engine.

Another believer here. I managed to do it by myself, though. I pre-poured the seafoam and used the PCV valve hose. First, I loosened the hose and loosely re-connected it. Then, I got my garage broom and placed it on the started vehicle's accelerator pedal braced against the back of my driver's seat. I used the forward motor control on the power seat to bring idle at to 2,500 rpm and hold it there. Let the motor suck in the seafoam and did a quick shut down. Was amazed at how much smoke came out after letting it sit for twenty minutes. Subjective observations concur that idle and acceleration are smoother, and also there is marked oomph off the line acceleration via seat of pants dyno.

I must say this is very interesting,
Although I am skeptic. Im with the fello that suggested doing it twice and seeing if the smoke amount is the same, hence proving how much of the smoke is carbon and how much is the seafoam burning.
I personaly have never even heard of this stuff until now.
Must be an American thing. I can't find the stuff in Australia.
Probley just carby cleaner with a fancy (well not so fancy "Seafoam" HAHA) name.
I really dont like the idea of putting this stuff in your oil. Sounds very dodgy. This would change the viscosity of the oil.
Another thing is, Improved idle?? we are talking about a 1UZ, do you get any smoother hahahaha.

If not for anything else, the size of the cloud is an impressive spectacle.

hahahaha if you want smoke, next time you do your oil change, instead of disposing of that nasty black oil, just recycle it. straight into the fuel tank!!
the say hello to smoke ville (great prank to play on people)
So where do you guys purchase this seafoam, just from your adverage auto parts store? Is it an American Product? Any Idea if its paitented? as I have never heard of anything like this in australia even a cheap knock-off (I did a google search on australian sites and it just came up with stuff about sea polution and creating beach foam LOL)
I am interested to know more, but the more I learn the more im skeptic hahaha

SeaFoam usage
An update on the SeaFoam usage attempting to fix my idle issue.
Background recap:
After a steady drive for ~ 2 hours or less on the highway followed by a quick stop at the rest station my idle, coming to a rolling stop, went down too low causing the engine to stall….
Although it started right up, the issue got worst with time .. the dealer could not find a thing wrong and the engine light never came on…. Once the dealer conducted the injector cleaning process (for about $100) the problem went away ‘till about 6 to 8 month….
I used the SeaFoam 3 times with an interval of ~ 300 Miles through the Booster Break-line etc… and twice in the fuel tank, each ½ can for a ¼ tank.
Results:
I drove up north in one shot 3 hours in one stroke and back…. Came to a rolling stop and the idle was normal…. No stall, car behaved as expected or same as when I got it back from the dealer post injector cleaning.
In fact, I back calculated the fuel consumptions and gained about 2.5 miles to the gallon.
All-in all, fact findings could suggest that I have corrected or found the root cause (carbon build-up) of my idle issue.
Next task:
Establish the overall interval on SeaFoam cleaning process… i.e. mileage in-between cleaning.

Where did you let the seafoam go? Did you put it in the intake on in the valve cover? If it went in the valve cover, you may want to change your oil.

What bothers me the most the dealer ship was NO help… yet they keep track in a database of all repairs and issues… on the databases are connected within the US.

I believe it is number 2. That should be going into your brake booster.
Pull it off and your idle should fluctuate. Put your thumb over it and it should have suction. If it does, it is the one.
I'm not a mechanic, but thats how I do it.

hey guys, a little heads up... if u plan to seafoam ur fuel system via. fuel tank side, i suggest u pick up a new fuel filter as well. walmart has the fram ones, or u can go to redline, napa, checkers, dealer, etc. reason is, the seafoam will break up and clean all that gunk in the fuel lines. guess where all that funky stuff goes? yup, the filter. might as well change it since it's not that hard and will free up the fuel flow. there's a write up on LexLS.com, or if u have a service manual u can use that too. happy foaming
