What would seafoam do ? Destroy the rings. Ive heard its safe though. But i have used it and i didnt really see a difference besides the fact that it clogged my o2 sensors. I got my compression checked after i used it ...150 in all 4. Im not sure if it was like that before though. I should have had it checked prior. Anyway now my idle is funny im not sure if that has anything to do with the seafoam.

Seafoam cleans and does a damn good job of it. Why didn't you take out your 02 sensors before running it throught your car?

Yeah. And I've heard that after using the seafoam - the black **** will come out of the exhaust for a few days.......its supposed to loosen the baked on dirt and grime.

That makes alot of sense now but i checked all the threads and nobody mentioned it. Also on the can itself it says o2 sensor safe. But i guess that means the product is safe, not the carbon that it breaks up. Anyway i cleaned the o2 sensors and they worked fine after.

carb cleaner

black **** on your bumper is common for modified cars. is your car 100% stock, meaning nothing modified, only maintenance work with oem parts?

Depending on what it's contaminated with, some have had a little success hitting the element with a MAP gas torch flame.
