So, I decided to seafoam my old 96 with almost 200,000 miles on it...

This question plus another, excuse my ignorance. Based on the description below, is this different than using a throttle body spray and cleaning the throttle body? Then two, if you remove the air intake won't the engine die on you? Go easy on me, it is an honest (stupid) question for learning.

Oh and one more, is this to achieve the same results as using the fuel additive, just a more direct and more effective path?

 

You did something wrong. I don't think any of that "soot" had and thing to do with the seafoam. Every time I seafoam something all I have to do is turn it on and let it idle, it blows white smoke like crazy without me bouncing the motor off the rev limit.

 

No don't put TB cleaner in there. The seafoam has stuff in it that breaks down all the nasty shit that builds up in your engine over time. And to feed it to your motor make sure you use a hose that feeds all 4 cylinders

 

ok we seen to be bouncing around here, over time all motors produce soot. keeping the motor tuned as much as possible will reduce this. that is why its best to seafoam and then get on the highway and really run it.

my great, great aunt drove till she was 96, I-85 cut right through her property, so after a slight heart attack when she was 89, NC banned her from I-85, they did not figure she would cut accross us 70 to I-77 and keep going. she liked to get on the highway to blow the soot out of her 1977 Catalina.

with high miles it can never hurt to do a throttle body cleaning, good chance to do the idle air valve on the side, they all get dirty over time.

google Toyota catalytic coverter cleaning, there is some interesting things to be found.

remember today's e-10 gas is compounding the problem of engine soot.
check my pics of my o2 sensors i replaced last year, they were coated. worst i have ever seen, and they had yet to throw a code. but the truck ran much better with fresh ones on.

 

You use TB cleaner to actually CLEAN the throttle plate and throttle body. It has NOTHING to do with cleaning out valves and combustion chambers and all that. You don't run TB cleaner through your engine, you just spray it on the throttle plate so you can wipe off the grime.

Seafoam is meant to be ran through your engine and combusted. It cleans everything from behind the Throttle plate (or wherever you introduce it) out through the exhaust.

No need to run your vehicle when you clean your throttle body, but you do need to run it when you seafoam it.

Seafoam is good for finding exhaust leaks. We found a ton on that little red Taco and my buddy's Celica.

 

My question seemed to be overlooked.
My truck is not currently in need of an oil change or new plugs, can I Seafoam it now or do I HAVE to change the spark plugs right after? A friend of mine said you don't have to but I've also heard that you do have to. Thanks

 

Easier to use the brake booster .

Yes, but dont use SEAFOAM to clean your TB unless you follow up with a degreaser or some sort. TB cleaner is designed to evaporate cleanly, SEAFOAM will just make it oily and it will just get dirty again.

Usually do the SEAFOAM right before oil change. You can pour SEAFOAM into your oil too to clean the sump and shit but dont drive more than a few miles on that (some say up to 500 is ok).

SEAFOAM will still contaminate your oil a bit, even if you put it directly in your engine which is why I wait until its time for a change. Not sure about spark plugs, I would think though that SEAFOAM does the oposite and cleans them as well .

 

I did not change my spark plugs and mine ran just fine for another 70k+

 

Thanks guys!

 

Nope. It has been confirmed that the brake booster line only leads to ONE cylinder.
