Should I Seafoam the RB?

[curbsurfer253]

I've Seafoamed a few Hondas with great results. Would it be a good idea to run a bottle through the rb? If you think I should...I put 1/3 in the oil, 1/3 in the gas, and where does the other 1/3 go?

I DID MY RB20 WITH GOOD RESULTS... I USED A WHOLE BOTTLE FOR EACH SYSTEM AND RAN THE MOTOR WITH IT IN THE OIL FOR ABOUT 10 MILES.

LOTS OF BLACK SMOKE THEN IT CLEARED UP AND IDLES BETTER.

THE OTHER 1/3 OR BOTTLE WOULD GO IN THE VACUUM SYSTEM BY WAY OF BRAKE BOOSTER OR OTHER MANIFOLD VACUUM SOURCE.

i heard it ruins the o2 sensor is this true?

DIDN'T DAMAGE MINE ANY...

i was thinking of doing this too, but someone said it kills the O2 sensor and spark plugs.

more to the o2 sensor than spark plugs. just remove the sensor and plug the bung with a bolt when you do it.

Yes it will dirty up your spark plugs.. so you should use a cheap set of plugs when you do it.

It's not supposed to damage your 02 sensor, but doesn't hurt to take it out.

I'm personally not a big believer in using products like that. If my engine is dirty I'd rather dissasemble the motor and clean it myself.

seafoam has worked for years... but you have to remember that cleaning you engine can cause problems... rather than solve them. I'm you have alot of buildup that maybe the only thing preventing a leak and if you run the cleaner through it it will break down the grime can cause a leak.

My plugs and sensor were fine after the process but if there is alot of carbon your plug may get fouled along with the sensor.
