anyone of you fellas or ladys used SEAFOAM clean exhaust and intake valves of your engines. i plan on using some this weekend and want to know if anyone here has try'd it in a kia. it worked great in my bronco i use it in the gas tank and master cylinder vaccum hose every once in a while. i've also used it to clean the injectors in the kia just not the valves yet. i was just currious if anyone has..
