just have replaced the parts that needs to be replaced. this especially in your engine bay. what would you do to a nice looking car with banging sounds if it ain't running? this i think would really need time...kasi most of the time pag may pinacheck ka na isang component...dun din lalabas ung ibang problems. so just be patient with it...there will come a time na prang hindi nauubos ung problems. i should know...hehe

bottom line is start with the car's performance...good maintenance habits will go a long long way.=)

ako it took me almost a year before i had mine painted. hehe...pero sulit naman.=)
