Hi Gents,

I am having a ticking sound when I accelerating only. When I start the engine on cold, I hear no irregular sounds. One of the mechanics checked, and confirmed sound come from engine when drove thru. No check engine light or other related lights are on. Using 5w-30 on oil change. The Pump, alternator...belt are fine for condition.

First we checked 2each the VVT oil control valve assembly for condition, resistivity reading and turned 12v to see if it works, both passed.

Next we checked oil control filter by removing top cover, which were clogged, cleaned and placed back.

Drove thru to check if the sound would go away, but no success.

I've read thru and found out VVT Gears can do that ticking sound too, but if so then it should do in morning cold starts and mine doesn't do.

Please let me know if anyone had the similar situation.

Thanks
