ok so i just changed my oil, oil filter, air filter, and bought a can of seafoam and poured it into my oil and gas tank, drove for about 60 miles and nothing happened. there wasnt a huge cloud of smoke or anything. is there somewhere else i should pour it? i keep hearing about a pcv or letting some tube suck in the seam which will cause the engine to stall or shut off, but not sure what or where it is. can someone please help me? i am trying to pass smog. oh yeah, i bought a bottle of techron as well, but havent used it yet. pictures would be great help if at all possible. thanks guys.
