Disclaimer: Using Seafoam wrong will mess up your car. Use with caution and at your own risk. My DIY is a quick guide but read the seafoam instructions and follow them carefully.

1) Find the brake booster line (outlined in yellow). I disconnected mine near the actually intake manifold instead of at the break booster (I circled two points, just use whichever is easier).

2) I pre-poured about 1/3 of the pint of Seafoam into a disposable plastic cup.
3) I started the car and then slowly let the brake line suck in the seafoam from my plastic cup. I poured very slow. Took about 1:30 - 2 minutes for me to drain the cup.
4) When all the seafoam is gone turn off your engine.
5) Wait 5 minutes
6) Turn car back on and drive around for a couple of minutes. If your car is really dirty, you'll have nasty black clouds coming form your exhaust. With 50k miles on my car, I didn't see anything. Guess that's a good thing, just not very satisfying. My friends old crappy Oldsmobile probably put a hole in the O-Zone layer on its own.

 

Very nice. I did this on my old prelude once, I got black/grey/white smoke for about 15 minutes... pretty satisfying.

 

thanks for the DIY!!
I'm guessing that you only do seafoam when u hit like 100,000 k r somethin like that?

 

^ yah, i was also wondering when should seafoam be done?

 

You really don't need this stuff if the car is properly maintained. The same applies to fuel additive, oil treatment, snake oil. etc.

 

Save your money for gas.

 

i did seafoam when i hit 50k miles and nothing came out.

i only changed the oil 10k mile interval and that was with conventional oil.

my guess is, tsx doesn't really need seafoam.

but on the other hand, my friend's 325ci also did substantial damage to the ozone layer.


btw, don't you need someone to keep their foot on the gas while pouring seafoam?

 

No. That is why the OP used the cup. To control the flow. Use the sip sip method. In other words, just let the hose sip it in, a little at a time. If your car sounds like it's going to stall, just stop the sipping for a second. When idle returns to normal, continue the sipping. I did mine (on TL-S) by myself and it took about 5 minutes or so to empty the cup.

 

Hi,

Do we need to attach another tube to the brake booster line whose other end will be put in a cup which has seafoam ??

If so what should be the diameter of the tube that's required.

thanks

 

no tubes or additional parts required....
pour 1/3 into oil
pour 1/3 into gas tank
disconnect your vacuum hose thats connected to the front of your intake manifold.... not right at the L piece where it connects to the IM but up higher.... GENTLY pour little by little 1/3 of the seafoam into this hose while your car is running....

you will know right away when your pouring too fast because your car will sorta studder and wanna stall out on you, slow is key, little by little it will suck it all down....

once done with those 3 steps.... rev it up to 3000k and until the smoke starts going away.... then your all done

its best to do seafoam before a long drive, you DO NOT want to put this into your car and let it sit.... this will damage o rings and gaskets.... put it in, wait til smoke goes away for the most part, and take it for a nice cruise

 

Hi winndogg34,

Thanks for your response..

I used seafoam during the weekend and it was really easy..thanks for nice instructions..

I have put 1/3 of the can in the crank shaft . I read some where that i need to go for an oil change with in 100 miles. Is it true ??

I am at least 2000 miles away from my next oil change..

I have poured 1/3 of the bottle in the gas tank and used a plastic cup to pour into the vaccum line..

I stopped the car sit it idle for 5 min and revved it to 4k, 5k rmp and i saw good amount of smoke ( not a lot but noticeable amount)

And now i notice the difference when driving. The response is much better now..

How often do you guys use seafoam..

thanks..

 

Yes, you should change the oil soon because it thins the oil.
You do not need to Seafoam regularly. On my previous car, I did it at 100k intervals.

 

thanks a lot for the info psteng19..

 

Would you replace the spark plugs before or after doing the seafoam?

thanks

 

after

 

thanks

 

Hi,

I've been reading your thread, thanks for the useful info. but i have one Question: is it absolutely necessary to change the spark plugs after doing seafoam on your car?

thanks
