riddle me this...

i have a 92 probe lx. it has a ticking problem. when i start it in the morning to warm it up it ticks till it gets warm and stops. when i drive,it starts ticking again. i let it sit at an idle for aprox. 15 mins it stops ticking. oil pressure is perfect. i am stumped on this 1 can someone help me out

its the hydrolic lifters in the cylinder head put 1/4 qt of ATF in there and it will free them up a little and then get ur oil changed in 1500 miles or so good luck
