Dont tell me to use the god damn search button. I have read what I believe to be every thread possible on this forum and I still have not found a response regarding this stuff after being run on a 3rd gen.


Has anyone with a 3rd gen used sea foam to clean the carbon build up from their engine? My primary reason for asking is due to the fact that my engine is currently running pig rich from the PFC base map. Also, the original owner was driving the car with the sequential system all botched up (which I fixed) and I believe there is excessive buildup in engine.

I do routine redlines for the engine to puff out any loose carbon but I would like to consider doing a good deep clean of the internals.

I do not intend to do it into the crank case, via a UIM nipple but instead through the fuel tank. I want to do it through the fuel so I can clean up my injectors in the process.

HAS ANYONE RUN SEA FOAM ON THEIR 3rd GEN THAT CAN POST ANY POSITIVE OR NEGATIVE RESULTS?

I would do this first...

I *have* done it, several times, and it's perfectly safe.

Well I have used it once definitely made an improvement. I'm also running a pig rich pfc map and getting tuned this week so as soon as my tune is done sea foam is going in thats for sure.

Can you tell me your experiences with using it and what method you used? Also, why would you do it after tuning your car? Shouldnt you sea foam, do an oil change, replace spark plugs and then get the car tuned immediately after?

Why would you tune your car with possibly semi fouled plugs and carbon filled housings??

Anyone else have experience with this ****, I really want to put some in my gas tank but I dont wana be crying 1000 miles down the road with a coolant seal failure on my hands.

The carbon is going to blow out anyways (Dyno runs!). It's a street ported motor and I already changed the plugs and and oil today

The sea foam I'm using to clean up any access residuals.

i watched a guy run too much sea foam in at one time and it hydro-locked his mr2. I would not use sea foam, but you can use top engine cleaner, it goes in as a spray foam, not as a liquid... its safer and does the same thing.

The Driver

iTrader: (4)

Btw ~ I ran mine through the gas tank

I think it would be almost impossible to hydro lock the rotary engine (by feeding sea foam in to the engine through a UIM nipple)
But FD3Smaniac, I appreciate your recommendation regarding the top engine cleaner.

For future readers....


I DONT CARE WHAT YOU WATCHED YOUR FRIENDS DO GUYS, IF YOU HAVE NOT USED SEA FOAM ON YOUR OWN CAR AND YOU DO NOT HAVE A PERSONAL EXPERIENCE USING THIS PRODUCT ON YOUR CAR DO NOT POST.... I WENT THROUGH COUNTLESS THREADS OF PEOPLE SPECULATING WHAT MAY OR MAY NOT HAPPEN, I WANT TO HEAR TESTIMONIALS FROM PEOPLE THAT HAVE USED THIS PRODUCT... ROOARRR!!!

i currently pour a can in the gas tank every once in a while and at the same time do water cleaning at the uim nipples, maybe every other oil change. I dont notice anything good or bad.

i'd never do it in the oil because too much stays in the engine after oil changes and I worry it would damage something...

I've used Seafoam in my car. I don't really know whether it was positive or negative. The car didn't seem to run any different after I did it, but I did find out that I had an exhaust leak at the turbos by using Seafoam. Here's the link of me using it.

http://www.youtube.com/watch?v=vTGmX4Fxg8Q

No, it didn't clean up my emissions to help me pass the sniffer, but then again, I got lazy and probably should've changed out the spark plugs right before the smog test. When I finally did change my plugs, they were filthy. So I'd probably recommend you change your plugs after use Seafoam.

First of all your welcome for the recommendation. Second of all.... calm down killer, i was giving you a little tip. I know your not going to hydro-lock but pure liquid in the engine isn't a good thing in case you didn't know that. you know when you ask for experience and someone gives you an experience of theirs dont bitch about it. Also who the **** are you to tell me not to post. Good day to you sir

















nah... im just messing around.. but for real... thats a real experience, i was there, and **** happens, it can put pure liquid in there. all im saying is top engine cleaner is safer, and i have used both, they both work the same.

Let me rephrase my statement of intent regarding this thread...

