Hi everyone,

i could really use some help. I want to do seafoam for my car. Its running sluggish and was thinking it could be the cad. Converter but im in ca. And they are very expensive and want to try a cheaper approach before i go out and assume its my cad. Any instructions on seafoam or receommendations would be very much appreciated.

Thanks!!

Welcome. But you can get some good info by just googling "how to seaform 95 honda civic.

JS,he has already tried that. I am a big fan of AZine and have been saved plenty headaches here and love and recommend this website like I have Acura and Honda cars to all my friends.

DMAC was reffered here by me after we looked online and found very different and questionable instructions on how to SeaFoam his model. Some said pour it straight into where you pour your oil and others say to use vacuum hoses and in more than one place so the only well informed place I could think of is here. Maybe if you could refer him to a link that has reputably verified results...?

Thanks

I know nothing about seafoaming, but there are a several DIY threads on AZ:

before i get into the seafoam steps, you mentioned you think your CAT is bad... do you have a CEL? normally if you have a bad cat, your exhaust should smell like rotten eggs and or the downstream O2 sensor should throw a CEL...

if you feel the car is sluggish (i.e... doesn't pull like it is supposed to) perhaps you have an exhaust leak somewhere which isn't giving you the normal backpressure required when you first step on the gas... i would check for these first before concluding that the cat needs to be replaced... esp since you already know an OEM replacement can run about 1k...

anyway,you should be using the seafoam in three places...

1) add to the gas tank to remove any moisture from the gas lines... this usually isn't necessary during the summer since it is more a concern of the water in the lines freezing during the winter time... and you live in CA anyway...

2) add to the oil crankcase a few hundred miles before an oil change... this is supposed to help clean the components in the valvetrain... in theory this shouldn't be necessary unless you don't keep up with proper oil change intervals or drive only a short amount of distances and the engine oil doesn't get up to full operating temps... this applies to me where i only drive the car to and from the train station that is 3 miles away...

3) suck the seafoam into the brake booster line or pvc valve... i usually pour the seafoam into a plastic cup and pull the pvc line... slowly put the pvc line in the cup of seafoam and let the vaccum suck in the product... the car will want to die if you drown the pvc so you can just hold the revs to keep it going... i do about half a bottle and then shut off the engine and let it sit for about 15-20 mins... then start the engine, you should have alot of white smoke pouring out of the exhaust, and go for a spirited drive down the highway to flush out any of the buildup... if you can't find the pvc, just get the brake booster line off of the firewall next to the brake master cylinder... and if the problem is the leak in the exhaust, as i initially mentioned, when you do this step, you will see the smoke spew from the point of the leak as well as the muffler...

i normally do all three of these steps when i do tune-ups as part of the maintenance... some people recommend that after doing the PVC seafoam, you should change your spark plugs but i never really had that problem...

Thanks for the tips and links. Very Helpful.

2 Questions for you KAMLUNG.... Just to be on the safe side, would you recommend I do an Oil Change... then SEAFOAM (and because the seafoam thins out the oil) do ANOTHER Oil Change after..?

the Other... I replaced my motor not too long ago and since then I've kept up with regular oil changes but i do not know the history of maintenance of the motor previous to when i purchased it and since it could have been sitting in a wharehouse for YEARS and there might be a chance of Build up, I average about 50 miles a day driving, would you recommend step 2 you suggested?
