ok here is my prob. i have a eg hatch with a jdmb20b it has a ls head. yesterday i heard a ticking noise coming from the head. i opened the valve cover. and looked around and one of the rocker i guess u woul say is loose moving side to side. and the top bolt is loose enough to move with your finger im guess thats what is ticking all the others are pretty tight but some are loose feeling. do i just tighten the nut?? or does it have to be done a special way. let me know hanks

 

Look up the specs for the distance between the top of the valve stem and the rocker arm. adjust them to spec and then tighten the locknut.

 

thanks
