yeah, im having the same problem with my 02 galant, it ticks for a few minutes then goes away and i dont hear it nemore. i thnk it needs to be tuned up. it may be coming from the motor

If you are talking about a tappety sound (clicking or ticking from the top of the engine) then it is probably your hydraulic lifters. A few good oil flushes and some hydraulic lifter treatment should sort the problem, but the sound is more of a problem than the engine getting premature wear.

i am also trying to change the lifters, tapingnoise is just killing me. It comes on slow engine if rpm are over 2k it goes away.
