So I seafoamed this new F22B1 I dropped in my dad's 94 Accord EX auto with engine running, I feel like it ran a bit sluggish than before but not bad though when you're driving it around. I don't think a person would notice this if they've never drove it before it was seafoamed. There's times when I keep the gas steady and tried to get it going faster, it'll somewhat jerk or choke a bit til you floor past that point. This all happens after I seafoamed the b*tch. Maybe my mind is just f*cking with me? But I know the jerk/choke is there for sure.

What I did was pour half can of Seafoam into the booster hose then the other half down the crankcase.

What I'll be doing is replace the spark plugs and see if it improves from there. I'mma be staying away from that sh*t from now on. FML!

Any of you guys experience this before?

I used it in my old F22 and my JDM H22. It worked fine, helped clear a few things out. I was told not to put it in the crank case, unless you do an oil change after. I just did it in the gas tank and intake manifold. Shouldn't make it worse unless you hydrolock the motor IMO

You put the wrong amount in - the can doesn't say to pour half of it in

You should allow the vacuum line to slowly suck up the Seafoam on its own. The engine will stumble a bit but shouldn't die on you. Let it sit for a bit then start it back up and hold the revs at like 2-3k IIRC. You probably should have only done one of those at a time too.

Yeah, I let the hose sucks it out on it's own slowly. Then I let it sit for 15 mins before I start her back up again.

lol there is a youtube video of a guy using it and gets instant rod knock lol. many reports of hydra lock also

jdmcertified909

people who dont know how to suck it in are the ones with rod knocks and hydrolock. not the product. its the morons who cant do things by the letter. also i did it to three of my cars. one even helped past smog after it had failed. one got egr code cleared never came back. better throttle response. fuel mileage. smoother idle. smoother engine.

djkurious

There it is.

nus_dogg

Yeah, I've used it before on two of my engines and never had this problem before. Engine right now idles and takes off smoothly. I think it's just my head that is f*cking with me.

Actually it says use 1/2 to 1/3 can and to rev to 2000 rpms while doing it.

When done let sit for atleast 10 minutes then restart and drive aggresively for 2-5 miles.

Either the plugs are foul or the cats clogged. I can start hearing rattle from my exhaust and this didn't happen before. A day ago, I just installed an OEM intermediate pipe with a new axle back as well. Everything was solid underneath this morning when I checked. So it's gotta be inside the cat converter that is making the noise.

I built a system for doing this after a teacher showed me some old contraption that they used back in the 90's. It has a container that is used as a resevior that goes to a ball valve through 5/8 hose (is I remember correctly just what ever size the nipple on the resevior is) through a ball valve, to a reducer to fish pump air line, a T fitting with one side open to atmosphere, then to a adapter that you can get from harbor freight.. (they come in the fuel pump, vac gauge kit) ... You want the T to be open to atmosphere so the the fluid can atomize before entering the intake manifold. Having the fluid atomize (become a mist) then you have less of a chance to hydro lock the motor...

This set up has worked very well for me for the past 4 years... Sorry its so long I and not very well written but I dont have a picture to show....

I also like to use a vac line as close to the throttle body as possible otherwise its more often just going to go into the runners closest to the nipple that u use.

If used correctly seafoam is a good product. I only use it right before a scheduled oil change so I can make sure that I have fresh oil in afterwards. There is always a possibility of washing down the cylinder walls and contaminating oil when using any product strong enough to clean fuel injectors etc.

This whole Seafoam thing strikes me as so much huile de serpent, to say the very least.

Running Seafoam directly into the intake won't do anything (good or bad) for fuel injectors, and unless the engine is already on its last legs and headed for the scrap-heap or the rebuilder's shop, it won't do anything good for the intake ports, the valves, or the cylinders and pistons.

Running Seafoam through the fuel system is highly unlikely to do anything good for the injectors either. Why? Because modern fuels keep fuel injectors and the zone where they spray into the intake ports so clean that dirt couldn't be found even if a microscope was employed in the search.

So what's the point of using it; to see a plume of smoke come from the exhaust system?

nus_dogg

Pretty much.

Anyways, this is what I found when I pulled the plugs out to inspect:



The center electrodes are gone! Hope to solve the issue by replacing them.

what is this hydralock?




i only know about hydrolock

Hydralock:

When the jaws and teeth of two or more of the Hydra's heads gets fully engaged with the sorry hind parts of some hapless wanderer. :p

Have you ever taken one of these 18-15 year old F22B1/2 engines apart?

I can tell you that the modern fuel injection doesn't do much to keep anything clean. Specially if the owner of the car never does any regular maintenance. I've seen some pretty gummed up F22 injectors in the past few years.....

The product works as described when used properly...... Thing is, you also have to do a few oil filter and fluid changes to help clean out any carbon/gunk that has been loosened up.

Used this product for many years and never had any issues with it. It works for me!

GhostAccord

Those look like they have been toast for quite some time. Now is definitely a good time to replace them.

shipo

You'll have to forgive me but I'm the consummate cynic...

Please tell me what "regular maintenance" will prevent what you describe.

FWIW, I've torn down more engines than I care to count, and to date I've never seen a single intake where the injector and the spray zone weren't so spotless that if I'd pulled them apart on a very sunny day I'd need sunglasses to keep from blinding myself by the reflected sunlight.

Now, if the engine is neglected and ever increasing amounts of murky combustion blow by build up in the area of the intake upstream of the injectors, then yeah, Seafoam may be useful in cleaning out the upper regions of the intake track. The same cannot be said for the injectors; they should be spotless regardless.

GhostAccord

We are talking about 18 year old engines here...... So what you have described above is what I am talking about...... no the seafoam does not clean the pintle of the injector, I agree that they are usually spotless. However, I have found that putting it through the fuel system helps clean up the backs of the intake valves and the combustion chamber. Using that method along with putting it in the PCV port on these particular intakes aides in cleaning the carbon from the CC of a neglected engine.

nus_dogg

Yup. Got a new set like these put in today and man, no more stumbling/hesitation on acceleration.
