my car at idle ticks...i recently put a x pipe, gears and a chip....when i rev the car the ticking gets faster....sounds loud like in a drive through.....my friend at ford says it is a exhaust leak...and some other dude said it sounds like my valves are messed up...i dunno what either sound like.,... my friend at ford sais that if it were my valves i would notice the performance of my car and it would sound alot louder that just a ticking....the ticking i have now is pretty bad....