As FD3Smaniac has brought it to my attention, there is more than one option to clean the internals on this engine. From my recent forum digging endeavor, it would seem that ATF, Sea Foam, Water and good old fashioned high rpms are all solutions.

Rather than to constrain my self to one method, that being sea foam --- I would love to hear about other alternatives and personal experiences.

If anyone on this forum happens to read this; if you have done a procedure to clean your internals (injector build up, carbon build up etc.), will you please specify?

Please state what product you used, whether it be atf, water / **** (what ever your remedy is), the method you used to deliver the product into the engine (vaccume lines, oil, fuel etc) and what your post results were at X amount of miles as well as personal impressions / data to support it.

I personally, am very intrigued by this sea foam procedure and have heard very mixed opinions on both sides of the argument, both equally valid in their own regards.

To my understanding, the properties of Sea Foam are coercive and and pose as a possible treat when in the engine by "ballooning" the seals which initially produces "noticeable" positive results in compression / power but long term, when the seals dry they actually accelerate compression or water coolant seal issues. (This directional hypothesis seems to be more supported by those who are against administering the detergent via an oil change where the user leaves the product in for extended periods of time)

This argument without a doubt holds a valid point when considering the fact that sea foam is mean to remove any oil / residue build up in the engine (including the good oil / lubricants that help reduce friction), as well as the fact that it's properties may be detrimental to the seals.

On the flip side, I have read a few various posts by individuals who said they had fantastic results using this method with no long term side effects (that could be directly related to this product and method of delivery).

My biggest issue and concern is that, while there is a pretty extensive history of this product being used on FB's and FC's --- there does not seem to be enough supporting evidence in the 3rd gen section to help me make my decision on whether or not to use this product.

If I do end up using it, I intend to administer it via the fuel tank with 1/4 tank of gas followed by an oil change.

I do not plan to use this product for at least another 2,000 miles as I am currently doing my own personal experiment regarding ZDDplus.

I already did a pre compression test, and I have to do a test every 200 miles till I hit my 2000 mile mark --- so clearly, I have to wait on any kind of carbon cleaning product until I finish this in order to avoid any possibility of a confounding variables that my interfere with my ZDDplus experiment.

Please when you use... whatever you use.. post your thoughts. Since there isnt much (like you said)... there isn't much information on this topic. I used Top engine cleaner on my car, It dramatically reduced my CO's and HC's on the 5 gas analyzer. And for those that dont know what HC's and CO's are its hydrocarbons and carbon monoxide which is unburnt and partially burnt fuel. If you have a chance to get some sort of emissions readings, Even a difference in AFR it would be great. Id like to see the results of this.

I'm also interested in this. Like spoolage, I once did a search on Sea Foam and read every post. It was confusing. What is Top engine cleaner and how is it used or how did you use it.

Spoolage: I have done a water treatment by running 2 liters of water through the engine via a vacuum line connected to a nipple on the UIM. Worked fine, produced lots of smoke, no noticeable effect on the engine for good or ill. I'm also considering using Sea Foam in the fuel, but like you, I am a bit reticent. I actually have a bottle of it sitting in the garage waiting for me to make a decision.

I have used seafoam on several different kinds of cars. I know that you dont want to hear about people who havent actually used it them selves. The only thing i'm guilty of is not using it on a rotary. But heres the deal. On 3 cars i was using it to clean up carbon deposits on valve surfaces. It did nothing. On another car i used it to try to clean off carbon from some nasty looking pistons. P.s. i have a borescope that allows me to actually see these things in fully assembled engines. It did nothing. Lastly i have tried using it to free up a stuck oil control ring on a piston. It did, get this, nothing. My conclusion is that seafoam is pretty much garbage. It makes a fucktruck of smoke that smells like death and does basically nothing. Useless. I have however used the water method on a couple of different kinds of engines and guess what, it worked great and cost basically nothing. Seafoam is stupid. I think its supposed to be used as some kind of cockamamy routine maintenance. Seems crazy to me. Here put this crap in your car that makes the biggest smoke cloud you have ever seen and do it every 10 to 15k or so. Yeah right. die seafoam.

