I have crower 1.6 rr's and comp behive spings and comp hardened push rod and you can hear ticking comming fro under the car at idle but when you are driving I get no sound. Is the ticking from rr's normal cause I have heard other cars that get this same ticking at idle with rr's.
Thanks

ticking with Roller rockers is pretty normal. some are quieter than others, even if they are exactly the same.(brand, model, or design). So long as the valve lash is set properly, I wouldn't worry about it.
