Seafoaming...Whos Done It?

[NismoGizmos]

My friend and I a couple weeks ago were changing the spark plugs on my Z...when we were all finished he asked me if I had ever seafoamed my Z...I said I had never heard of it. So I figured I would go ahead and do it. I posted some videos on youtube of it. I was wondering if anyone else has done this to their Z

I have 2 links:

That one is right after we seafoamed

And this one is after most of the smoke was gone!

did you notice a difference? I've heard good things from people that have done this before.

[NismoGizmos]

Honestly I thought at first it was the whole placebo effect (It costs money therefor it must work). But actually I noticed the car sounds and runs smoother...not a night and day difference but it is mildly noticable. I would say its worth it (1 can is around 6 or 7 bucks). You have to be careful when you feed the seafoam into the brake booster hose though because if you suck it through to fast you can risk hydrolocking.

[tollboothwilley]

I've never run it because I don't know which hose to run it in through...

I've heard it helps smooth out the idle.

if you keep your oil changed and run quality gas you have no need of such products

[PapaSmurf2k3]

...and you are supposed to run it BEFORE you change your plugs. For a complete seafoam job, you run it, then change your plugs and O2 sensors.

Usually it doesn't need to be run on anything with less than 80k on the clock.

[rmezz13]

what are some long term effects of this? doesn't sound like its good? what is it exactly (i've never heard of it).

[evildky]

seafoam is a chemical cleaner, It smells very familiar I just can't figure otu what exatly it is, you put some in your oil to clean all the built up gunk form not changing your oil, and you put some in your gas to clean injectors from cheap gas and some in your intake by way of a vac line to clean deposits in the intake and on the valves form not changing your air filter

if you actually take care of your car, it's not needed, my abused 200k mile Z32 engine, and 183k mile l28ET which came fomr a junkyard had no deposits that needed cleaning

mostly it's doing nothign while making you feel like you are doing something

[PapaSmurf2k3]

eh, that isn't entirely true. My intake manifold (on my 240) after the throttle body was pretty gummed up with carbon and other ****. This was NOT from a dirty air filter... everything before the throttle body was clean as a whistle. Sometimes you just get backfires and other crap which can build up carbon before the combustion chamber, in the combustion chamber, and after. Seafoaming through the brake booster helps to clean that crap out.

FYI, I think running it through your gas tank is BS, but through the brake booster and oil is definitely useful, just don't keep it in the oil for very long at all (like 15 mins max).

[MySXisSlowerThanUrs]

Put this in my Mr.2 And it seemed to Idle better and it somehow felt smoother in the RPM range... But i recommend this. I dont think its all that necessary on a Newer Z but you can always try, It deff wont hurt anything

[BusyBadger]

what is it exactly (i've never heard of it).

When Google is down Yahoo! is a reasonable substitute. Seafoam There is a pdf MSDS sheet on there for those that want to try and reverse engineer the alchemy behind it, or just want to figure out what the familiar smell is.

It seems to be much more popular (in my experience) with S13 drivers than any other Nissan crowd. But I probably have a slanted view based on my vehicles of choice. Seafoam did get a big boost in popularity a few years back when Phase2 used it when building an all-motor KA S13 and posted the process on their website.

I considered doing it when I was in Chicago and always driving stop & go (on an 250K mile KADE) and was having some idle problems that didn't go away after the typical IACV & vacuum hose checks. Now that I'm in TN and make longer drives the engine seems to have "self-regulated". I'm sure that the milder temps play a large part too. No idea about what long term issues, if any there may be. But if its done properly I can't imagine needing to ever do it more than once on an engine that's properly maintained. I also can't imagine that the OP's engine needed it either, but to each his own.

IF you wanna seafoam your car here is the proper way to do it.1. take seafoam pour 1/4 can in gas tank.2. pour 1/4 can into oil fill.3. start car and have someone give it slight gas disconnect vacuum line going to the brake booster and use it to suck up 1/4-2/4 of the can (do not submerge hose in liquid).4. turn car off let sit 5 mins or so drive car till no more smoke comes out.5. immediately after flush oil then change it change your spark plugs and o2 sensors.(you can skip step one if you want it cleans out the crap in your fuel tank if you do step once change fuel filter after.)

question #2. If you change your plugs, O2's, fuel filter, and oil then WTF is the point of that stuff? Of course its going to run sweet if you change all that at once... I bet it is a mind game and is just something that makes your car smoke white (because your sucking in water) sounds to me like a joke. Anyone wasting money on this is retarded. I want to see a before and after of the effects of this stuff (and not from their ad website). Sounds like

its like

[R350Zz33]

well seafoam is really for marine engines if helps to burn up all the carbon deposits left behind thats why people run it in old engines the clean all the carbon build up and sludge out of the motor you change the filters because now they are going to be filled with all the gunk you just got out.

[Beancooker]

I'll just stick with BG44K and the other BG products.

[PapaSmurf2k3]

Anyone wasting money on this is retarded.

I've done this about a dozen times (I've owned a lot of cars, and I used to work at a garage that we did this at). Once or twice, we had changed the plugs and O2 sensor before the seafoam, with little to no improvement. Put all the old crap back in, run the seafoam treatment, and then swap in the new O2 sensor and plugs again, and BAM, the car revs smoother, idles smoother, shudders less, etc..

don't knock it til you try it man.

[NissanFairladyZ32]

Have done it to many vehicles seems to work great i woouldent do it to a 350z with less then 60,000 on the odo ...

but like stated before if you change plugs, filters on time you really wont need this at it

( mostly for 100,XXX cars)

[RemixZ]

Every 6 MOS I Seafoam the oil with one can and drive under 4,000rpms for about 200miles , and BG44K the fuel with a full tank of racing gas and try to run a continuos 30 mins at 3,000rpms +. But its probabley snake oil...

Or

Drive your mom's or dad's or girlfriend's ect. slow *** car for about a week, and then drive your car. :P Or better yet drive my car...:-/

I'll just stick with BG44K and the other BG products.

[350z_drift]

i seen it around but always was spectacle about itnot many people seen using it

[phyzicxz]

seafoam? isnt that frog sperm?

[BrandAidDesignG35]

Uhh, yeah... I think so.
