Please someone talk to me about seafoam in the old gal. do I pour it in the gas,run it for fifteen min and then let it set a while then what. ?

bugman1973

go to the search function and look up sea foam check there first. people ask about that all the time. i personally dont know how to use it but this is a good start

Pour whole bottle in 1/4 to 1/8th tank of gas. Go drive, preferably hard, then fill up when almost empty.

also try pouring directly into the carb. slowly and a little at a time.

Why do people say to do this? Whether you drive hard or not it's not going to work better or worse, it's still injecting fuel and the Seafoam, and it burns.

Does it loosen up the 5-6 ports in an SE?

For the same reason you need to redline it every so often, to blow the carbon out. I am a firm believer that if you drive it harder it will clean a little better. Not saying it is a noticeable difference, but every little bit helps. Also, dont use it much on a high mileage engine because the carbon somewhat helps to seal the engine, from what I am told.

Search, its been covered over and over again

Should you change the oil and spark plugs after using it? or is that only on piston engines?

kgray

Nope, not as long as you just add it to the fuel of down the carb. It'll actually clean your plugs for you. If you were to use an oil based additive, then plug cleaning/changing would be beneficial

actually....some people have told me that it has turned their oil back after using it....so maby you should check it afterwards

kgray

Maybe if you put it into the oil, which would do nothing to decarbonize, but COULD help clean the oil, also thinning it which could lead to smoking... The proven way to use it is to pour down the carb or with a little bit of gas in the tank and drive it like you stole it.

If your plugs are due for changing, change them 1st, hotter/cleaner spark is better for the cleaning process. The only way the Seafoam can change the oil is if you add it to the oil or your oil control rings are past service life. Seafoam can be added to the oil, then driven for a bit to loosen usual build up in the oil system. Oil will then need to be changed along with the filter. I also recommend draining the oil cooler, if so equipped, by removing the thermostat plug at the bottom of the fmoc.

Bob, depending on how much internal cleaning the engine needs determines where one runs the Seafoam through the engine. For general maintenance, a can in the fuel tank with each oil change will help keep the carbon build up down. If the engine hasn't had a Seafoam treatment for many miles and carbon is built up, then add 1/2 can to the carb at a fast enough rate to kill the engine, then let it soak over night. Add the second 1/2 the next with rpms raised to keep the engine from dying. This would be a good time to add a full can to the fuel tank which will clean the remainder of the fuel system.

yes, does Seafoam loosen the 5-6 port sleeves in an SE? I have been running mmo in the oil and gas tank and it hasnt helped the sleeves, but i helped EVERYTHING ELSE.

Kentetsu

It works. Put it in the gas tank as described and you can't screw it up. I used to pour it down the carb, or suck it up through a vac line, but in the end found out that through the tank works just as well.

Hey Bob, have you and Perfect Circle ever met up?