Oh and top engine clean is gm's version of seafoam. If gm bought into this crap they are as dumb as i thought. Which is pretty much as dumb as having a Cadillac commercial with a guy saying if his escalade had a toilet in it he would live in it....wait that actually happened...seriously.

when doing the water method, I assume you want to use warm, distiller water? I think water sounds promising and will not foul my plugs or eat the seals during the process. I just KNOW my engine has significant carbon build up, I can smell it with my own nose. I believe the previous owner has been driving the car a substantial number if miles on a semi clogged down pipe. Before I replaced the downpipe I was having semi cooling issues as monitered via PFC and water temp gauge (pre and post thermostat) temps would not stay below 95c and would quickly reach 105 Celsius. Since I pulled the dp, temps never go above 85 when crusing or idiling. Gota clean her out now

I don't think the water needs to be warm. I just ran a vacuum line from a 2 liter bottle that was sitting on the ground. By the time the water goes through that small vacuum line, up to and across the engine bay, and then into the UIM, the water is going to be a bit warm anyway. Besides, the volume is really low so it could probably be ice cold and not cause a problem.

Putting Sea Foam in the fuel to help possibly clean the injectors is something that I'd like to hear about from folks.

I am changing all my fluids today, I may add some sea foam to the gas tank... Will log my car pre and post.

Okay guys... so here is my story and reason for considering an engine cleaning procedure. In a nut shell, I bought the car about a month ago, the car had a reman installed with what is now approx: 16k miles. The secondary turbo was not working due to a vacuum leak which the seller I believed had mistaken for what he had told me was a slipping clutch. Due to the nature of how the secondary turbo would spool up intermittently I could see how somone would easily mistake it for a clutch that is beginning to slip. On top of that, the car had a clogged ndownpipe that was causing considerable water temp issues. It was at this point, and after inspecting the sparkplugs, that I decided the engine could use a good internal combustion cleaning.

On to my little experiment, so far I am finished with phase one...

I did two compression tests today, both were done on a warm engine approx 10 to 15 minutes after shut down...


These were my base line compression tests: (Oil has approx 2,500 miles of use)
-Test 1: Rear rotor 101 psi, Front rotor 106 psi (Vacuum 17 inches)
-Test 2: Rear rotor 100 psi, Front rotor 108 psi (Vacuum 17 inches)

Following the base line readings, I did a steam clean of the engine. I decided to go with the steam cleaning method versus sea foam primarily due to the fact that I have not read enough testimonials / experiences with this product and its effects on the engine long term.

My steam cleaning method was as follows: I used half a gallon of distilled water that was hooked up to the nipple on the UIM that runs to the pressure release valve (the black OEM bov). With my friend holding the jug of water and me in the drivers seat, he dropped the vacuum line and instantly the RPMS on the car will drop and the car will nearly stall (I kept the RPMS @ around 4k, periodically redlining the motor.) I did this until there was no more water left in the jug and kept revving the engine for roughly 10 more minutes.

I let the car idle and it seemed stable so I shut the car down, let it cool for 15 minutes and did my second compression test.

These were the compression numbers and vaccume following the Steam cleaning method.
-Test 1: Rear rotor 111 psi, Front rotor 120 psi (Vacuum 19 inches)
-Test 2: Rear rotor 110 psi, Front rotor 120 psi (Vacuum 19 inches) - This was done an hour after the initial compression test

So... following the steam cleaning method, the compression on both rotors increased by a minimum of 10 psi and the vacuum increased by 2 inches.

Following this process, I changed my oil with the usual royal purple 20w40 but I added a little twist (ZDDplus) addative...

I will be doing another compression test in 500 miles...

wow....seems interesting

might have to give my baby a lil steam clean as well

crazy... never thought of a steam clean.. i mean if its going slow through the vacuum line like that its going to vaporize before it gets into the combustion area. Great idea and good results. I wonder if there would be a difference now at this point if you were to use the seafoam or top engine cleaner. i guess to kind of get an idea how much the steam cleaning did, if either of the products work for you at all.

that thread is pretty much all the details on steam cleaning.

i say use 2:1 sea foam and water and a last run with 2L straight water.
