valves tick after sea foam
 

car just broke 100k miles the oteh day and ive been getting poor mileage from it after a tune up and fuel and air filter filter change, about 16mpg. timing is correct as i had the guys at the smog station check it. i bought a bottle of sea foam today and used it to clean up the injectors and valves and so forth through the manifold vacuum line. after all was done and the tons of white smoke went away i noticed th car was a little louder then before, you can hear the valves tick now. i was wondering if this was normal, or if there should be something done. car does feel easier now.
