Thx for the info, will try the rp 20-820 filter next change. I think the tick sounds the same as before redline, but it lasts only a short time after cold starting. Tick lasted a lot longer time b/4 redline. Do you have a preference on model of OBD II code reader?never needs replacement until you get a p0300 range mis fire code, then you need to verify. Try a 20820 rp filter next time if you can. Did the tick chnage with redline at all, or always the same? If it is the same could be bolts.
Redline is different then rp or any oil on the shelf, heavy ep/aw additives, poe ester base stocks, super high mply, most people that try it says it gives their vehicle a butter smooth effect. But as good as it is, it cant do squat if it is exhaust related, only if it is lifter related, and 50% of ticks can be either way.
