Ive been serching and serching the forum about topics on that sea foam stuff. Almost every post i read says it works wonders, but theres always some one that claims its bad and a week later there engine goes. Now i like the idea of seafoam, but im worried of what would happen if i treated my engine with the stuff, My car has 147,360 mile on it, what do you guys think?

 

just for basic clean up, go for it man, it works wonders, you'll notice the difference right away. my car feels like it pulls harder, and idles more evenly when i do it.

i've only heard bad things if you leave it for long periods of time, like weeks. my other theory as to what could go wrong is (and someone with more knowledge can prove me wrong) that after seafoam does its job, it cleans up carbon that's built up, maybe covering a crack/tear on a seal or something, so when it takes the carbon away there's nothing to cover the crack, but that's just my theory. may be true for coolant leaks, maybe oil leaks idk. and the way i see it, if it had a crack/tear it was just a matter of time for it to give you trouble anyways.

 

+1 on seafoam being AWESOME. I use it about once a month, and my idle smooths way out. Just gotta watch for cranky neighbors or cops rolling by whenever you dump it down the carb because the smoke will be thick and last about 5 minutes

 

seafoam is alright but like the second poster said it can cause problems. i used it in my awd turbo talon and i had 90k on the dash and it cleaned it out good but also cleaned up my seals and then i blew a head gasket.

 

Put it in the gas tank. You'll be fine...

 

no joke, now thats a smoke show, best done on a windy day
i dont use it that much but when i do its great, 1/2 into the carb directly, the other half in the tank

 

if you're pouring it down the carb put a little at a time, if you put too much it'll foul a plug, ask me how i know.

 

I've never heard or read of a seafoam horror story. I've seen and experianced automatic transmission fluid horror story but not seafoam. I think you need to search this forum not hondatech.

 

Alright, here's my "opinion" on the whole smoke show scenario:

That huge cloud of smoke you get when you dump Seafoam down the carb, or suck it in through a vacuum line, is nothing but wasted product going out your tailpipe. Again, in my opinion, adding it to the gas tank and going for a spin is the best use of this stuff, and will avoid a lot of the issues people seem to have every once in a blue moon....

Don't make it any more complicated than it needs to be.

 

^+1 seems like this topic gets covered atleast once a month. i've done it both ways sometimes i just pour it down the carb just to hit the inside of the carb pretty good, but then i put it in the gas tank, either way works fine, but if you put it in the gas tank it'll also clean your fuel lines.

 

ok ill take your word's for it. Ima give it a try. On top of that Im going to give my car a tune up, oil filter, plugs, fuel filter, oil change, transmisson oil, collant flush,..... the hole bit. Should i do this after or before the sea foam?

 

after seafoam treatment, that way all the **** it loosens up is taken away with the filters

 

The only real problem I can see with using seafoam in your engine is as it has been mentioned before.

Those lovely horror stories of, "I changed the fluid/cleaned up the oil/cylinder/rotor and it suddenly started leaking and blew a gasket.

Basically, like it was stated, on some engines that are not well maintaned and even those that are, that gunk is actually holding the engine together. Go figure.

But in my personal opinion I have never had a problem with Seafoam, I run it in my +100k 1993 Chevy Blazer, the 1990 LS400 with about 150k on it and when I still had my RX7 the 12A with almost 250k miles on it.

So I say just do it and enjoy the rewards!

 

Which is why I never recommend adding a cleaning agent to the oil. A lot of times it is only the sludge buildup on the oil seals that is creating a good seal. Clean all of that out, and all of a sudden the seals start leaking and you start burning oil....

I really don't think there is much risk putting it in with the gas, because varnish only cloggs **** up, and carbon on the apex seals restricts their movement and causes a loss of compression.

 

I've never actually used it in my oil before... O.o

 

I agree with Kentetsu if you are worried about the miles on the car or how the P.O took care of the car put it in the gas tank you will get the same results with out the need to stress over it just my 2 cents worth I have used seafoam once a month on my cars no problem and even put it directlly in to the rotars on my sons 79 because the motor was carbon locked when we got it solved the problem and the car started right up no problems and is still running strong

 

Sound good thanks for the advice. I will seafoam her this sunday and ill keep you guys posted on what happens! thank you
